Title: Overrun Flames, Gargle, Pop
Post by: adam- on November 03, 2014, 02:04:19 PM
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?!


Title: Re: Overrun Flames, Gargle, Pop
Post by: contrast on November 03, 2014, 03:56:42 PM
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... (:

Title: Re: Overrun Flames, Gargle, Pop
Post by: adam- on November 04, 2014, 10:56:08 AM
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.


Title: Re: Overrun Flames, Gargle, Pop
Post by: contrast on November 04, 2014, 11:57:17 AM
-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.


Title: Re: Overrun Flames, Gargle, Pop
Post by: contrast on November 04, 2014, 11:59:36 AM
I should add that stock catbacks and downpipes dont give the desired effect as good as a louder catback and catless downpipes


Title: Re: Overrun Flames, Gargle, Pop
Post by: dayofthejackal on November 04, 2014, 12:05:52 PM
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.


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.


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.

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.

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'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

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


Title: Re: Overrun Flames, Gargle, Pop
Post by: mbkr89 on November 07, 2014, 03:25:46 AM
On my Med9.1 the max value in kftvsa is 2.55sec :(


Title: Re: Overrun Flames, Gargle, Pop
Post by: contrast on November 07, 2014, 04:35:44 AM
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

Post by: spacey3 on November 07, 2014, 12:20:37 PM
On my Med9.1 the max value in kftvsa is 2.55sec :(

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.


Title: Re: Overrun Flames, Gargle, Pop
Post by: mbkr89 on November 07, 2014, 12:46:17 PM
ok, so i will change it back to 2.5 sec. 

how much degree ignition at the last 2 rows ?


Title: Re: Overrun Flames, Gargle, Pop
Post by: contrast on November 07, 2014, 01:21:18 PM
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

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.


Title: Re: Overrun Flames, Gargle, Pop
Post by: mushtafa on November 08, 2014, 11:51:22 AM
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?


Title: Re: Overrun Flames, Gargle, Pop
Post by: contrast on November 08, 2014, 12:20:58 PM
I dont kniw either. Easiest way would be to log throttle angle or smth during overrun.


Title: Re: Overrun Flames, Gargle, Pop
Post by: contrast on November 08, 2014, 12:25:54 PM
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.

KFTVSAKAT set to 1 second between 1K- 2K and 3 seconds between 2K and 4K
KFZWMN set to -48 between 1K and 3.25K

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.


Title: Re:
Post by: mushtafa on November 09, 2014, 05:44:52 AM
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.

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

Title: Re: Overrun Flames, Gargle, Pop

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


Title: Re: Overrun Flames, Gargle, Pop
Post by: janne on November 26, 2014, 10:49:42 AM
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 =)

KFTVSA
KFTVSAKAT
KFZWMN

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.


Title: Re: Overrun Flames, Gargle, Pop
Post by: janne on December 03, 2014, 06:30:27 AM
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

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.


Title: Re: Overrun Flames, Gargle, Pop
Post by: cobblers on March 16, 2015, 02:31:14 PM
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)

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 !

Post by: !nfern0 on April 27, 2015, 12:56:30 PM
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...

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!

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?


Title: Re: Overrun Flames, Gargle, Pop
Post by: !nfern0 on May 09, 2015, 04:39:06 AM
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. :)

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.


Title: Re: Overrun Flames, Gargle, Pop
Post by: mushtafa on May 14, 2015, 01:14:14 PM
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...

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?

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. :)


Title: Re: Overrun Flames, Gargle, Pop
Post by: tjwasiak on May 16, 2015, 07:34:48 AM
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).


Title: Re: Overrun Flames, Gargle, Pop
Post by: !nfern0 on May 16, 2015, 08:38:06 AM
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.

Post by: vwaudiguy on May 16, 2015, 08:10:21 PM
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!


Title: Re: Overrun Flames, Gargle, Pop
Post by: !nfern0 on May 17, 2015, 05:08:15 AM
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).

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.

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.

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.

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.

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...

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.

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?

Post by: Audi100LS on September 10, 2015, 07:28:30 AM
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.

Post by: vwmaniac on February 12, 2016, 04:00:12 PM
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...


