I'm childish and I like things like this, so, how do you do it?

KFNWEGM - what is this?  It's Gear number and temp, but what are the units?  Target RPM?
KFTVSA?
KFVAKL?
KFZWMN?

Anything else?

The JCW Mini does it, how do we make ours do it?!

KFNWEGM is like a threshold for fuelcut. When rpms drop, fuelcut is disabled from this value downwards. So if you want gargles and pops for the entire rpm range and all gears, set it higher than your rpm limit for example.

KFTVSA is the time in seconds i think before fuelcut is activated. But its active only when clutch is depressed. At least thats how ive seen it work on Volvos.

If you want bangs between shifts, lower KFZWMN in the lower load parts.

Sorry my english... (:

I would also like to know

The post RIGHT ABOVE YOURS explains it.

[edit]
Summary:
CWSAWE : 1 (check FR this is ECU specific)
KFZWMN: -20 to -30
KFZWOP: first row -20 from original value
KFZW/KFZW2: match KFZWOP in changed areas
KFTVSA: duration (e.g) 2.55 sec
KFTVSAKAT: similar to above

Will add to s4 wiki time permitting.

See rest of thread for more details.

it doesn't work  :(

It is working, but it's not that aggressive.

I've flatted the whole minimum ignition angle to -96, and it gargles all day.

Once its really hot it seems to do it really well, but I think I need a louder backbox; as its pretty quiet.

It's better, though.

-96 is too much imo. Try -35 to 40 or so. I guess this is vehicle dependant.
As for louder bigger bangs you need to keep in mind that for an explosion you need both fuel and air. Fuel is sorted since you disabled the fuelcut, but you need a way to have some fresh air in the exhaust pipe as well. Deacceleration maps for enrichment and and enleanment are the ones for that i think.

I should add that stock catbacks and downpipes dont give the desired effect as good as a louder catback and catless downpipes

I've got
KFTVSA set to 0.8 second between 1K- 2K and 2.8 seconds between 2K and 4K and set from 60c
KFTVSAKAT set to 1 second between 1K- 2K and 3 seconds between 2K and 4K
KFZWMN set to -48 between 1K and 3.25K

It pops/bangs loud and deep between gear changes, even if accelerating slowly and gargles on lift off, but never noticed flames yet, unlike over 4K the NLS kicks in and turns the exhaust into a flame thrower.


That explains why I don't get bangs when I just lift off in gear

There a EVO a keep seeing locally and it bangs and flames on gear change and lift off, it's loud.

Brought my KFZWMN back down so -50, will go flash and see how that is! :)

Perhaps with CWSAWE
http://nefariousmotorsports.com/forum/index.php?topic=277.0

Changed mine already! :)

None of these maps are defined for the ecu I really want to do this to  :-\

If you disable the fuel cutoff it should already work i guess? The retarded ignition during deccelaration will cause your noise. I had it all the time on my first gen lpg car, no fuel cut on those systems.

I hope you guys aren't doing this with cats in place... It's a fast track to catalyst melt down. Also a good way to explode a muffler... Ask me how I know! lol

in which load area in KFZWMN

That's why KFTVSAKAT is zeroed out (at least mine is empty - stock), isn't it?

Must've been low quality cat and muffler. I had a sport catted downpipe. Used antilag a few times and nolift shift more often. I recently cut out my cat since it was off anyway and no damage to the cells whatsoever. And all my mufflers and flexpipe is in good condition too

I agree with you!

I've tried this and had limited success

I've got it popping lovely on let off above 5k rpm with -40 ignition on the lowest load row

But I can't get it working anywhere else in the rev range, what load areas are people editing?

Also, does KFZWMN affect cruising throttle/loads? I'd be a little hesitant to adjust it if it does

that is also my problem

mine, too.

Try not one lowest load rows in kfzwmn but two lowest rows. Then set kftvsa to lets say 20 seconds for the hole map.

On my Med9.1 the max value in kftvsa is 2.55sec :(

Dont know nothing about med9. On my ecu, me7 it is 25 seconds, but setting it FF didnt work. So i used 20 seconds instead

Same here for ME7.5, I've changed it to 2.50 (incase it doesn't like FF's) and will retest.

Fuel staying on though isn't an issue, although I have noticed sometimes it cuts (most of the time it doesn't).

I've changed the bottom 2 rows now in KFZWMN under 5k rpm, will report back my findings when it's flashed and I take it for a drive.

ok, so i will change it back to 2.5 sec. 

how much degree ignition at the last 2 rows ?

Try -30 or so. I had bigger bangs when shifting at low-medium loads. When wot shifting, i didnt get bangs so often. But for wot there is nolifft shift anyway

Edit: maybe my factor is wrong and it is actually 2.5 sec max

I'm just saying that dumping raw fuel into a nearly red hot catalytic converter is not a good thing, just because it works and you haven't had failure (yet), doesn't mean it's a good idea.

No joy here :/

Still pops over 5k but nothing under at all, even tried changing kfzw a little but given up my quest I think!

Might be due to my exhaust as it's a resonated Milltek, but is 3" DP & decat

I have it doing this on the Astras :)

ok how it work ?

i think fuel cut is off

Where do I start at finding these addresses? I can't find them listed in the map pack I've got, and a Google search hasn't helped. Any help much appreciated

I'm getting it to gargle, but no real flames or bangs tbf.

Tried various settings and it's all a bit meh.

post your file

As requested, thanks  :)

As i said, you need air for the fuel to ignite. I know nothing about these maps, but find a way to keep the throttle open during overrun.

I don't know, just guessing, but even on overrun the throttle doesn't completely close does it? Would it not just return to it's idling state?

I dont kniw either. Easiest way would be to log throttle angle or smth during overrun.

And even if it is in idle state, one must remember that you need a lot more air for this amount of fuel to make bangs and flames. Stoich is roughly 14parts of air and 1 part fuel. Imagine the amount of fuel being sprayed into the exhaust and how much air there has to be for a burn to happen.

KFNWEGM
19A8D 8x5

KFTVSA
19AB5 8x5

KFVAKL
1919C 7x9

KFZWMN
178DA 12x16

Many thanks!

So its far too rich... how do we lean it out just on overrun?

And what about cam overlap with VVT on decel? I don't even know if that's possible as I haven't played with VVT...

I'm confused regarding KFZWMN.

What is the X axis? I assume load? Is everyone just lowering the two rows at the lowest loads, to a flat figure?

This seems like a big change, which is why I'm questioning it, perhaps I've misunderstood?

See attachment. Thanks

KF=Map
ZW=Ignition angle
MN=Minimum

Lowering it allows you to call for a later ignition angle.

Thank you for the explanation. So one last question if I can, when people are lowering the lower two rows of data, it's at the lower load, ie the top two rows of the table? I assume this, as obviously overrun is low/no load.

It work perfect on med9.1. There are 4 map for ignition and then it bang by shifting.

Tweaked my map and it's gargles, pops and bangs.

Here's a quick video of first test.

https://www.youtube.com/watch?v=F4MiSsTjDfs&feature=youtu.be (https://www.youtube.com/watch?v=F4MiSsTjDfs&feature=youtu.be)

My maps attached in jpg

Can you give me the map locations of the maps your change?

What file have you got?

8n0906018ap_0003 like yours!

Edit: Sorry didnt see the pic!

@dayofthejackal Many thanks  ;D

It has been working great for the last week, but after a few acceleration runs on a bypass the popping and banging stopped.

I reset the ECU and the popping and banging is back.

Some sort of adaption?

What do you mean by reset? Clear codes? Ignition cycle? Re-flash?
Mines been working spot on so far

Tried clearing codes etc but didn't work. Disconnected the battery for 30 mins and everything is working again.

I used your settings above, but forgot to change CWSAWE, so I've done that today. I noticed the timing was dropping when clutch depressed with engine at idle. I was doing this fine for about 5 mins, while monitoring injector time and ignition timing. It soon stopped changing though. I put this down to the engine being warmed up. Perhaps it's stopped on mine now, like it has with yours? I'll monitor it tonight and see what happens

Fuel trims kicking in perhaps?

Are fuel trims active on overrun? On overrun, I thought the fueling would go into open loop and disregard any trims?

Today I tested this and it disables overrun fuel cut , but I still can get ignition timing under -3 degrees?
Do I have to also change KFZWMS?
And how I can keep tb open about 40% on overrun and over 3000 rpm?
And we also need more fuel than 1.7ms so what controls fueling in overrun?
Yes this is ful race car so no problem about melted engine =)

I have now schanged:
KFTVSA
KFTVSAKAT
KFZWMN

Got it work.
I didnt change base ignition map to allow atdc  :o I feel iam idiot  :D
Fuelt trims seems to be off in overrun.

Wonder what would happen if the SAI system was left running? That would provide plenty of air into the exhaust....

youd need to activate the n112 and allow the vacuum to the actuator on the head to be open on decell too for that to work

That would be a similar thing then to the SAS system on the Evo's wouldn't it?

They utilise the system for very potent pops and bangs, worked brilliantly on mine.

I think sai pump is not strong enought to pump air in exhaust manifold.
Normally antilag in race car takes air to exhaust straight to boost hose .
But that is not the problem if we open tb about 15% I can say that pops and bangs are strong enought to keep turbo spinning.
So we need to find what map controls tb angle in overrun

What map are you referring to as the base ignition map?

Probably means KFZWMN?

It was mentioned in a previous post that KFZWMN was changed, just wondering if KFZW was changed at all.

I think 5% throttle would be sufficient, I'm pretty sure last time I checked the injection time stays at about 1.8ms on overrun

Hi,
where can i find these maps on a 8E0909518AK file?

Someone already done this to a 518AK?

If it could done with Mapswitching ( http://nefariousmotorsports.com/forum/index.php?topic=7133 ) would be awesome i think...

anyone able to help find the maps needed in this ecu file?
I have several damos but mostly 032hn and 018cb files have helped.

I believe cwsawe is @  1ab41

I cant seem to line up the other maps tho?

Original file attached

Am I right with these?

KFNWEGM = 19C7A

KFTVSA  = 19CA2

KFTVSAKAT = 19CCA

KFZWMN = 16E80

DO NOT USE THIS ABOVE. ECU WILL DIE,


Anyone actuall have  the location for cwsawe on this ecu I cant find it at all

I tried this briefly on BPY med9 by altering KFTVSA and MFZWMN and my EGT probe in manifold showed a big increase in EGT on liftoff, over 1800f. Could be an issue if you're already pushing the limit and then let off.

I tried this with just adjusting the timing, and it works quite well - a nice pop on heavy gearchange and a good crackle when revved hard, I just adjusted KFZWMN to -37.5 at 0-30% load, 1480+rpm
I have a 2.5" turbo back magnex with decat, this is about as extreme as you can make it sound. It never makes a peep in daily driving.

https://www.youtube.com/watch?v=FW81xF3Q7gU

It cracks and bangs when revved hard, but only when the vehicle is moving. Suits me though.

Anyway, I'm reasonably happy with this but I'd like to experiment with a little bit more, but I'm having trouble finding KFNWEGM, KFTVSA, and KTVSAKAT with any confidence in my bin (032RP Ibiza Cupra R 1.T BBU)

Still looking for the needed maps at 518AK file  :'(

*push*  :-\

Would just like to thank you all for posting about this. While the addresses and names weren't the same in my ecu. I was able to use what I learned from here and made it work on my allroad...     enjoy....
https://youtu.be/MvqYbC4JxHA

Hi all,

I don't achieve to make gargle sound. It only pop one time in exhaust when I let off accelerator: KFTVSA / KFVAKL were increased, KFZWMN was decreased (-37,5 between 10 and 50% of load from 2000 to 6000rpm)

Could anyone help me by posting a csv log when he let off accelerator ? My ignition timing oscillate and my throttle shut fastly;

you should have made this changes (for my car it worked with this):

cwsawe = 1
KFZWMN @ low loads ~ -20 is enough... if you decrease it to -40 you are just producing heat... thats not really good...
KFZWOP @ low loads ~ x-20...

now you should hear it (it works better when the car has operating temperature)... please take logs and improve it by yourself by changing some other maps.

Thx !nfern0,

I don't find cwsawe and I'm not sure to have this map in my ECU;

I attached my ecu file, if someone can help me to find it !

Do you know if you have a clutch pedal switch? if not it's not neccessary, because cwsawe should be 1. If yes (cwsawe = 0), you have to find it, otherwise fuel is injected after off throttle only when clutch pedal switch is active (gear change when accelerating).

Unfortunately i can't help you to find it...

Yes I have it, used for cruise control also.

I will try to desassemble the .bin to see  ???

KFZWOP at minus values makes it really pop..  I've got it at -20 and its really loud, almost a bit too loud.

Bringing it back up a little to stop it.  But all of these changes and it'll pop between shifts and bang like fook coming down the revs.  Just the ticket!

Hmm. Kfzwop? Only low load areas? Didnt realize it had an effect on this

I would not touch KFZWOP, IMHO it seems better to change KFZW maps.

So, KFZWOP or KFZW?

I can get a single pop on let off throttle, but no gargle. I've got de-cat 3" downpipe to 2.5" Miltek non-res system.

@adam- Have you got a video of what yours is like? Am I right in thinking you're an Octavia vRS owner?

Take logs. You have to decrease your zwout to the right values. an you need fuel...

So.. take a log and look at zwout and lambda (AFR) @ off throttle, then you see what happens. then take a look at the FR and understand how zwout is calculated. also take a look at BBSAWE.

