Afternoon,


Please don't shoot me, just after simple yes/no answers.

Car is currently stock bar a 008 forge.

In my mind there is no point starting a tune from the stock 150hp map when we already know the same kit does 180hp.

From what I understand the other two .bin attached are 180hp and a genereric stage 1 tune? can I flash them, log and tune from there?

I only have vcds lite so I cant pull the fuel trim info, is there another way to get it?

Please be nice, any info/ help much appreciated.

It makes no difference because the ultimate increase from 150/180 to Stage 1 will be 190/200.  You won't get more from the 180.

I get that I will get to the same point/ power in the end but surely starting with the 180map is a quicker/ better place to start from.

Will either/ not of the attached bin files achieve what I am asking?

those three files all have the same boost  profile .

in fact , there is no difference between the three of them , they are all the same file .

wrong xdf , ignore

wrong file posted

hopefully this should be the right file or my tunerpro is screwed up !! ,

Hi Manford,
What adam is saying is exactly as it is. There is nothing to be gained from using either or file.
I'm very new to this subject, and I have an AUM myself which I have applied a bit more fuel and boost to. Only about another 3 psi across the board though.

But the principal is the same weather you start with a 150 or a 180 file. If you want 190/200 you still must edit the file for that regardless.

All the very best
O.T.

Is there another way of grabbing the fuel trim info? My lite version of vcds won’t do it

AFAIK, Short and long term fuel trim is part of generic OBDII info,
so any OBDII compliant scanner should be able to show it.

This is prob a stupid question but is there anyway of putting all the info in english? Cant say my German is theat fluid. ;D

the s4wiki is all english

Very true.

Those three files are all identical.

Do you know of any that are pc based and work with generic vag com cable?

VCDS has generic OBDII mode, but I'm not sure if VCDS lite supports it?

Don't bother with VCDS.
Do the S4wiki and grab ME7Logger. There both excellent...

All the best
O.T.

Agreed. But it All depends on what type of cable he has.
All depends on what Chinese "vcds lite" clone he has.

I have a blue ebay special cable, has worked fine so far, have managed to now download and upload a map.

I am slowly plodding through all the info and trying to fill in the gaps....slowly slowly, need to get some good logs to make any further tweaks.

The me7 wizard, how accurate/blindly should that be followed? I can't find FKKVS map section in the bin?

I have been told but I can't find the info, whats max recommended boost on a ko3s/aum? 13.4psi rings a bell.

Then you should be fine.

Me7wizard can help you get ballpark numbers,
but I wouldn't recommend following it blindly :)

For FKKVS trimming, i can recommend FKKVS fixer found here on this forum.

Are we talking clapped out boost or sane boost?

Well I would rather it didnt go pop, just whats a good figure to being aiming for/ stop at and know I'm not taking the piss?

When I search in Tunerpro for FKKVS it doesnt return a paramter in the search?

Is there a way of swapping the x and y axis over so I can copy from one to the other? at the moment im entering all the info manually.

1.1 bar in low to mid RPM and taper to 0.6 at redline, that should give a nice bump in torque and keep the IAT low.
It can do more, but your IAT will go through the roof if you're on stock charge cooler :)

That's because it's not defined.

Switch major order from row to column, and vice versa.
That will switch orientation of the data cells but not the axis.

ME7Wizard IMO is old and outdated.  I never got good results either.

I have stft and ltft of -0.4 and -1.6 which way do I adjust the figures in MLHFM? do I increase/decrease the whole table?

If my car detects knock and adjusts do I decrease the figures in KFZW by the amount of degrees I want to reduce it by? so if its taking 4degrees out, do I reduce a figure of 34 to 30?

Those trims are fine.  Leave it alone. :)

Yes.  Reduce value in corresponding RPM/load cell.

Well after two tweaks I know have two sections with -0.75 degrees of knock in, not the 5 degrees I did have so well on my way to sorting that issue, im assuming I can get to a point where I get no knock detected over a WOT run?

My other main issue, or issue that I know of is im getting a boost spike from around 2500rpm....

You're fine


Post logs, make sure you include wgdc and i max

I've got waste gate duty cycle, but I dont think I have I max...

Not my latest log attached, but it shows the boost spike better,

IMX is way too high at 2500rpm and up.

IMX?

How do I adjust/bring it down?

Go to the S4 wiki, hit ctrl F and put in IMX, then you're there. Its the I limit of the PID, dropping the limit will help with the overshoot

Ok, so little confused, LDIATA is pretty much the same in every box.

I cant find a KFLDIMX, LDRQ1ST, KFLDRQ2 or DSLOFS in my bin? Its highly likely im being daft, but I cant adjust parameters I cant find.

Will increasing KFLDHBN help my overboost issue?

I've just read on another thread LDIATA should be set to 0?

I have already set KFTARX all to 1.

None of that will help if your IMX is bad.

So far ive kinda followed/ understood whats going on and what adjustments change influence what, but this IMX bit is confusing me.

I can’t find most of the parameters listed to adjust?

Can you point me in the right direction, looking at the s4 wiki, I should have a flat KFLDIMX, I cant find this? or these paramters KFLDIMX, LDRQ1ST, KFLDRQ2 or DSLOFS ??