Title: Re: Overrun Flames, Gargle, Pop
Post by: contrast on February 13, 2016, 10:36:59 AM
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.

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. :)

Post by: Rl on April 07, 2016, 04:32:29 PM
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?


Title: Re: Overrun Flames, Gargle, Pop
Post by: Sonny on April 17, 2016, 12:14:18 AM
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!


Title: Re: Overrun Flames, Gargle, Pop
Post by: dream on May 16, 2016, 03:14:42 AM
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):

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

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.

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

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?

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.

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


Title: Re: Overrun Flames, Gargle, Pop
Post by: Dave9n3 on January 23, 2017, 02:54:50 PM

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?


Title: Re: Overrun Flames, Gargle, Pop
Post by: fukenbroken on January 23, 2017, 03:21:41 PM
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


Title: Re: Overrun Flames, Gargle, Pop
Post by: Dave9n3 on January 25, 2017, 11:28:37 AM
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.

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.


Title: Re: Overrun Flames, Gargle, Pop
Post by: TijnCU on January 26, 2017, 01:56:30 AM
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...


Title: Re: Overrun Flames, Gargle, Pop
Post by: Jim_Coupe on January 26, 2017, 02:09:06 AM
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?

Post by: 4ringpieces on January 26, 2017, 12:21:09 PM
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




Title: Re: Overrun Flames, Gargle, Pop
Post by: 4ringpieces on January 26, 2017, 03:17:11 PM
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.

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,

- 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

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?

Le problème est que, en roulant une charge faible, la voiture au régime du retard à l'avance la voiture fera un sac, je remarque que lorsque la pédale d'embrayage fonctionne, l'ecu active une autre carte. Parce que la détonation ne se produit pas et la vitesse Baisse plus rapidement, mais je ne peux pas trouver la carte à modifier pour que le délai ne se produise que lorsque la pédale d'embrayage et actionne.

Post by: nitromanstonV on April 22, 2017, 08:32:32 AM
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.

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..

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.

So just by flattening KFZWMN I can get gargles?
I've read every site of this thread now, it's a little bit confusing...   ;D

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.



Title: Re: Overrun Flames, Gargle, Pop
Post by: ReproLogic on October 17, 2017, 02:08:48 AM
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? :)

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?

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

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.

done only ms41 before in my e36 with overrun and other things

Title: Re: Overrun Flames, Gargle, Pop
Post by: Dave9n3 on January 19, 2018, 04:40:15 PM
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?

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

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?

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.

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.

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

Post by: ibizaCUPRA18t on June 15, 2018, 02:52:41 PM
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!

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.

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.

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.

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.

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.


Title: Re: Overrun Flames, Gargle, Pop
Post by: opctim on June 29, 2018, 02:49:38 AM
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?


Title: Re: Overrun Flames, Gargle, Pop
Post by: adam- on June 29, 2018, 02:54:58 AM
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)

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.

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...

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!



here is the answer:

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).

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!

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.



Title: Re: Overrun Flames, Gargle, Pop
Post by: KasperH on July 23, 2018, 04:29:26 AM
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.

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.

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.

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?

Post by: opctim on August 12, 2018, 11:26:34 AM
@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


Title: Re: Overrun Flames, Gargle, Pop

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.


Title: Re: Overrun Flames, Gargle, Pop

Title: Re: Overrun Flames, Gargle, Pop
Post by: MetalForLive on August 12, 2018, 11:24:20 PM
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.

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?


Title: Re: Overrun Flames, Gargle, Pop
Post by: MetalForLive on August 15, 2018, 04:27:52 AM
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.


Title: Re: Overrun Flames, Gargle, Pop
Post by: opctim on August 15, 2018, 05:47:57 AM
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)

This is actually what I‘m trying to achieve.

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.

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


Title: Re: Overrun Flames, Gargle, Pop
Post by: MetalForLive on August 16, 2018, 09:57:40 AM
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

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.

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?

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.

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.

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

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.

@Iain:

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

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  ???

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?

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

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?

Hello, thank you for your reply ?

Could you post some screens of what you did ?

Thanks.

Custom code.

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?