If you understand this, you will get your pops. :)

I've used KFZWOP because I wanted to try.  I guess they're suggesting to use KFZW because WOP is optimum and you shouldn't be playing about with that unless you know what you're doing.  I'll try KFZW and get back to you.

Nah, I've got a MK4 Golf.  It's a forged 1.8t, K04-064.  About 340/350bhp just now. :)

Sounds good Adam, I'll do some more reading....!

After a bit of logging I've found on low speed lift off I need at least -10 to gargle and pop and -18 to bang, but -27 seems to give the loudest multiple bangs on gear change and over 4k lift off.

I know what you mean, even the slightest lift off gives me multiple bangs and lifting off on the motorway just sounds ridiculous, but I like it.

Tried KFZW at -19.5 instead of KFZWOP, but found it gave me a lumpy idle. So I have gone back to using KFZWOP for now.

Could someone point me to a thread regarding KFZWOP. I don't understand it myself. I tried doing some research, but haven't really found much. As far as I know, as it's the optimal ignition angle, this map is used in all situations? Also, KFZWMN is the lowest angle it can use, so how does KFZWOP make a difference? Just to play and experiment with, what is regarded as 'safe'?

On another note, since this mod, I've noticed the instantaneous MPG on the cluster doesn't change to --- when on overrun. I understand this, as the fuel cut on overrun has been switched off, so it's still using fuel. But, KFTVSA is the time delay for fuel cut. My maximum reading in that table is 2.5 seconds. Shouldn't the fuel cut switch back on after this time?

Thank you all...

This is what I've got set at the moment

The idle problem with KFZW was with the load% axis and the minus timing falling on the idle.

Idle load 18%
Minus timing 10%
Normal timing now 17%, before 20%

I now have my perfect idle back  ;D I have also reduced the minus timing under 1,500 rpm on low load to make it a gargle and not bang for casual driving.

From your logs, does the timing go down to minus' and then to 0 and back again continuously?

Mine is doing that and is confirmed by the bangs - pops and bangs -> quiet -> pops and bangs -> quiet

Anyone have any suggestions to what could be intervening?

It did on the lumpy idle - then + then - etc, but not on lift off I just get - until idle or throttle re-applied.

Hmmm, need to do more digging...

zwout is zwsol within the borders zwbas (high border) and zwspae (low border).
if you lift off and want bangs you have to get a late ignition, so zwout has to be late. either zwsol or zwspae is limiting this.
you have influence on zwspae mainly with kfzwmn.
zwsol is zwopt +- dzws. zwopt you get out of kfzwop.

I think this should be enough information to get it. read and learn. :)

I am not sure if this is what you wanted to say but it seems you suggest that KFZWOP has influence on real timing which AFAIK is not true.

AFAIK KFZWOP is only used in torque model to calculate engine torque while real timing is based on KFZW(2) (of course corrected by other maps and knock adaptation/actual knock retard values).

If B_nozwe = 0 then you use zwsol ( = zwopt +- dzws).

I didn't had the chance to log B_nozwe and didn't had the time to get into the topic of B_nozwe. But what I had seen on my logs, the car uses zwsol as your ignition angle when lifting your foot. So it seems that B_nozwe is probably 0.

It seems there have been some unanswered questions in this thread, as well as some getting mixed results, and not everyone is changing the same combination of maps. I'm also curious if ME7.1 and ME7.5 use the same maps to achieve these results. Some people that post of success don't mention what ecu/engine they're doing what changes to. Can someone answer a few questions?

1. Does KFZWOP need changing to get da bangs? I was always under the impression it was just used for the torque model and shouldn't change real world timing values at least directly?
2. I see mention of KFVAKL but it seems like some use it and some don't.
3. I've changed everything mentioned in this thread except KFTVSAKAT which I was unable to find (M box). No pops or bangz yet. Can someone help me find this map? I assume it would be all 00's like I saw it in other definitions I used to find the other maps, but for some reason don't see it.

I'm about to go log and try and change things around, but I need to find KFTVSAKAT first. Am I right in assuming this map also needs to be changed in order to get the desired effect? There was a single post saying that gargles happened JUST changing KFZWMS...Wasn't sure if he meant "JUST along with all the other maps you need to change"

I'm trying to get this working on B5S4 Mbox ecu if that matters in some way.

edit***KFTVSAKAT follows KFTVSA in almost every file I looked at except for the 551G and 551M (probably more, but this is what I looked at). Not sure if I need to worry about this map since it doesn't seem to be present in my file, or find the equivalent of it somewhere else. If you have a G or M box, what did you have to change to get this working? Thanks!

My car has a ME7.5 (8N0906018H).

I will try to answer your questions from my experience.

1. Yes. There is a constant delta between zwsol and zwopt (upper thick red bar). -> This has to be dzws. AND your ignition angle is following zwsol when lifting off (take a look at the screenshot of my log). There you see the current ignition angle is following zwsol. It seems that is only following in the case overrun and fuel (AFR ~ 14.7). If fuel is cut then the ignition angle follows another value. But this is not important for bangs. Important is, that ignition angle follows zwsol when you lift off and have fuel!
So there is a second delta between zwsol and zwspae. I want that ignition angle follows zwspae in overrun with fuel. When i decrease now my KFZWOP values @ low load and @ RPM where i want pops by about this delta (or some more) the ignition angle will follow zwspae because that's the hard lower border, even if my zwsol is lower.
I hope this is now enough to understand how to get the pops?

2. you only need KFZWMN KFZWOP and CWSAWE to get pops. Everything else is for details. for example you can increase the duration of fuel injected with KFTVSA.

3. KFTVSAKAT is IMHO only needed for the case you lift off foot when you had long WOT runs. -> rich AFR in catalyst and then you don't want to have immidiateley only air there. (much heat, much fuel... then air... -> big bang). Since there are values in KFTVSA it makes no sense to use KFTVSAKAT, because the function uses always the higher values (KFTVSA).

Thanks for taking the time to explain things in such detail. Going to try lowering KFZWOP in the appropriate fields and see how it goes!

Can someone help me find these maps on my cupra 2.0 tfsi?  its 9.1 ecu 1P0907115C 386637

Is there a way to find cwsawe? Something to look for? Its not defined in the map I have

Which ECU?

Hopefully this one, any help would be much appreciated

Thank you

I would try 0x11625.

thank you, il flash it today and try. How did you find it?

By comparing with other defined file - this is why I am not sure if it is proper location as all defined files I have are quite different to yours.

For 8E0909518AK_0261208230_368072 SW 0003

CWSAWE should be @ 0x11925 (this is based off conclusions with  tt 1.8 BAM ols file and address given by tjwasiak for 4B0906018CG bin)
KFZWMN_0_A @ 0x124ED
KFZWMN_1_A  @ 0x125AD
KFNWEGM_0_A  @ 0x1A242
KFNWEGM_1_A  @ 0x1A26A
KFTVSA  @ 0x1A2BA
KFVAKL_0_A & KFVAKL_1_A yet to be found

As i´m totally stupid about the abbreviations of Bosch ecus, how does these maps translate into english and is there maybe a list of them?

KF probably means Kennfeld and KL probably means Kennlinie. SA probably is Schubabschaltung which could be translated into overrun fuelcut.

I would definately like to implement that into our Siemens ecus but its pretty different and it definately would help to know what to look for.

CWSAWE: Codewort Schuabschalten Wiedereinsetzen:

Codeword
Overrun Fuel Cut
Merging Fuel & Air (?) - Wiedereinsetzen is the opposite of overrun fuel cut, if there is a torque demand (Idle, Driver...) the engine starts to combust again after fuel cut.

KFZWMN: Kennfeld Zündwinkel Minimum

Map
Ignition Angle
Minimum

KFZWOP: Kennfeld Zündwinkel Optimum
Map
Ignition Angle
Optimum

I´m german, so the its even easier for me to understand without the translation :)

Thanks alot.

Try Nye's list: http://s4wiki.com/wiki/Motronic_abbreviations or some of the info from this thread: http://nefariousmotorsports.com/forum/index.php?topic=3265.0

Both have helped me in the past.

Consult the FR.

Please read the stickes, and my tuning page.

http://nefariousmotorsports.com/forum/index.php?topic=400

DID YOU EVER FIND THE LOCATIONS FOR THE REST?

May i ask what FR means?

(edit)

Alright, you mean Funktionsrahmen, got it.

I updated with more locations I just need to locate KFVAKL_0_A & KFVAKL_1_A.

Thank you, I was really struggling to locate these. Have you tested out on the a4 yet, so far I've done the following and not a peep. I've got not cat and free flowing exhaust.
CWSAWE TO 1
KFZWMN -18 LOWEST TWO LOAD LINES
KFZWOP x -20

You need to adjust KFNWEGM too. Where do you think the fuel is coming from?

I was going to adjust that last night but did not find the map location. I will adjust today giving the chance now I have the location.

Thanks

I would prefer using KFTVSA over KFNWEGM.

@seany260: Probably your KFTVSA is zero all over the map.

You reduced the ignition angle in KFZWOP all over by 20? That's not a good idea...
Try only reducing the lowest load line and RPM from ~2000 to ~5500. Maybe the second lowest load line could use some reducing too (~-5°KW). But leave the rest like it was.

It should also be enough, to reduce the lowest load line of KFZWMN.

Log your data an take a look if your o2 sensor is measuring AFR of about 14.7 when you are off throttle. Also take a look @ zwist.

No no, just the lowest 2 lines of KFZWOP reduced by 20.
I'll make some edits 2night and log all the variables needed afterwards.

Many thanks for the help.

I made the changes suggested and still nothing, I have not got a log done as of yet, just tested on the way to work this morning. What are all the variables I need to log?
pic of my changes.

Please stop shouting, or I will delete all of your all caps posts.

I take it you mean asking for help?

Ok I understand now, I don't do that purposely just being lazy and not turning caps off. Noted for future, thanks.

Do you have WB? Whats the afr during overrun?
Kfzwop should be - values?

you have to log at least:

RPM, WPED, RL, AFR (do you have wideband?), ZWOUT, ZWSPAE, ZWSOL

KFZWOP should not be negative, thats ok. Are you sure your adresse of CWSAWE is correct?

If 518AK file is being referenced, CWSAWE plausibly located at  @ 0x11926 instead. I've had to compare and test with a 518F file & map pack.

Left Side 518F <-> Right Side 518AK

I have noticed that after switching 0x01 @ 0x11926 overrun pops continue.

Yes Im wideband, and AFR is stoich, load 15%. Ive changed the address as suggested by  'BlkSerialKilla' (thanks for the correction btw) but still no pops or bangs because what I can see from finally getting a log done is that,
Ignition angle is following 'zwsol' when there is fuel on lift off but is stopped from going lower because instead its limited by 'zwspae' on overrun and looks like i need to further lower KFZWOP.
Im going to lower KFZWOP to -values as suggested and see if this helps.
 

Ok! Log seems good! CWSAWE and KFZWOP should be ok! Your problem is zwspae. I'm wondering if your adress of KFZWMN is correct?

If following statements are true, then ~zwspae (there are some small values added... but not really much) comes out of KFZWMN:
- B_kh = 0 (no warming up of catalytic converter)
- B_st = 0 (no starting phase of engine)
- B_zwmns = 0 (no engine protection)
- B_sa = 0 (no fuel cut)

You could also log additionally zwmnms (ignition angle when engine protection is active), but according to the FR your engine protection is not active when B_sa = 0...

So for me the only reason is still the wrong adress of KFZWMN...
edit: you didn't log this with a cold engine? and I can't open your log... seems to be corrupted...

Engine was well up to temp. I don't know if this has an effect on this at all but I've got CWKONABG set to 0 as I've no cat fitted?
won't be able to check location of KFZWMN until later, but values in the table look acceptable.

There are two kfzwmn in the 518AK file I've noticed KFZWMN_0_A & KFZWMN_1_A. Also there is another one catalyst(s) heating KFZWMNKH and cold start KFZWMNST. Disregard the address, those are for 518F bin but if anyone can confirm or correct locations that would be great.

Edit: attached best efforts of locating maps.

I don't know were I got my location from but for KFZWMN but im using 16F9C in the 518ak 0003 file.
Calling for a second opinion on these locations, please?

That location you were using is actually KFZWMNKH.

Thanks for that.

Finally I'm getting some were, I've got little pops on gear change and short overrun. Just need to play about now with the other maps.
I've got KFZWMN(location corrected) set to -18 in the low load area and may try it at -30
KFZWOP x-20 in the first two low load areas.

Thanks for the help

I read through this thread and I want to make sure I've got this straight. Is the following summary correct? Is there anything missing, not necessary , or incorrect?

CWSAWE
-SET to 1

KFNWEGM
-SET entire table to your red line RPM

KFZWMN
-SET lowest two load lines from about 1500rpm and up to about -18

KFZWOP
-REDUCE lowest two load lines from about 1500rpm and up by about 18

That is a good starting point, you can adjust further depending on how well works with your setup. Ive got similar settings and I get gargle and pops but no bangs as yet. I need to log again to see what is going on.

I'm having a hard time finding CWSAWE and KFTVSA for the 018ch ecu.  I've found most other maps comparing my bin to the 032hs and 018cb bins but am not having any luck this time.  Does anyone maybe catbed know where to look? Thanks!

Having a few issues with this guys. Noticed the popping on lift off had almost stopped. Stuck VCDS on and reset adaptations, and it's back.

What is changing to stop this? What can I do to stop it changing?

I still can't find CWSAWE for my 018ch 360101 bin, but I'm not sure I need it.

My car now gargles a lot but the popping was all at the same frequency so I made the retarded timing a sawtooth pattern and now the ecu is constantly altering between -10ish and -20ish degrees and the pops sound a lot more authentic or organic.  Worth a shot if you dont like how your pops sound.

Did you by chance check fuel trims before clearing the ecu?

No, I didn't. I'll wait for it to stop again, and have a look.

I still can't get it to gargle on overrun, only get one bang/pop  ???

Here the result on my s3 tfsi med9.1:

https://youtu.be/KXnxHYSAkIA

cwsawe =1 KFZW -20° KFTVSA 2.5S 3000-6000tr/min

lunch control =  NMAXGA 4500tr/min

But I can not seem to do I will test flame has kfzw -30 °

Here's mine

'07 B7 1.8T (8E0 909 518 AR)

https://www.youtube.com/watch?v=t8u_olZpTLo

All I changed was CWSAWE to 1 and KFZWMN to -30 on the first 3 Load Columns

I can gladly say its been done at Siemens MS43, too :)

https://www.youtube.com/watch?v=mIBouQ4Hu5k

Now we just need to find a way to implement the more fun stuff like No-lift-shift, anti-lag and pseudo-launch :)

works on the 032RP
(https://www.dropbox.com/s/hlvdk1ml3wbm7mf/flame.jpg?dl=0)

KFZWMN to -30 on the first 3 columns
CWSAWE to 01
KFZWOP subtracted 20 from 1st column and 5 from 2nd column
KFNWEGM to max rpm

thanks pynoxim for the help with addresses

this works great on my r32 022 906 032eg

What is the purpose behind the KFZWOP changes?

i assumed it was to allow the computer the range to run the negative timing. i don't know that to be true but thats what i make of it. as far as my car goes the minimum timing table in stock form doesn't have a large swing of positive and negative timing so to keep the negative requests in the optimal range they need to be lowered? i dont know...

In my car KFZWOP wasn't needed.

Regarding KFZWMN load axis, as load is based on MAF and before when I had only two lowest load rows set to -30 I got good bangs when I gently rolled through RPM range. Now I set higher load upwards from 5000 RPM toc-30 too and now it bangs very loudly even when flooring it.
The MAF value doesnt drop in an instant when off throttle, so by the time it reaches lower load column, fuel is gone.

Hey guys,

can someone pls tell me how to find CWSAWE in 8E0909518AH 366871 (BEX)? Damos or A2L would be great also ;) :D

Thanks and greets,
Sonny

Edit: Some codewords like cwsawe are not easy to find without exact a2l... Or can someone give an advice how to find such short words?

8E0909518AH 366871 (BEX) attached. Would be great, if someone could tell me how to find CWSAWE in that file.

regards

0x11BD2

Its easy to find because its next to the ecu number.

Thank you for the fast reply.
But how do you know its not 11BD9 or 11BD3?

I see...
I think my compared damos differs too much from the file 366871.

thx

try and report please

has anyone monitored real egt with that mod?  ;)

I've thought about this.  Probably through the roof.  But it's reet, everything's still working 10k later.  Turbo has a lovely white dusting on it, probably because it's seen 1000*+.  Meh.

To everyone having some fun.. how long does your lambdas survive?? Mine after some time throw the "heater circuit" error.. Dont know if the fun worths the lambdas every 3-4 months.. What about your expirience?

Mine's been fine a year later.  NLS/AL used every few days.  No issues.

Same here. Over a year of flaming sensations and stock ECU wideband as well as sensor for gauge both going strong and accurate.

Thx for all the tips here.
Could anybody get this working on BMW 330i or 335i?

Hmmm maybe its the location i ve placed my O2??.. 500mm from turbine outlet..What the @#! is going on mines?? I feel its the explosions that rip off the heaters/ceramics..

Where to find CWSAWE in K-box? Tried to find out next to other maps but not sure if I got the right one.

Unfortunately it doesn't work (CWSAWE=1; KFZWMN: first 2 rows upwards 1500 1/min to -28°KW). I want to check values in KFTVSA but i can't find it in BEX-file... I checked many DAMOS/a2l but i can't find nearly similar KFTVSA at my file.
Would be great if you could take a look on this also. :)

Best regards!

Sonny u ve got kfnwegm tuned right? In my findings thats enough to disable fuel-cut and then just play with fuel and ignition.. My way for fuelling is with fkkvs.. It needs some tries to find the right fuel to ignite into the exhaust..
Yeaaaars ago thats my car overruning.. (at the end of the video..) Hope i can make some new vids..

https://www.youtube.com/watch?v=V41_uMIYsO4

Although you report not having problems with lambdas i ve changed quite few  4-5 over the past years with hard use.. No nls lc.. Thinking to move further away my sensor just to try.  In what distance you place them at the dp?

I don't want to disable fuel-cut completely (set KFNWEGM to 7000), only delay with KFTVSA (set to 2.5). I tested both already but I think my problem is on the ignition-side. Take a look at the attached files, please.


@Rl:
Maybe your lambda sensor got placed badly in terms of condensation in your dp. It's a big problem at cold start when the o2 sensor gets fully heated with the internal heater and a water drop out of the condensate in your exhaust pipe come across and hits the ceramic of the sensor. -> It breaks.
In the FR it's defined in the ATM:

atm-tmp-start
Berechnung fur Taupunktende Sonde vor Kat und Sonde hinter Kat

Very tricky to heat the o2 as fast as possible to use it for gas treatment without breaking it.

Did someone found a way to enrich fuel while overrun ? maybe with KFVAKL ?

and some MED9 seem to have problems with overrun fuel cut ( RPM falls extreme slowly), any ideas what could cause this?

King regards!

I did it with LAMFA, because theres a zero line which I referred to decelerating and which worked for me. I edited mine from aprox 2200-7300 RPM to 0.79 and now its finally banging loud, especially in higher RPMs 4000+.
I tapered the ignition timing lowest 2 lines in KFZW and KFZWMN from -48 low rpm to -12 high rpm

Only between 2200 - 3000 RPM its not making much sound while the ignition is like -31 there, but I am still working on it to make it gargle instead of banging, just like golf 5 GTI does, which sounds lovely.

Here a preview of what I got so far (Dont notice the gearbox sound, it because of the straight clutch):
https://vid.me/1lN3

Surely it'll be super rich at low loads (cruise?).  Remember it interpolates and 0% is not how it is.  Got logs?

To be honest its stoich at part throttle, but my wideband sensor just broken down. I will post some logs later

Finally got home so I can post my log. I was logging boost here but in the first of the log you can see little bit cruising @ 1750 with an AFR of 14.7.
Also added pic of the maps.

I also did some change on KFZWOP but I dont think its necessary to touch that one.
(with the zero line I ment the first line on LAMFA)

Could you do a video of high RPM overrun with those settings? Intrested to see/hear the results

Sure, ill make a video next time

Here they are ;D

https://vid.me/41JE
https://vid.me/2Xi5

I just drove home and somehow it started to run on 3 cil on part throttle and on WOT 4 cil so im gonna check plugs tomorrow.

I had these problems as well on the MED9.1   - cant figure out why.

It seems to work very good. In car pop sounds and camera microphone doesnt make the loudest video. Behind the car the bangs are probably louder

Has anyone managed to get reliable flames from this :) ?

I'd like touring car style flames on over run/like that duitters rs4 on YouTube.

I have it popping and banging on gear change and coming down the revs on decel, is it just a case of enriching it some more on over run? I've lowered the values within KFVAKL to try and enrich it some, just wondered if anyone had mastered it as such :P

Have anyone changed it for med17? I have made it on me7, MED9.X but i cabt pop and bang (schubblubbern) on med17... i have seen some cars with this rally sound :( but no one wants to say how they do this... :(

Post your ORI for MED17. It's just minimum ignition angle. If it's not working, you're not changing the right map.

here the file =) i have change some med9.X and some me7... but no med17 ever bangs any time... some tuners says i must play with the camshaft "nockenwellenverstellung"... but i dont know what i should do and which map...

Playing with the camshaft angle (Nockenwellewinkel) isn't necessary. The key is to have the charge ignited as late as possible so it's down the exhaust to make noise. You need to change the lower load, higher RPM minimum ignition angles to something quite drastic ATDC (at least -40 usually works well).

I'll try get a look at your binary and see if I can suggest where the maps might go. Do you have any definition for that file or are you trying as you go?

Hey, have professional damos from a famous german tuner.... but i can not upload it, because i promised it, thst i dont share it... i could look tomorrow evening for the map adresses in the file...

I have changed ignition angle to -40 and played with some other maps... no effect... i only finde one tuner which changed it with effect... but he dont want to tell how to do it... :(

I have done so much med9.x... ttrs, seat leon cupra, golf V GTI, Golf 6 R... all bangs but no med17 :( i will sens the map adresses...

To be fair, not sharing isn't exactly the spirit of this community. Especially stuff like DAMOS files which are propriety Bosch.

Aye, don't be that guy.

Whats the problem with MED17? Its all written here, what to do.
Its working fine.

Did anybody tryed that on BMW 330i N53 MSD80 and found a solution?

trying to find CSAWE in the 560ce audi 4.2 ecu.  anyone?

If only I was experienced enough to find these addresses in my 018p bin

Here is a video of this mod on my R32 swap
https://youtu.be/TuOmAk6TA14

I would've turned that music up even more...

has anyone tried to do this in m3.8?
i did a few changes to kzwop and minimum angle but with poor results, only got some tiny little pops in decellaration.
does this motronic have a map for "schubabschalten" or something like this? couldnt find any of this in my damos.

would appreciate some hints,

cheers

help

In my damos  KFTVSA map it's in % not in seconds. Why?

nobody can help me?

Because you are simply too lazy to post more information...What damos / what ecu number etc...map screenshot? axis? address?

(http://file:///C:/Users/Bobcrazy/Downloads/KFTVSA.jpg)

I hope it's worth There is no unit in the table. I thought it was in%.

The Factor ist wrong.

Verzögerungszeit = time for delay

Thank you, I could tell. What factor do I have to put in?

0,01 ;)

Perfect, trank you.

Ok im into this Pop thing me self now... soo

Anyone have these gangsters for my ECU?


CWSAWE
KFZWMN
KFNWEGM
KFTVSA

//Satan

Take a look at 018AA map pack, it has all these defined except for few axis. Aligned with 018AL perfectly.  ::)

Thank you Sir that helped me ALOT :) Ill be back with a movie :)

Got it to gargle and pop really nice when warm engine.. But one thing I dont understand is why the idle got really poor when warm engine and STFT seems to work only at low throttle and under 2300rpm?

Found the problem :)  I some how managed to get overcurrent through Pin 51.

Here's my attempt,

Managed to get it flaming really well on over run. Less bangs but I prefer it that way, track noise limits don't like bangs haha.

https://youtu.be/4oO6kaxIZAw

That looks awesome!

Would you post your settings for relevant maps too please?

Yeah when I get a chance tonight I'll post settings - it works really well. I'm trying to tune out the bangs and just have the flames :P

KFZWMN to -30 on the first 3 columns only between (4500 rpm and 6500rpm)
CWSAWE to 01
KFZWOP subtracted 20 from 1st column and 10 from 2nd column
KFNWEGM to max rpm
KFTVSA 2.5 for last two columns (I think this is delay time in seconds before fuel cut) I figured longer meant more chance of flames

I then added some fuel with lamfa between 4500-6500 rpm going for something like 12.4AFR (for the 50%) row as I figured I'm never cruising at part throttle doing above 4500rpm so the only time my car should see that area of lamfa would be when I lift off the gas at high rpm.

Not so much banging but lots more flames. Banging seems to happen when fuelling ends up at stoich below 4500rpm.

Does anyone know how I cut the fuel below 4500rpm as I don't really want the pops and bangs so much?

there is no reason to use KFWEGM then (btw there is skyhigh egts when using it even at cruise)
keep it stock and use only KFTVSA - its delay in seconds before fuel cut kicks in (try to play with KFTVSAKAT if KFTVSA wont work alone)
manage pop rpms by KFZWMN & KFZWOP

Thanks, have now set wegm back to stock. kftvsakat to zero below 4k rpm as I don't want any fuel below those rpm's. KFSTVA set to 2.5 for last two columns. WOP and WMN same as i stated in my last comment.

Ok i have tried this now.. and it pop a bit when i press down the cluth... But how do I do if I want it to pop more and longer all the way when in gear and clutch up? 

What are your settings? If you set KFTVSAKAT to say 10200 i think that should allow over run fuel all through the revs. Then make sure KFZWMN is lowered sufficiently all the way down from redline rpm to say 2.5k for the low load columns. Also edit KFZWOP for low load (first and second lowest load columns is what i changed) it should then pop all the way down the revs.

The problem is the lack of CWSAWE if I'm correct. It will only go into overrun when the clutch pedal is pressed... Unless you find CWSAWE and enable the overrun bit...

Ok So if understand this correct I can just extend my KFTVSAKAT this will continue even is clutch is not pressed.

CWSAWE is set to 1"

Maxing (or raising above you rev limiter) KFNWEGM will disable fuel cut entirely and (so long as KFZWMN, KFZWOP and KFZW(?) are set correctly) it'll pop/bang all the way down overrun.

If this is true I should be able to disable over run fuel below 4500rpm using WEGM right? am I right in thinking I can do the same with KFTVSAKAT by setting it to zero in the areas where I don't want any fuel to be added on over run?

there is lots more to the bbsawe you can play with than just 3 maps.

Adjust tvsatm to 100 or as high as you want in seconds,  in the rpm range you want. This will stop oneof the conditions that lets for overrun fuel cut off enable

Might be better to explain with few examples what i mean.

Road speed = 0 kmh
cwsawe or clutch switch input = 1
kftvsa delay time of 1 second
tvsag0 delay time of 2.5 seconds
Kftvsakat delay time 1.5 seconds
tvsabte delay time 3 seconds
Tank venting = OFF

Overrun cut delay time = 2.5 seconds from tvsag0

Different example.

Road speed = 30 kmh
cwsawe or clutch switch input = 1
kftvsa delay time of 1 second
tvsag0 delay time of 2.5 seconds
Kftvsakat delay time 1.5 seconds
tvsabte delay time 3 seconds
Tank venting = OFF

Overrun cut delay time = 1.5 seconds from Kfvsakat

Road speed = 30 kmh
cwsawe or clutch switch input = 1
kftvsa delay time of 1 second
tvsag0 delay time of 2.5 seconds
Kftvsakat delay time 1.5 seconds
Tvsabte delay time 3seconds
Tank venting = ON

Overrun delay time = 3 seconds from Tvsabte.

This is all worked out from the FR Chart.

Worth noting that in the 018CB 225 TT file, TVSAG0 = 0 seconds  and TVSABTE = 0 seconds.

So if your finding it pops or flames lots while driving but not very well stationary your problems lie either with tvsag0 or tvsabte

You need more than just cwsawe, kftvsa and kftvsakat to make it delay well.

Wow some nice info. Thanks :)

Obviously there are other conditions etc involved

You could mess with Kat temp upper limits etc to make it never activate b_sab at all

KFNWEGM is translated to "Resume engine speed map".

In other words, the RPM at which to restart fuelling after fuel cut-off. If this is set high enough, then fuel will never cut, it doesn't work the other way around though like you're asking for.

You're better off as you are and just dealing with a time delayed fuel cut if you don't want it fuelling all of the time.

Hello,
I have a few questions
- What does this do for the car (i.e build boost, or some other fancy thing, or is it purely cosmetic)?
- Does it build boost?
- If not, how come, since it's explosions near the turbo, I'd think it's the same principle with the ALS code


Thanks!

no
no
prtially yes

Hello ! I've also tried to make pop and bang; the vw group me7 & med 17 works perfectly. I can not run the system of med 17 & me 7 fiat. attached files.

I changed the following things:

-KFTVSA Ind.507A2 to 2:55 second
-KFTVSAVG Ind 5084C to 2:55 seocnd
-DNMAXH Ind 56086 to 0
-DKFZWMN Ind 5d0e8 to -30


but it does not work .

can you help me?

anyone tried this on a stock exhaust, saw that the vortex guys thought the backbox would blow up with NLS, so might apply to this as well?

depends on your ignition angle. Just don't go crazy with it and your exhaust will be fine

Hi all,
it does not work on MED17.5.20
is there another way ?

please help to find CWSAWE in 8N0906018S file. I found some .kp, where CWSAWE located in 15795.
But there 'FF' in 15795 allready.
Is it normal, or wrong adress?
Thanks

Try as @15789

Tiptronic owners don't forget;

"On projects with CVT transmission (B cvt = true), either KFNWEGM or NWECVTM is selected according to the condition B sacvt."

https://www.youtube.com/watch?v=hZQ4JSGGPNg

P.S. - Any later Motronic systems are likely to have the same or similar evolutions of this if a CVT/Auto, so could be why it's not working at times depending on conditions?

Yes.

Tu n'arrives meme pas a t'exprimer clairement et correctement en Francais, donc bonne chance pour que quelqu'un ici comprenne ou est ton probleme.

@others: give the guy a break, even in french he's not making sense.

The problem is that by rolling a low load, the car to the delay mode of the car advance will jerk, I notice that when the clutch pedal runs the ecu is using another card. Because the detonation does not occur and the speed drops faster but I can not find the map to be modified so that the delay time occurs only when the clutch pedal and actuates.

As i own such a car i can tell you that there are 2 - 3 ways to do it...Just don`t complain about the consumption afterwards..Mine is dsg too.
Stock catalytic system will not allow too much noise whatever you do.i don`t use KFNWEGM and everything else is just next to it...As for the negative spark advance just search for Saugro ZW maps as your car is by Default naturally aspired.

That said on a dsg car is really annoying having those sounds when you just need to cruise but if you set it up properly nothing will brake your nerves on D mode.

bah ouais t'as éditer tu t'es trompais, dis moi, ton bac, tu l'as eu dans une pochette surprise?

Thanks for that. I am running without cat, but anyway i did just a slight modification.. So now i have some moderate gargle thats enough.. i agree that to much pop and bangs gets annoying on the VR6.. But a little bit of moaring and so on is nice to have.. consuption goes up yep uhh..

You need to look at min ignition table and the delay tables. Also dropping the low load high rpm rows of kfzw will help too.

Play with decel enrichment too

Good morning guys !!!!!! one more to enter the joke !!!!
Today I blinked the file with the changes mentioned here. !!!!! Several bursts in deceleration.
Now I'm going to adjust to come only at the highest rpms above 4500. In town it gets kind of boring that all the time. I also want flames in the gears !!!!!!
let the games begin!!

Hey Frenchguys -> English please!

Can someone tell me if i found the correct maps for pops and bangs for a Bosch M3.8.3 Audi 1.8t AGU 150PS.
I have attached the original file (Stage 1 ohne schubknallen) and the test file with my try of pops and bangs (Audi A31.8t AGU schubknallen ohne Klima).
I also attached the OLS file with the maps.

Hi Guys, I read on a Facebook Site from a Tuner that he doesn't work with negative ignition angle! He says it would be better for the engines to use instead positive angles! Can somebody here tell me if this is working or if somebody tried that allready!?

Regards

No, because that would make power and the motor would continue to drive the car even though you've lifted off. 

Ok, that is exactly what I thought about,.......did somebody here realise to make the Gargles only on manual mode on DSG car with MED 9.1!?

Havent read all the pages for now but is there way to turn it on and off on med9?
Car is mk6R CDL with DSG. Maybe it can be done in the different modes of the dsg?
Did read something on facebook for mk6 med17 with climatorinic ac button.

Hi. Im looking for:
CWSAWE- @?
DNASV- @?
KFNWEGM- @19E4E?
KFTVSA- @19E72?

S4 B5
8D0 997 551 D

Can someone help confirm the location of CWSAWE in my 018CH?

It looks to be in the area of 1160A, 1160B or 1160C.

try @1160B. If not, try 1 bit to left and right from here.

rogerius:
I just learned my own method of finding maps, but it doesn't apply to these 8 bit single values. I need at least 9 bytes of data to use my method. I can contribute by sharing the addresses below from my friends 03 Golf GTI. Unfortunately the locations don't match for my ECU and I can't find them. I really just need CWSAWE please (8E0909518AK 368072).

ECU 06A906032PL HW 0261208188 SW v367517
CWSAWE - 0x1124D
DNVSA - 0x11252
KFNWEGM - 0x19AF5 5x8
KFTVSA - 0x19B1D 5x8
KFTVSAKAT - 0x19B45 8x4 (Delay time for Schubabschalten during high revs and high Cat temps)

Now that I shared my buddies GTI locations, can someone PLEASE help me and share the A4 locations for CWSAWE and if possible DNVSA. I need them for ECU 8E0909518AK HW 0261208230 SW v368072. I have attached the original BIN.

Sharing is caring and will lead to greater community knowledge, skill and power ;-)

EDIT: I looked hard, could it be this? Address 10EEA? Any hex area I should be looking out for?

Cwsawe is a easy way to bricking an ecu if you are not 100% accurately finding the maps.

It's also not needed when using kfnwegm

You're right. I found the right one at 0x11926

Here you go, I can help with others also if needed.

CWSAWE 0x11926

I´m trying the same , in MY2011 GTI MK6 DSG.

I think it is done through the maps DNWEK, DNWEKFS, there are delta RPM with AC button ON...

you are correct :)

I have tried it without success (bang & pops working always :(  ):


All ZWMIN maps changed in low loads to -20º.

All ZWOPT maps changed in low loads to -20º.

DNWEK & DNWEKFS set to 7100 RPM.

All another maps stock (KFNWEGM, KFTVSA, KFTVSAGNG).

I think one of the two maps DNWEK/DNWEKFS are for condition AC-ON, and the other AC-OFF, and I set the two maps to 7100 RPM, can be the error?

My KFTVSAGNG stock are setted to 25,6 s from 3000 RPM to 0 RPM, but with this configuration Bang & Pops always, so I think that this aren´t the error.

My CWSAWE are set in 32, so i dont touch it.

I think it can be done in two ways, one with the rpm threshold, and another time delay (KFTVSA)
 
Some help? Thank you.

What is DNWEKFS? I couldnt find it in the FR.

Yes, DNWEKFS dont appear in MED 17.5 FR. In my damos appears:

Delta n für WE bei Klima (AC) - DNWEK

Delta n für WE bei Klima (AC) und Bedingung Fahrstufe - DNWEKFS

Bedingung Fahrstufe is "Condition driving stage".  I find this words "Bedingung Fahrstufe " in other maps, can be DSG related? (P/N/R...) who knows? :)

Hi!
Can you help me to find
CWSAWE
KFNWEGM
KFTVSA

Orig file attached. Thanks in advance

I'm going to be trying this on my MK6 GTi DSG tomorrow. I'm Assuming CWSAWE doesn't need to be changed since it's a DSG, and also it shows up in the damos as 32 instead of a 0 like one of the previous guys said. Is it incorrectly defined or is it like that because of DSG?

Mine is a 0 ... Scirocco R DSG

Mine is 32. Pops working CWSAWE=32 in 2011 GTI MK6 DSG.

Do you changed to "1" or work in "0"?

So I tried it out yesterday, got nice pops and bangs.
Changed KFZW to -20 at 2 lowest loads above 2000rpm
KFZWMN to -25 at the same load cells rpm
KFZWOP to -15 at those load cells and rpm
KFNWEGM to 7000rpm from 50degrees

But one thing is there was 4 KFNWEGM maps. If I change all 4 I get the loudest pops and bangs. I tried changing 1 at a time and leaving the rest stock but then I only get a few small pops when I let off the accelerator in all gears. The maps are all named the same so I don't know what the difference is between the 4, anyone have an idea? I was hoping it was for different gear modes, cos I've seen some people say they can do pops and bangs only in manual and sport, but if I change 1 KFNWEGM map I get small pops in all gears

easier way:

0010:0000 = 2:0

Please, help me

How are you trying to compare?

It’s hard to find constants(

Here’s a clip of my version on a Volvo:

https://youtu.be/o2d87zx0xFQ

Is there a common setting for flames?

This thread.

OK, how many negative degrees do you think would be ok for getting bangs?

I ended up using -24 on lowest load row 15 to 20 from 4500 RPM to nmax.

I used -30.

I used -20 in KFZW but you also have to disable the fuel cut on overrun to get the bangs

https://youtu.be/AIjPuucCXJU

Finally working!

Only KFZWMIN moded, stock KFZW & KFZWOPT.

HI thanks to all i get pops and bangs! a lot! but i also have a lot of black smoke

Of cause, you're dumping unburnt fuel into the exhaust.

yes i guess but on idle if I push throttle a little bit i have balck smoke, maybe too muchs s on  KFTVSA

What is KFTSVA set to?

POST NUMBER 2:

Also mentioned several times in this thread:
CWSAWE negates the need for a depressed clutch.

swsawe = 0

kftva= 2.8 between 300 and nmax on 60 and 80ºc

KFNWEGM= 5080(maxvalue) on 60º and 80º

BR and thank you so much

I wouldn't alter KFNWEGM, but every man his taste.
But I assume you have close to zero engine braking and poor fuel economy?

You also need to set CWSAWE=1 if you want it to work without having to press the clutch.

I have 0.5s total overrun, and I get a nice pop and gargle on shift with a heavy foot, and a gargle on normal driving.

Read the thread again until you understand what you are doing to your car.

yes cwsawe =1, I let kfnwegn stock and now run better.

sorry for my reply:

soo you only changed KFZWMIN and nothing else ?
and which parameters did you enter ?

can i done this to my audi a6 4b c5 2.7t 2001 ? i think its a me7.1
done only ms41 before in my e36 with overrun and other things
(if you need help with your ms41 in your e36 i can modify your ecu bin if you can help me with my 2.7t [for all in this forum] )

He did it on MED17.5.
I don’t even think what he has done if possible on me7.5 let alone 7.1 without code change and a new min timing map for ac on/off

Did anyone get to the bottom of this? All the logs of over run I've taken do this. Big junpys between BTCD and ATDC. Would be good to get it in ATDC for as long as desired. More chance of decent bangs/flames i think

who knows where is CWSAWE in 8N0906018J file? Thanks

Try @11211 for 8N0906018J_360314

thanks, I'll try after weekend and report here

hello! do somebody know map adress where to disable fuel cut in 1.8t agu engine ( m3.8.3 06A906018CG ) ? or maybe some idea to gargles in deccel like this: https://www.youtube.com/watch?v=ygeEnzkTPMQ

Hi.
I try to get some gargles but something strange happens.

I modify KFZW, KFZW2 and KFZWMN_0, KFZWMN_2 to -15 degree

If i raise rpm above 3500-4000rpm ecu start asking max load and 15% load about 0.2sec cycles.

Why ecu start asking max load?

Have anyone activating and deactivating Bang and Pops with Cruise Control?

I am.unable to find KFTVSAKAT in this file posted

update there isn't a map called that i got it to work as well

what about the me7 with narrow band, there is no CWSAWE which map should i use either?

how do you get it to gargle, i have the pops but the most it will pop is twice, and what RPM is it best to do it at, i currntly have it set at 2500 rpm  at the top three load lines

Are you at the top load line when you lift?

When you say left off as in shifting this is how my map looks and I get it in a light load when shifting

I thought you meant the top (maximum) load line.  That's correct.  That's not the only map change though.

I have changed  KFNWEGM and KFTVSA and  I set   CWSAWE to 1 i don't think med 9.1 has KFTVSAKAT  what other maps are needed?

Can someone help me to find the right solution for my Audi TT 2.0 TFSI S-Tronic 200hp BWA?

I'm interested in this, too.
Heard that someone activated/deactivated it over the Climatecontrol

Can easily be done by a small assembly function, essentially a map switch. Either switch the whole set of maps or maybe just CWSAWE flipping could work.
Link it to sport mode or whatever.

I've been trying to learn how to link and create assembly functions, just not having any real headway with it.  Trying to find that "ah-ha" moment where it all begins to click. 

I've got it perfect on a guy's wideband TT BAM Engine. Changed KFZWMN to -37.5 @ low loads from 3-7k RPM. Changed KFZWOP to x-20 at low loads 3-7k RPM. Simple changes, great results, link here https://vimeo.com/268298778

can you show a screen shot on your maps please?

He literally told you the numbers?

Yes I know, I wanted to double check my map and see if I have it correct, I got the pops but nothing like his video

i had to fix my KFZWMN my load part was wrong, now i have corrected it and will try them numbers.

as before my X axis was dinfine incorrect as you can see a few post back.

Why not post up what you've changed?

Tried it and it worked much better then time when I edit KFZWOP

It works different on different engines and ECUs of course they have different operations sometimes. However changing KFZWOP is important since the kfzwm chases kfzwop and if kfzwop is too high the pops and very low because kfzwm will go after kfzwop and go positive.

ahh okay that make since and i am on med 9.1 BPY engine

Hello all,

Can anyone tell my name of maps in german ?? for 8N0906018AE.

THX

Is overrun only possible on turbocharged cars?

Is it possible on 4 speed auto cars?

I'm trying to figure out if it's possible for a 2.0L 8v engine.

I've attached my bin below, if anyone has any map locations or a full xdf, It would be greatly appreciated. Thank you

For people who can't find CWSAWE, here is a trick. Go into a bin editor like 010 Editor, search for component nr in ASCII search mode and search for 20vt. Then just 1 or 2 lines under the component nr of your engine the first 00 or 01 will be your CWSAWE, usually 2nd or 4th column. Enjoy.

Good Evening,

can anybody explain, what B_dsls and B_desu stand for? I don't have the FR for MED17.

My Goal is to Map Pop&Burble on AC by using the delta RPM trick, but it does not work. Since CWSAWE=32 worked on DSG Cars, these bit switches mustn't be necessary for my target, a manual car. Don't want to try it without knowing what it will affect or what they are used for.

Thanks in Advance!

After some further search on Google, i found out that B_dsls stands for "diagnose sekundärluftsyttem" means secondary air system diagnosis active and B_desu is a request for regeneration of NOx-Cat. Just in Case anybody else is wondering about the same question.

NOx-Cats and Secondary Air System are not installed (Euro 4 Car). Anyway, even if they were, B_dsls and B_desu would not be requested all the time (i guess) so Bit 5 is "%MDFAFI" but seems to be the key difference in my opinion. If i find out what this bit it affects, i will have another try and report.

I've been playing with this the last few days and now bored of bangs.

I want flames.  Lots of flames.  Minimum ignition angle is -24 and ZWOUT follows during lift off.  Lambda actual goes lean (+1.4) but requested is 0.93 (from lamfa).  After about 1000rpm (from say 6500 engine braking to 5500), injector pulse width lifts to >2.0ms and lambda drops to overshoot requested.

I brought TEMIN up to 2.0ms but it's caused cruise to be 10:1 obviously.  

I think I'm getting confused and can't really find concrete evidence on what creates lift off flames.  You need fuel; but I'm unsure how dump fuel on lift.  Not sure if -24 is enough.  I've walked around various numbers but not really found a sweet spot yet.  Rich?  Lean?  More advance?  Less?  Table tops at -96.

Change variable cam tables so you have lots of overlap on overrun.

Good idea!  Will try!

Hi guys,

i'm currently working on pops / bangs on a Corsa D OPC / VXR with ME7.
- I lowered ZWMIN to -50° everywhere
- KFTVSA & TVSARL to 2.5s everywhere
- NWENG & KFNWEGM to 0rpm everywhere
- I set CWSAWE to 1
- Tried to disable the Tip-In functionality
- Raised FWET & FWEHT by 0.5 everywhere

Got this running on an Astra G / mk4 Z20LET by simply changing ZWMIN. Not working on this corsa.

Just a little bit of gargle. I'm guessing there is too less fuel, maybe because of these small injectors. So what are your guesses and how to raise the fule amount?
Was thinking about using LAMFA for this.

Cheers

My understanding from the overrun cut function is that KFNWEGM is the RPM-Limit underneath Overrun Cut is forbidden. So for example if you change KFNWEGM to your Rev-Limit, Overrun Cut is forbidden for every RPM and the ecu will inject&ignite all the time. You actually made that overrun cut is only forbidden for only a specific time (which does not only depend in KFTVSA! Read this thread, there is an explanation about the waiting time before enabling overrun cut).

-50° KFZWMIN seams very high to me. This value depends on the car, but most people have success on different cars with ignition angles from -20° to -30°.

@n14

Ive been reading the whole thread the past few days, so i know what you mean, but: The name of this map is called "Wiedereinsetzkennfeld" in german so its the rpm at which the engine starts to re-fuel after SA fuel-cut, right? If it is, wouldn't it be right then to set it to 0?

Additionally, i tried setting it to 7000, but also no effect on the corsa. Normally I'm working with -40, as in my astra, but as this didn't seem to work, ive been trying this out.

My guess is, that, probably not only in my case, the Tip-In affects the ZWMIN with the ZWSPAE. I tried to overrun this by simply setting everything in ZWSPAE to -40° but the gargles are only getting a little bit louder. Measured with an obd-reader and its -30° when deccelerating. So the angle is late enough. Thats why I'm thinking LAMFA is the right choice.

Am I wrong? I attached an Image of the LAMFA map. Is there anything wrong? like too little injection or so? LAMFA is original currently. Was planning to set first row to 1.

Adjust that axis.

0-70% has fuel above 1500rpm.  No need.

Are you German, Ulf?

From my point of View "Wiedereinsetzdrehzahlkennfeld" means the RPM Tresholds wenn ECU starts to Inject and combust again after the engine speed dropped. For Example:
When you accelerate until lets say till 5k RPM and you press Clutch and release the gas pedal, the engine speed drops while (after some amount of time, defined by KFTVSA and some other influences) overrun cut is activated. When the engine speed lowers under the RPM given in KFNWEGM, overrun cut is deactivated again.
In German you would say " Es kommt zum Wiedereinsetzen der Verbrennung".

I think, if you set this value to zero, you will never force to disable the overrun cut, while if you set it to rev limit rpm, overrun cut is always disabled because you always stay underneath the threshold for "Wiedereinsetzen".

I can't help you with the other Questions, sorry.

@adam-

So you mean to set the first row to 1? If so, i will try if its working and report.
Is the range from 0-70% for decceleration?
Do you think the tip-in has nothing to do with it?

@n14

Yes, I am.

The only thing I can say about this is that ive got serious pops and bangs with KFNWEGM set to (original value) 1600rpm everywhere. I tried 7000rpm and 0rpm in the corsa ecu and nothing is working. I will test this on my astra with 7000rpm to check if this works.

For clarity:

I just changed my username to opctim. ulf91 is a name ive been using for years for a reason I don't quite remember, so i guess its time for a change.

No, it's pedal position.  So cruise is always rich.  No need.

From my opinion you also should at least try more earlier angles, like -20°. Angles from -18 until -22° work good on Mini Cooper S R56, for example, other users had something around -20, -25°.
Of course TFSI,BMW and OPC engines are barely comparable, but they are both small package concepts with short exhaust manifolds and the cat directly behind the Turbocharger. From my understanding, for Pop&Burble you need enough combustable Fuel/Air-Mixture at the right place in the exhaust system.

I don't know which engine you are driving in the Astra, and i hope i don't get you nerve while writing this another time, but you might give earlier angles a try.

Ok. Will try on the corsa.

I'm driving an Astra G / MK4 OPC / VXR with the Z20LET and ME1.5.5 equipped. -40° results in lound bangs, while -20° only gives me relatively quiet gargles.

No problems with the astra. Already programmed a hard cut limiter with, lets say, 30 - 40cm long flames from the exhaust when running into the limiter. (Kat-Killer, for sure. Did this with decat.)

So, back to my question:

Is there a way of enlarging the amout of fuel injected while deccelerating? TEMIN? TEMINVA?

I'm playing with KFKHFM and KFLF just now.  Going to try bumping KFLF UP to see if that'll put more in.

I tried cam switching too; AFR now goes super lean on lift (which makes me think it's now getting air) as before it was just going rich but still no flames.  So I'll add a bunch of fuel in with KFLF.

Timing values, I'm still undecided on too.  -30 at the limiter sees good flames but could be better I think.  Overrun wise I'm struggling, can't find that perfect spot yet.  Currently at -27 tapering down to -21 as the revs come down near 3000.

You will not get any results on your Corsa comparable to your Astra with original Exhaust System and Cat in Place anyway  8)

The corsa already has a 3" pipe. Pre-Cat removed. Main-Cat still in place. My astra is also banging with cat installed and 2,5" pipe.

So you achieved to enlarge the injected fuel amount while deccelerating with KFKHFM & KFLF?

I'm trying.  I need to get out and log.  It's too warm just now (32 degrees), so I'm drinking rather than logging.

I feel with you mate. Similar temperatures here in germany. Glad i've already installed my 450mm intercooler  ;D

So I changed a few values and achieved to increase the injected fuel amout while deccelerating. Did this with CWESWEZ, FWEMXT, FWEMRFA, FWEHT and FWET.

But: Something is limiting my ignition angle. No matter what I do, its not going beneath -27°. I know that i need -40° to make it pop.

So, what is it? I already set KFZWMS to -40° everywhere. What limits my angle??

U don't need -40 to make it pop, I'm running 25 degrees on BAM ecus and they pop all day (no mods required to CWSAWE or any other map) which is weird and I am NOT sure why this particular ECU reacts so well to changes... all k03s ECUs need to change many maps with not much effect... One thing I can say - best ECU for 1.8T is the BAM ECU i've had easy success with small changes on these cars.

Logs?

On my BAM ecu I only set CWSAWE to 1, set entire KFTVSA map to 2.5, set entire KFNWEGM map to 8000 and KFZWMN from 2000 rpm the 2 lowest load rows to -37.5.
Oh and LAMFA from 2500 in the lowest row to 0.74 and it gargles and pops, not super extreme but its loud enough to hear.

You can play with KFZW in the lowest 2 rows to burn more into exhaust which gives a louder poppin, also you can play with fueling.

I've never touched any of the maps you're aiming at opctim, so I dont think you should touch those maps to achieve what you want.

I don't exactly know what you did, but I think you can also achieve easily to have more fuel when you use:
- RLLAMMN (RL-min Schwelle zur Anfettung wegen Brennbarkeit) -> Threshold of RL for enriching for better flammability
- LAMRLMN (Lamdavorsteuerung bei rl < RLLAMMN zur Verbesserung der Brennbarkeit) lambda-value when you are at lower RL than in RLLAMMN

regarding the ignition angle... see the first few pages of this thread...



here is the answer:



greets

This thread has been a very very good read! Thankyou for the info!

Unfortunately I don't have a very good definitions file, so looked at a file for a Cupra with pops & bangs already added on ECM at work after hours.

I saw the timing base maps had all been changed to -30 degrees on the lowest load cell, and understand that changing the timing = pops.

Then there's an 'optimal spark' map that had been reduced -20 degrees in the same areas. I changed these to the same values but couldn't get it to work.

When I went through the files on Swiftec I spotted two maps i had missed that looked very similar although in a different place;

1C581D - half of this map seemed to be set to 80, and the rest to 0 on both the Cupra and my car, the pops mod had been set to 255 - reading through here, I assume this is a fuel cut delay map, and this is measured in seconds, and setting to 255 is just setting the entire table to maximum value?

1C9C42 - This had a value of 800 on the ori, and 0 on the mod file - there were four values in a row, identical in both the cupra file and my file. I think this is the fuel cut?

With these changes done, it pops loudly between gearchanges at high RPM (hence thinking that 1C581D is infact one of the delay maps discussed in post 2), and bangs at the top end of the RPM range. I left timing stock below 3500RPM so it wouldn't make any extra noise in traffic.

Can someone confirm what these two maps actually are? Have attached ori.

Many thanks!

You can place this file from Cupra here.

I still dont know why people insist on changing KFNWEGM  :-\
The is no need is no need to change it.
And when you do like most people do and max it out in all fields, you loose engine braking.

All the maps i touched to get a nice deep gargle and occasional pops on everyday driving.
And bangs, popping and gargle on hard driving is:

CWSAWE
KFTVSA
NGDNSA
ENSAKHG

Last two are ME9.

NGDNSA & ENSAKHG?

They are also present in ME7 :)

Never heard of them and no defs came up like they usually do for nef.  Interesting.

What do they do? :)

NGDNSA is RPM gradient for fuel cut off.
ENSAKHG is a config for when it is allowed to do overrun :)

BBSAWE is a fun module  ;D

Yeah, I was lazy when I replied, went on to Google because I hate people that don't.

I'll check it out!

What did you set NGDNSA & ENSAKHG to I found the maps but it looks like there all 1x1 maps

ENSAKHG is a config bit. And I think I set it to 63 to allow overrun in all situations.
NGDNSA is set to -5120 or thereabouts:)

Sorry, but asking this to clarify :P

With NGDNSA am i correct in thinking that it'll cut fuel below 5120rpm on over run?

If so then that seems a better way to do it rather than using kftvsakat as I am now to disable over run fuelling below a certain rpm.

As I understand it, it is the speed gradient (RPM/s) where fuel is cut off.
As in if you decelerate at with 5120 RPM/s (hence -5120), fuel is cut off.
Anything above that, fuel is on.

i am noticing i am getting rev hang for about 2-5 second would the map CWSAWE cause this only hangs when i have over run enable

My KFNWEGM looks like this, I think the first two rows with the Values 100000.0 are wrong ?
Has anyone a Picture from his KFNWEGM that I can compare it to mine ?
I think the Map is not assigned properly in my XDF.

(https://www2.pic-upload.de/img/35766220/Unbenannt.png) (https://www.pic-upload.de)




Edit:

And has anyone found a possibility to put that gargeling on and off by pushing a special Button in the Car ?

Edit2:

So I flashed my ECU with the changes in the following Picture.


But it dosent bang between shifting, it only bangs sometimes when I am in Overrun but only when I hit the gas shortly.
With 37.5 degree it is the same, so I put it a littlebit back.

Now I am not sure If I should test it with more Fuel (look at Lamfa at lowest line in the Picture).
But I think the Problem is like somebody wrote earlier in this thread, that there is not enought Air that the fuel can not explode.

(https://www2.pic-upload.de/img/35768473/Unbenannt.png) (https://www.pic-upload.de)

Read the thread again. Seems like you missed a lot of important things.

I read the whole thread again.
The problem is, everybody do different stuff and for some engines it works for some not.

But I think I disable it again, my Cats would be glad about it!

First of KFZW shouldn't be changed and your LAMFA axis looks funky.
And your changes in LAMFA isn't needed, they do not apply on overrun.
And the whole KFNWEGM thing, I still dont get why people use that way.
But yeah, your KFNWEGM doesn't look right.

Me7 has a hard limit at -25° ignition, so anything below that won't make a difference.

How do you stop the revs from hanging during shifting?

@birchbark506
Are you shure there is no highly positive angle in KFZWMN? This is something that could cause this.

@KasperH
In my case, I was able to remove that limit by modifying KFZWOP. There is a delta between KFZWMN and KFZWOP which didn't exist in earlier ME versions (like 1.5.5).

Are you referring to the negative timing limit?
No way around it, its hardcoded.

Yes, but in my case it works. Was logging this and angle goes down to -40° when deccelerating. Bangs are loud as well. No problems with this since i changed KFZWOP.

How would I log just when I shift it takes about 2 to 4 sec before I can let clutch out to grab next gear, if I shift to fast it's to high rpm to shift

KFZWMN is set to -40.500from 3000rpm until 7200rpm

I would like to see logs of this?

Please clarify what you mean?
If it's related to the rev hang, just turn on logging and drive around and make sure the revs hang.

Okay, I'll just log the rpm while driving around is there any vavle block specific to log?

So I've changed KFZW back to default now, KFZWMN and KFZWOP are now -24.7500 in the first three rows and KFNWEGM is set back to default cause this "no Motorbreak" fucked me up.
I didn't changed LAMFA in the first row, was just and Idea.

But on shifting there are now bangs and pops, sometimes when I am at ~ 3000 UPM I have one or two Pops but they are very rare.
I don't now why that didn't work properly on my ME7.1 (S4 B5), I got RS4 Downpipes without precats and 200cell metalcats also a 2.75 inch FOX Exhaust without presilencer, so I think I should hear the Pops loud enought.

That is not true.

I‘ll look forward to doing this.

Maybe there is a limit because your TIPIN config bit is misconfigured?


What I‘m currently trying to achive is that there are loud, single bangs between gear changes. I achived this (partially) by setting KFZWMN to -40 degrees in higher loads. This seems to work, but not constantly. Obviously, it works best at ~3000rpm.

Some ideas why?

It's the same on my Car.
If it works then at ~3000rpm, but its very quiet if it pops at all.
At gear changes I never heard anything.

I set it from 3000-6000rpm and from 0-150% to -40degrees.
The bangs are nearly uncontrollable then, but there are loud bangs while changing gear.

Here is an example of it (Not the ALS, I mean the bangs when shifting)

https://youtu.be/P8mEzBfL2AY

This is actually what I‘m trying to achieve.

Oh, you want no lift shift ?
Thats another story, look at this:
https://www.docdroid.net/vffm/me7x-lc-nls-rev003.pdf

I know this PDF and basically yes, but this is not going to work out because I have a ME1.5.5 ECU in my car. Pretty similar to the ME7, but not the same.
Already starts with the problem that it doesn't have the FTOMN map.

will that NLS work on med 9.1?

just for fun.. anyone would be interressed with an unlimited overrun hack ? nop the jump if time > 2.55 (FF)  ?

=P

You mean like using KFNWEGM so that the fuel cut is disabled all the time?

What about raising TEMIN? If lamda is right, this could enlarge the chance of bangs between shifts, am I right?

Or, depending on injector size, you could royally fuck your idle.

So, how to enlarge the injected fuel amount while deccelerating then?
LAMFA is not an option, this is used when accelerating, too.

Here is a summary with my changes:


If you didn't want a full overrun fuelcut, let the last line of KFNWEGM at defaults.
KFZWMN I set at minimum loads to -24.750 and KFZWOP I set at minimum loads all x-20.

Now you can hear the bangs very good, the last time I changed accidentally the lamfa at minimum load, I thought I didn't saved it

https://youtu.be/X1W30ZdW40M

give RLLAMMN a look.

Unfortunately, the ME1.5.5 doesn't equip this map. I'll give LAMFA a try, even though I don't believe this will change anything about the bangs between shifts.

Okay, I'm stuck here.

I've had another look at this file, this is the version i currently use - So in theory should have pops above 3500RPM (the idea being to be able to drive in traffic without a lot of noise, but to still enjoy the pops when driving hard)

It pops like crazy above around 5000RPM or more, huge bangs on gearshift etc- perfect! Someone mentioned earlier in the thread that there was another fuel cut map, this is ME9.1 and not ME7, but I wonder if perhaps I've missed another fuel cut map as despite my timing changes from 3500RPM i still get nothing below 5000RPM. I did also try a file with 4000RPM timing changes, but this didn't seem to make any difference at all.

Attached ori, tune and tune + pops. Any hints/missing maps would be greatly appreciated - I don't have a damos, only a very rough XDF created from a partially matching Golf GTi damos, and notes from ECM driver.

try this and report , it is your ori file only with pops bangs changes needed

Spacey3 did you solve this thing? Mine timing did same thing.

Changing KFZWOP on top of KFZWMN/KFZW works just fine for me.

And then you didn't have this oscilations in timing? I have KFZWMN all on - 40 and KFZWOP/2 first 2 row on - 24 so I need to change KFZW too?

That’s right, yes :)

But what with idle? This isnt affect it?

Well, you need to miss out the idle areas obviously... just anything above 3/4K or wherever you want it banging

I'm stupid.... You're right. Idle isn't on 2k rpm and higher. But my 2 load row is 9.75 and 20.25 so if I change it over 2k rpm I can drive with part and low load safe or it cause weird timing? I ask because You made changes so it may help me very much.

Hmm i am tu Stupid or my WINOLs is damaged, i dont find the right Maps can anyone help me ?

These are the bangs I‘m trying to achieve:

https://instagram.com/p/BnZS_7Sg_ok/

Actually, it works sometimes, if KFZWMIN is set to -40 at higher loads. But only sometimes, its not really convenient. Any ideas? Raising LAMFA didn‘t do the trick.

Just by thinking about it, is it possible to cut the ignition on clutch press?

Thanks! This file has a lot of changes - I'm trying to understand them all, won't get a chance to get at the kess again for a few days yet! Looking at your pops file, I notice what I thought was the fuel cut hasn't been altered at all - I'm now wondering what exactly I did change, and what was changed on the Cupra file I based this pops tune on. Some of the timing changes look a bit odd on 0x1D9B92 though - I'd changed very minimal sections, whereas you've changed the entire lower four rows, and then a chunk at mid-low rpms under high load?

I did log my tune, I hit the requested -30 degrees of timing pull, however the fuel cuts off still.

Have attached a few interesting files that might help people out. Ori, Tune, Tune with Pops, Datalog of tune with pops, and a work in progress tunerpro XDF.

I think your problem either comes from CWSAWE or CWDMFAB. (see attachments)

Agreed, everything I've read here seems to point this way - any suggestions on how to find?

All the VAG ME9.1 2.0TFSI files have that exact same cluster that I adjusted @ 1C9C42. 

pls someone can help me find CWSAWE in this file?

Can try 0x15475

Let me know!

@Iain

My guess is, that injection while deccelerating is disabled, because your torque dampening (Lastschlagdämpfung) Bit (first) from CWDMFAB is disabled.

Could also be DENOX in CWSAWE bit 1 since its at TFSI.

Yes, could be. But the first bit of CWDMFAB completely disables injection.

@Iain:
When releasing the throttle, at, lets say 3000rpm, is there a rough engine break or not?

P.S.: In one case that I experienced, the car only started banging at -40 degree KFZWMN.

dont work

What parameters do I need to change to achieve this on a Bosch Me1.5.5?

Pop and bang is already mapped in but I want to adjust it, but I have no idea where to look at.
I have read ZWMIN, but what more?

On a ME1.5.5, check for CWSAWE, CWDMFAB, and set KFZWMN to -40 degrees at the required points. In this ECU, there is noch delta between KFZWMN and KFZWOP. So these are the only things to change.

Oke thanks, this really helpfull! Now I can adjust it atleast.
I will reply how the results are over a few hours.

Here’s my way of implementing on Volvos. Switchable via Four-C chassis settings.

https://youtu.be/kqPC38fQ7FA

Now THAT is cool!

hello  :)
And how about MED9.1. I have a TT 2.0tfsi S-TRONIC. I have set KFZWMN -30º from 3000rpm to 5500rpm but only follow KFZWMN between 4000rpm and 5000rpm and pops are very very quite.
CWSAWE is set to 1.
KFZWOP is not tuned
I can't search KFTVSA. Comparing with other 2.0tfsi, i think that my .bin doesn't have KFTVSA.
I am only looking for pops when I leave the throttle.
Attached a log --> look at the regions with -30ºC an 15% engine load... second 53 in the log

My exausht configuration is 3" decat. Only mount the rear original silencer.
Sorry for my english, i am from spain

hi
i ve read all pages many times, but i can't do successfully this funny mod.

i've modded my 06A906032DR like this:

KFZWOP x-20 on 10-20% load from 3000rpm to max
KFZWMN on -24 for first three load rows from 2520rpm to max
KFTVSA on 2.55 from 3000.0
CWSAWE on 1 to address 011211

i can hear some only small pops under 3000rpm (confused)

apprecciate any help.

No rough engine braking to report - it seems perfectly driveable with no odd behaviour other than perhaps a little stutter at very high RPM and light throttle inputs (I assume because car is hitting -30 timing not +32 and interpolation is doing weird stuff between the cells. You really do have to try to make it hit these issues though!

How do you identify the codewords in a file correctly? I found CWSAWE by looking at other similar files  110 004 003 032 005 - there was an identical section of data in roughly the same place on all 2.0TFSi stuff I looked at, and the Cupra pops file had this modified so I assumed from what I had read that this was probably CWSAWE.

So if I understand correctly, CWSAWE stock is 00000011, and modified is 00000000

So as per below, what I (should) have changed is to make the file so that fuel cut is always delayed, and b_denox does not disable fuel cut - everything else appears to already be set to not switch off the fuel;

The function can be configured via the internal codeword CWSAWE:
+ --- + --- + --- + --- + --- + --- + --- + --- +
Bit No .: | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
+ --- + --- + --- + --- + --- + - + - + - + - + - + - +
| | | | |
| | | | + ---------------------> 0 = Push-off is only delayed at B_kuppl = 1
| | | | 1 = fuel cut is always delayed
| | | |
| | | + -------------------------> 0 = B_denox does not disable fuel cutoff
| | | 1 = B_denox blocks fuel cutoff
| | |
| | + -----------------------------> 0 = B_desu does not disable fuel cutoff
| | 1 = B_desu blocks fuel cutoff
| |
| + ---------------------------------> 0 = B_dsls does not disable fuel cutoff
| 1 = B_dsls blocks fuel cutoff
|
+ -------------------------------------> is used in% MDFAFI

Or am i making a horrible mistake in translation  ???

Where can I find a chart showing how the MED9.1 ECU operates, I've seen the diagrams - rather like a flowchart, but I'm not sure what they're called. Perhaps if I study this I can better understand how/why this doesn't work 100%?

Thanks for all the help!

Try this, and add cwsawe=1 if its required.

Hi, trying to find CWSAWE on 018N ecu, comparing to others I think it shlould be arround x15397, can someone confirm?

Thanks. Now it s OK, and I see where s my error.

Hello, can someone please help me to find KFZWMN on 8E0909518AQ BFB?
Thanks.

All right, looks like 0x124E7 is KFZWMN_0_A and 0x125BF is KFZWMN_1_A

Unsure if helps anyone, but have attached a map pack from here with a few fuel cut maps for the 2.0TFSI.

KFTVSA, KFNWEGM x3 are all on there.

MK2 Leon FR BWA
HW: 0261S02113
SW: 1037386675
Engine: 2.0l R4/4V TFSI
SW upg.: 1P0907115   0040

For fuel I used Winols

For pops above 5k, set KFTVSA as per image.
For pops ALL the time and melty cats/exhausts etc leave KFTVSA alone and set all the KFNWEGM maps above rev limit.

For timing I used Tunerpro, specifically a few maps from ECM on it.

-20 to -30 ignition seems to work best. Less timing doesn't make it any louder, and any more starts to make it not pop.

I've attached the XDF i used for this too, and a screenshot of what I did to get it all to work.

Spark advance correction map - set to -24 in low load high RPM areas.
Spark advance basemap - set to -24 in the same areas. Repeat changes across all six.

I have got my A4 B7 TFSI (BUL) to pop really nicely using all the info on this thread. However doing so I have lost engine breaking. Does anyone know how to retain this?

not use KFNWEGM

Could you please shown us what was the error please?
Because I have a MED9.1 Dsg and I can't get pops...
I have changes:
CWSAWE (set to 1)
KFTVSA (2.55 from 4000 to 6000)
KFZWMN (-30º from 4000 to 6000 rpm)

Is it necessary KFZW/WOP really?
I don't want pops all time that's the reason I don't modify KFNWEGM.
Am I in the right way?

I have got pops!!. My problem was CWSAWE... I had it in the wrong address..
Interesting question:
Why from 4000 to 5000 rpm the ignition follows KFZWMN and above 5000, it's follows KFZW?

Has anyone done this in ME7.1.1 3.2VR6?

Hello guys, I have successfully implemented this on a 1.8T ME7, but now I have a MED9 on an audi TT 2.0 TFSI (car has turbo back exhaust system with 3inch downpipe amongst other mods...)

File is 8J0907115 (0261S02084) 386455

I have managed to find a few maps already.

I was wondering if someone could confirm what I found and help me find the rest ?

Here is what I found :

1CA0A9 : CWSAWE
1CD3B0 : KFZWOP
1D2340 : KFNWEGM_0_A
1D2368 : KFNWEGM_1_A
1D2390 : KFNWEGM_2_A
1D23B8 : KFTVSA
1D9D06 : KFZWMN

Thanks.

I have an Audi tt 2.0 TFSI.
I have changed:
CWSAWE
KFZWMN
KFTVSA
KFZW
KFZWOP

For me, the best is -17.5º on the two low loads columns from 4000rpm to 6000rpm and 0.8seg in KFTVSA.
I don't know why the ignition follows KFZWN from 4000rpm to 5000rpm but above 5000rpm, it follows other map (KFZW i think). This is the reason why i have modified kfzw too.

What about KFZWMS  KFZWMNHK KFZWMNST? I edited it too

Yes mee to. Kfzwmnhk no because is for catalyst heating. mnst, and ms yes.
I have changed too only the first column (10% load) un kfzw and kfzwop --> -18° ignition.

Hello all,

I've been able to implement this function with different settings.

I am now trying to activate this function with cruise control or A/C. I tried the combination with DNWEG (engine speed fuel on with AC) but without success. Does anyone have tried something similar?

How can I implement this function or change some relevant factor to activate fuel on through an extern button?

Custom code.

Hello, thank you for your reply ?

Could you post some screens of what you did ?

Thanks.

Thanks for the Input. I believe that´s something that I can´t do just following the Funktionsrahmen...

However this funktion is also connected with AC control. Is a solution changing the standard code anyhow possible?

Yep, I

anybody using KFLAMKRL for flames???

Fueling based on knock?

lol

Well when I accidentally found it in my file while I was extending my definitions I only seen “enrichment on ignition retard” in the description and the axis seemed like they’re in load to rpm. So I was thinking maybe that’s a place I could add or take fuel in that area.. otherwise I have no idea what it’s for..

And reading the S4 tuning wiki is out of the question?

Can anyone help me find CWSAWE and KFTVSA in this file?

look at:
CWSAWE 1C5A54 1x1
KFTVSA 1C5A69 5x8

Thank you, already added in my definition.
Can you help me with this topic?

http://nefariousmotorsports.com/forum/index.php?topic=16076.0title=

Hello all,

I have successfully implemented this function on lift off condition.

Now I am looking to achieve some bangs during gear change with dsg gearbox. I keep hearing some cars with a loud bang on chear change. Does someone already done it?
The idea to do it should be similar, retarding the ignition and letting fueling as it does standard during chear change event.
There are a few ignition maps only for gear change but I couldn't achieve this effect yet. Maybe a different ignition angle is needed for this.

I appreciate any input!

Thanks

I tried the same on my 2.8 VR6 24v MK4 AUE. Managed it to disable the fuel cut, but it wont do the ignition retard. Did the definitions on my own. Maybe I missed a map or defined something wrong.  :(

I changed the following maps:
CWSAWE at 114E9 set to 1
KFNWEGM at 195DA set last 2 columns to 6480,0 rpm
KTVSA at 19602 set last 2 columns to 2,4000 s
KFZWOP at 11777 reduced first 2 rows from 2520,0 to 6520,0 by -10 (also tried -16 but no success)
KFZWOP2 at 11827 same as KFZWOP
KFZW at 1230F same as KFZWOP
KFZW2 at 123CF same as KFZWOP
KFZWMN at 120CD  set first 2 columns from 2520,0 to 6520,0 to -18 (also tried -28 but no success)

I attached my original and modified .bin files. Would be grateful for any help.  ???

Hello,

can some one help me to add pop and bangs to this ecu? I cant find KFZWMN map, maybe this ecu dont have it?



Thanks in advance.

There's 2 maps that look like KFZWMN at address E42D3 and E4393, KFZW follows just after.

I think at those addresses are:
E42D3 - KFDWSZ - delta Zündwinkelkennfeld für selektive Zündverstellung
E4393 - KFDWSZU - delta Zündwinkelkennfeld für selektive Zündverstellung bei umgeschalteten Saugro

or i am wrong ?

If you're looking for big bangs while shifting you want ign cut and no fuel cut (many times used in race cars with dog boxes), but I dont think its a good idea doing that for a DSG box, what I know is that they use ign retard for shifting usually.

Hello, thanks for your input.

You are right, this function is partially available on the Stock ecu since there is a 0.8s fuel cut delay which is the time for gear shift.
My idea is to use ign delay to achieve this. I have made some experiments but without success.

There are a few extra maps for gear change that I changed to around 20° btdc with no fuel cut.

Maybe someone has some advice.

I keep gear dsg cars with this function so I know it's possible

Hi,
Can someone help me find CWSAWE in my bin? I've built a mappack for tuner pro which is quite good. I think I found cwsawe, but I'm not very sure of it - can someone confirm it's fine?
Thanks,

I've trued all 00 bits after ecu number.... none did the trick.
However, I'm getting nice pops on 1st and 2nd on overrun, none in 3rd 4th or 5th. I get some pops though on downshifts from 5th to 4th and 4th to 3rd....
it's possible this bin is missing this function though...
I would like to have some pops on heavy upshift but I guess that requires nls right?

Have you checked your ignition timing on the moments you´r expecting the pops?

Timing is exactly how I want it... I get the expected results. My problem is that my "poor" ecu is missing these: cwsawe, kftvsakat, tvsabte, tvsag0
So the only leverage to achieve my goal is timing and kftvsa...

I'm in trouble too, I get some bangs, but I need to start the foot lightly on the accelerator, very difficult to find the TVSAG0 and the CWSAWE, Audi A3 1.8T AGU M3.8.3 06A906018CJ

anyone able to help me locate KFNWEGM in this file

http://nefariousmotorsports.com/forum/index.php?action=dlattach;topic=4445.0;attach=28860

No need to modify that map for pops & bangs

Tried this to my car.Changed a few maps and have good results but not always.Sometimes i dont hear bang, sometimes is really good.What i want was bangs after 3k rpm. What i do is:
- KFTVSA - Everything to 1
- KFZWMN - First two rows changed everything after 3k rpm to -30
- KFZWOP - First two rows after 3k rpm - (value-30)

I have also launch control but not made by me, so KFTVSA was already changed all to 1, i didnt touch there. I also didnt touch CWSAWE and its stays at 0. What difference will happen if i change it to 1 ? Also im searching for KFNWEGM map. Read that some people have results only with KFNWEGM and CWSAWE to 1.
My questions are is this bad for engine and turbo ? After turbo i am with straight pipe. Also i found that with these settings car goes off more often.It was happen before too from the BOV but now its more often.

Certainly doesnt not preserve turbos but it does not hurt as much as LC or ALS. Also dont change KFZWOP .. its not an ignition map.

Okay i will return previous values of KFZWOP map.Also changed other stuffs to start from 1700rpm and switches CWSAWE to 1 to find out whats the difference.

This in particular is already spreaded in this thread and also can be found in the FR.

OK I followed the other suggestions in this thread with no noticeable pops/bangs? I will give it another bash though. Thanks

Returned KFZWOP back to previous values but now pops and bags are rarely happen.Dont know for what exactly is this map but i think its affect those things

As a safety precaution the mixture will be enriched depending on how much the actual ignition angle differs from KFZWOP. So even though it does not change the ignition it will affect your so called pops and bangs as more fuel is added.

KFZWOP is a torque calculation map basically. Its to compare actual timing to optimal timing, it never used in anything aside from calculation for the ecu. It pretty much should be never changed. Find different methods to get your bangs..

Blazius, could you be more precise about this? I understand it not like this. At least for 1.8t and ME7.5 FR KFZWOP is used for zwout IMHO.

Thanks!

Had a few cars not respond to the usual group of map changes for pb until I changed KFZWOP. I remember logging ign angle, and angle definitely changed in conjunction with WOP changes.

Yes if you increase/decrease KFZWOP you actual will change too(ZWOUT is the output of ZUE module) however its not recommended. As said its used for comparsion between values in it , which mean 100% ignition angle effeciency , but later this value goes into ETAZWB , where the efficiency gets calculated based on the delta angle, for torque calculation. Other stuff like temperature, egr (where applicable) offsets it too.

Hi could some one help me find cwsawe in this file?? or some one can add pops and bangs on my file?
thanks in advance

try 0x11211

Anyone know what DNSAH and DNSAL maps do? They are in BBSAWE module.

Ok i try this method, it is working but some things i need to repair
When i lift of my foot from throttle it gets pop&bangs, but after the aprox 1 sec my iginition go from -25° to 5°
The second problem is that fuel is injected all time, it does not follow KFTVSA values
Any sugestion where to start from?
ECU is 8E0909518AH

KFNWEGM is a fuel resume map, if its set to 7000rpm it will resume petrol injection from 7000rpm to idle ...
so if You want KFTVSA to do his work leave KFNWEGM stock .

Thank you, that it is. But now i have some sort of protection. After 1.5 second fuel cut come in(it is set to 2.5 sec), and my iginion start to follow zwmnnms. Then again it goes to low values
This could be a engine protection  B_zwms, but I can't see how to turn it off, maybe KFZWMS?

Edit: i changed KFZWMS, now ignition stays at -24, but fuel cut come in too soon

go to FR and check review the BBSAWE function.

Hint (not sure if it will solve: check KFTVSA KFTVSAKAT TVSAG0 TVSABTE)

I will do more digining. It is not connected to seconds, somethnig else control fuel cut.
These are two logs
One after 3 gr. wot, and one after 6 gear run

I think once it gets to lambda=1 then ignition follows another path.

Ok, I've read whole topic, but I still need an advice :(
I want to reach something like this https://www.youtube.com/watch?v=VWH3pkD5Ru4 (it hasn't to be that agressive as the loudest one, but something like that, still don't want to flame from pipes).
In a few words, I want gargles on engine deaccerelation (without pressing clutch) :)
I'm still not sure what should I have change in maps. As far as it is MED 9.1 (2.0TFSI BWA) I think about settings like on the picture.
KFZWOP 10% row "value - 20", 15% row "value - 10".
I wonder to change CWSAWE to 1 (to use gargles without pressing clutch), or I should do not that?
Or maybe use ENSAKHG set to 63 like @KasperH did it?
Halp :D

okay so can we come to a conclusion as to what ENSAKHG is?
google translate has two definitions depending on if you put a space between katheizen. first definition is without space between kat and heizen second is with space.
1. Enable overrun shutdown during cathexis dependent on gear
2. Release Thrust shutdown in the case of catalytic heating
also how is it determined as to what value to set this at?
ENSAKHG exists in the Mbox damos address 11171

1) there is no universe where Kat heizen is anything but cat heating
2) did you bother check the FR? The bits are pretty explicitly explained there.

you got it. i'll take a look now
thanks

Well, I won't touch ENSAKHG as far as I won't be sure what EXACTLY it does ;).
Anyway, I've changed maps like on my picture above + I've changed CWSAWE. I just got 1, max 2 single pops when I let off throttle, but never on gear change, only when decelerating (and not always), when standing it does suprising 3 pops :D.
I was wondering about reduce KFZWMN to -17deg, change KFTVSA to 3.5. I don't want to make large pops, bangs or flames, I just want gargles. (And maybe rescale LAMFA 50% to 10% and make something like 0.9 LAMBDA for this value, should I?)
Is my thinking in a good way or I should do more to get  gargles on MED9.1?

any retardation on the timing map produces a nice deep bang on gear shifts and obnoxious popping on decel depending at which rpm you have it at

my issue is since the timing is retarded, the car jutters when going back onto throttle. yet to solve that issue

This probably the cause of the fluctuation between the advance and the retardation of the ignition. Log ignition to see what it does at going back on throttle.

that is exactly what it is doing. i knew this but felt it wasn't healthy so i just disabled the whole timing retardation deal for overrun

Hi, can someone tell me the maps for ME7.5 512 kb. These ECU do not have all the maps that you decide regarding the MED or ME7.5 1024kb.

are we supposed to guess what ecu you have?
post your ecu # and version

You're right.

Audi TT 1.8t
Code engine:APX
Bosch: HW 0261207030

Does anyone know the map name for fuel cut in VAG Marelli 7GV ECU? Something like a kfnwegm or kftvsa found in Bosch

Hi, im try to get pop and bang oned17.4.2 on 207 gti. Engine is loke mini jcw 175cv. I get and bang and flame in idle running but in neutral (car bloccked) i have 0 pop and some bang whit some flame. Anyone can help me on this ecu?

Many thanks in advance

Some BDE/BDF quick look locations if you're a V6 4mo/VR6 24V owner and want to save time piddling about (look at the data surrounding them if you need to close in on locations on your file if need be, but most are v similar);

Hi ! its me again  :D

I can't find CWSAWE or KFNWEGM on my file:

MED17.5.25

1.2 TSI

Can anyone help me please?
Thanks in advance

KFNWEGM is at 0x257a8a, two maps one for manual and another for DSG.
 Dont use KFNWEGM for pops and bangs , however, way better to use KFTVSA just next to it and its variations to get controlled pops. Also don't forget KFZWOP maps which are 16bit in this ECU apart from KFZW and mínimum limiters.

Thanks man, you have this Damos or MapPack?

I have a few damos for this ecus but i found them manually on your file, i've posted 2 med17.5.2x damos files here in the forum for free, check my posts

Can help if still needed

Hello,
search : TVSAG0

Hello friends, I think I'm doing the right thing, but I can't get pops without modifying KFZW / WOP, you can take a look at this in case something is happening to me. Thank you

Hi guys, I continued to research this time in my spare time, since nobody seems to have an answer for me, and I realized that my ECU does not have the KFTVSAKAT map for tuning, I tried to look for them in 2D without success, but I found another map that I think which can be a new fuel cut threshold, the map I refer to is called NWECVTM and it is a 5x1 map that only has one axis for temperature as in KFNWEGM and in internal sun they are also standard RPM tared at 1300 rpm at 80º Could this be the problem that my car does not do this system? Make a modification in that map to try to modify the fuel cut system, since using data obtained with vagcom, if I realize that it is delaying ignition as I demand in KFZWMN in the deceleration phase, but without obtaining the time of injection needed for the engine to explode

Tomorrow I will write the result here if someone has the same problem,

this is the settings that I am going to try to use

Dont use KFNWEGM, you'll have no control and it will overrun forever.
unless that is what you want?

And why did you change NWECVTM?
does your car have a CVT transmission?

All you basically need is:

CWSAWE
KFTVSA
TVSAG0 (if you want overrun when no gear is selected)
KFZWOP/2
KFZWMS

thanks friend! configure stock the rest of the maps and I will only try modifying as you say, but, I am not able to find the one you call TVSAG0 in my definition, could you give me a hand?

Take a look @ 0x15EB2

Hello guys im trying to find KFZWMN AND CWSAWE on this xdf!!

You found KFZWOP in this ecu!? Do you have an address in your MED17.5.25 mappack?

where is your flash file or ori?

Hey,

i tryed to make Pops and Bangs over AC with the help of this thread. Now i flashed it into my car and it works nice. But nothing over 3k rpm 4th gear.
Can someone check my file?

Why are you looking for KFNWEGM?

Hi bro, im trying to do it in a simos 10. i have a2l file, just need key maps to get it.
Im trying like simos18 but its way diferent. can you help a bit?

Hello

can anyone tell me if its possible that there are 2 'KFZWMN' maps in my bin? (6K0906032AA cupra 1.8t)

On overrun i edited KFZWMN in the lower load parts to -18, now with a simple log it seems the car is following this value when in this area
Although when i press the clutch (With KFTVSA sets to 2.00 seconds) the timing follows another map till 2.00 seconds are over then it drops just back to -18.

this way i don't get the desired ignition angle for pops as just when its getting fuel the ignition goes positive

Now it looks like, if i log the ignition angles,  "that other map" is named in my definitions as "KFZWMN HelperD"

I dont know exactly if the "KFZWMN HelperD" is actually an KFZWMN map and if i'am right that this map is controlling ignition angle on overrun with fuel


Anyone who can point me in the direction?
maps attached

The FR i have describes three different KFZWMN maps:

KFZWMN RL NMOT KF Min-Z ¨undwinkel
KFZWMNKH RL NMOT KF Min-Z¨undwinkel Katheizen
KFZWMNST RL NMOT KF Min-Z¨undwinkel f ¨ur Start und Nachstart

Ah there we are.

KFZWMN as i described will probably be KFZWMNKH
The KFZWMN is probably the KFZWMN HelperD one.

Thanks nyet!

Although i read about it I never thought about this.
Will try soon!

Edit: works perfectly with edited KFZWMNKH! Another problem was that KFZWOP values which i edited to x-20 where not low enough to make zwopt lower as zwspae

......but as always there are new challenges  :D

The goal was to make it pop/gargle between gear changes
This is working fine for now except for one thing,

When I go off throttle it took about 1 second before the timing gets negative and there are pops.

As far as I see its caused by the load. The load drops too slowly in my opninion and not only in the negative timing area.

Although when I disconnect MAF sensor this problem is over and load drops faster with earlier negative timings as result.

Now I don't know exactly where I have to search the problem,
The MAF sensor itself or maybe some maps I edited?

The maps I edited are,

KFZWMN/KH
KFZWOP/2
KFTVSA
KFTVSAKAT
KFZWMS

When I have the opportunity I will attach pictures of the maps.

While writing this post I doubt if KFZWOP may be the issue because this also used for torque calc??

Anyone suggestions?

It is probably easier to just write some code or have someone write some code that forces timing to a specified value and keep the injectors on with a different table instead. I hook Wped, use a Cat Heating table to keep the injectors on above a threshold and then force the timing to a negative value that works best on the platform im working on. That would be the best way to do it for you too i would think.

Looking at your last screenshot you've got 9.75 column as -18 and 18.75 column as near factory, if I let off and monitor load mine is around 16.5 on deacceleration, it would make sense to change your axis to accomodate for this as you're probably no where near the desired -18 degrees.

btw non turbo 1.8 already does this, based on kfzwmn. Dont know which "switch"/track it takes on min angle but its there, prolly you can follow it thru fr, i havent.

At the moment I don't have any experience with writing custom code. I am just new in this and trying to learn from it. For now I will keep up with this cause there is enough for me to learn and experiment at this time. but in the future I definitely want to do some custom code. Actually doing it with Wped would give me this fast reacting opportunity.

But like Blazius says KFZWMN is active now when on overrun so controlling ignition is no problem now. only don't know which fuel map it is following on overrun?






Edit: I realised myself that I have an atmosfered vented blowoff on my car. Just shame myself I dont realized this earlier instead trying to solve my problems.
When I go off throttle I lose air to atmosphere and I get a rich mixture what is resulting in no pops till blowoff closes and mixture gets leaner

Hi,

in KWZWMN maps do not use "offset" - 20, but "fill with value" - 20 option... ofcourse if using tunerpro

That is the location I have found in my findings for CWSAWE. Does anyone have KFTVSA for this bin.

Attached is the bin I am referring to.

Hi all,

I have a question - probably I forget about one parameter - what do i need to change to have pop&bangs when te car is not moving?
I change all of the standard values:
CWSAWE : 1
KFZWMN: -24 in the area (rpm/load) needed
KFZWOP1/2: first row -20 from original value
KFZW/KFZW2: match KFZWOP in changed areas
KFTVSA: duration 2,5 in area i needed

I noticed that pops are working over 30km/h, under this speed there is nothing :/

What should i look for to make my car gargles when it is staying?

Thanks in advance for help

Hello mate. The Value you are looking for is TVSAG0. In the M-Box file its located at 0x1571C with factor 0.01.
The unit is seconds and its for how long fuel cut is deactivated when your in neutral.

hope that helps !

Hey guys. First post here. I m tryimg to add some crackle and pop to my newly acquired Audi TT 225 AMU 8n0906018K.
I can nit find these addresses if some one can please help.
KFTVSA KFNWEGM CWSAWE
Thanks in advance.

CWSAWE 0x15722
KFTVSA   0X197D6
KFNWEGM  0X197AE

Legend! Thank you kind sir.

Hi nice to read this thread can somebody explain how to make pop and bangs on old ME7.1 what maps touch...

Same way

Hello together.

Im having trouble finding CWSAWE.
I think it is at 0x1C5A54, could someone confirm that oder tell me where it is?

I've attached my original file.
It is a 1K0907115Q MED9.1 from a Golf 5 2.0 GTI

Thanks in advance!

Hello Friends!

I have a strange problem with a S4.
Its a Stage 3 with k04 Turbos and stuff like that. It has a G-Box which I converted to M-File.
But no matter what I try it does not pop or bang.
I changed all maps that are neccessary but there is nothing.
KFZWMN
KFTVSAG
KFNWEGM
CWSAWE

In addition i tried to flash a file from another S4 (also M-Box) that pops quite nice. But also with that file the car makes nothing!
From logs I see that the Ignition angle goes to -24° and also Injection time is still greater than 1ms so there must be fuel but maybe no spark.. But why?? Is it because of the G-Box ECU? The other S4 has a D-Box ECU but i tried the exact same file on them. I think they are hardwarewise the same or not?

File is attached if someone wants to take a look.

I have the same problem with my D-Box. It only pops if i change KFZW into negative values, but that's not what we want.

thats nasty!
what forces the logic to use the latest possible ignition angle?

I cant point it out in the Funktionsrahmen.

Read the thread

KFTVSA - Overrun time in seconds (max 2.55)
KFZWMN - start with perhaps -20
KFZWOP/2 start with values like 20
TVSAG0 - 2.5s

Mess around with KFZWMN and KFZWOP untill you are happy with the result.

For stand still pops TVSAG0 is needed. Don't touch KFNWEGM you'll never have fuel cut.

It's all already in this thread ...

these are not no need to touch

we know that,

When you check my file you will see that I changed all these values, but there are still no sounds. On other car the exact same file works with pops, but on one particular car not.

Hmm if you have such possibility, please log pedal position on overrun in both your and your friends s4s.

Make a huge difference though

Can KFTVSA map be all 0.5 stock ?
i think i found it at 19627, could someone confirm this?

"$ 195FF"; "Restart speed map"; "KFNWEGM"; "8x5"
"$ 19627"; "Delay time for overrun shutdown"; "KFTVSA"; "8x5"
"$ 1578A"; "Code word thrust shutdown - reinstall"; "CWSAWE"; "1x1"
"$ 137CA"; "Min ignition angle"; "KFZWMN"; "12x16"
"$ 1389E"; "Min ignition angle cat heating"; "KFZWMNKH"; "12x6"
"$ 15A9B"; "optimal ignition angle"; "KFZWOP"; "11x16"
"$ 15B4B"; "optimal ignition angle variant 2"; "KFZWOP2"; "11x16"

Thank you so much, it threw me off when i saw 0.5 in KFTVSA so i was not sure if its correct.

Hi friends, a simple question about your experience. Pops and bangs are an effect of unburned fuel and timing retard in a hot exhaust. But my consult is how is your experience  in terms of RPM and ignition timing retard for pops or bangs? Of course every engine / platform / millage is different.

Hi,

I have a custom code for Pops&bangs. The code is writing 2 variables: zwout and nwe. Are these variables enough? As I read the topic KFNWEGM should not be modified. KFNWEGM->nwe with some offset so the code should change other variable for Pops&bangs?

Thank you

MED9.1

Data log lift off load, mine was 18.X I believe, so second lowest load line I set to 19 and put -20 in the required area (4500-7000 RPM)

Don't change KFTVSA or the car will drive itself due to not shutting off injectors.

You'll still get for example when you let off the throttle, 0.83 lambda, 1.00 lambda (pops) then 1.99 lambda when they shut off, so a few seconds at 1.00 with lift off pops and no driveability issues.

-18 was gargles, -25 was pops, -35 was abnoxious bangs.