Have the above parameters been renamed in vw or aum bins?

go into your tunerpro and click on the parameter search tool , type in IMX , its their  :)

No, you should have the proper KFLDIMX for your car.

Ok, changing the xdf file I was using has given me access to a whole lot more parameters....so I can now see KFLDIMX, which is a good start.

My boost seems to follow requested and actual for most of the pull just between 2.5 - 3 I want to bring the spike closer to requested, how biga change should I make to noticeable changes? Should I bring all the highlighted cells down by 1,10? and bringing the figures down will help with boost overshoot, increasing the figures will help with a lower actual against requested?

I have managed to get my AFR to follow a smoother ramp, but I think I need to check my timing.

FKKVS - what is the x axis in relation to goes from 0.9 to 19?

The wiki says FKKVS is flat in stock, mine is all over the place?

Injector pulse width in ms.

Depends on what car the file is from.

Remember that s4wiki is made for ME7.1 and S4.
But since and ME7.5 is pretty much the same, most of it can be carried over to 1.8T :)

Hhhhmmmm ok, without sounding stupid so how do I adjust the table to compensate/adjust rich or lean areas.

Reduce the figures, to increase fuel in given rpm row, but how do I know which column to increase? or do i increase the whole row?

You tell us. What do different cells in a column represent?

I clearly dont know hence the question,

"Reduce the figures, to increase fuel in given rpm row, but how do I know which column to increase? or do i increase the whole row?" was me asking for a sanity check/ as I understood, if wrong please inform/guide.

I can follow that I have rpm onside, and injector pulse width in ms but I don't understand the relationship.

How can you not know what each axis of that map is?

Ive gone back to my overboost issue....


I dropped some of the figure in KFLDIMX by 5 and it made no deifference, I dropped them by antoher 5 and my overboost dropped significantly, I dropped the figures a little more and its not brought the requested and actual any closer.

I have now added LDIMXA 0-4 to my logs, my latest tweak reduced Irange 2 but not Irange4.....

Am I missing something? Or what do I need to check?

log I-max

looks like it is still too high between 2500 and 2750

Reduce KFLDIMX more between those ranges, do I need to do it at all pressures or just the higher end 800-1000

You tell me. What is that axis?

Pressure, in mbar.

My log states baro pressure pretty much sits at 1000m bar, so I would only need to adjust the top column?

I know Irange 1-5 are all related to the the PID, but does each one relate to a certain relationship/factor? Range 4&5 are almost totally straight, but I assume they should be at 0?

Does my current AFR look ok or would you adjust if further?

No, it is not baro pressure. What does the wiki say the axis for IMX is?


What irange are you talking about? STLDIA?


It is probably fine for your boost levels. What made you choose that value?

x axis is a relative requested pressure

1100 hpa just shy of 16 psi, which is higher than i'm requesting so I don't need to change my axis scaling either.

Yes logging ldimxa_0-4 to give me the STLDIA 1 - 4 info.

My afr at the top end was dropping to nearer 11 than 11.8 so I made some tweaks and brought it back up, it needs to drop to 11.8 @ peak boost so around 3k? where as mine doesn't drop until 4250. I brought my initial down from 14.75 to 13. Info seems a little contradictory on AFR, some say it should ramp down, some 11.8 across the board?

STLDIA is really not tuned that way. It simply marks out rpm regions that are likely to need different imx adaptations.


11.8 is fine everywhere. To make any changes that make sense you'll need a dyno to test.

Cool I will keep adjusting my AFR to aim for 11.8 across the board.

How do I know what relates to STLDIA 1 to make changes to improve that or 2,3,4? Or is it a case of as I keep tweaking KFLDIMX those figures will all head towards 0 and when they are all solidly at 0 I know im ok?

I keep finding I have no knock on several pulls, and then one will have -0.75 somewhere in the run, if I remove another degree of timing in those areas that will bring me more into a happy window?

No. that isn't at all what those are for. I tried to explain it but it doesn't look like you understand what I said :/

If everything was perfect you would not need IMX adaptation or STLDIA at all. The purpose is to supply a way to have separate trims for different operating regions, kind of like fueling has separate idle and part throttle trims.


No, thats fine. Without a dyno, that is the only way you know you are getting all the timing your setup can tolerate.

Sooooo.........My imx is currently ok and dont worry?

If the car removes 0.75 from time to time, surely I can remove more timing until it adds some and then find a happy medium?

Looking at my latest two logs can you see/recommend anything I need to be aware of or tweak further? My AFR i already plan to bring to a more level 11.8.

It can't add timing. It removes timing when it senses a knock event.
And steps it back to set value after a specified time window with no knock.

0.75 °KW knock retard is fine. What octane are you running?

Then you're fine.
Might even be a little headroom, and that's okay.

Cool, thanks

Anything else in the logs to look into or all look ok?

Damn that looks good.

Well done.

Really? I’m not sure if you are serious or taking the piss?

There must be something that could be improved?


What’s currently my limiting factor? I know the common upgrade route, tip, injectors, fmic.....

No, seriously, good job!

I can't find anything obviously amiss.

You do have a bit of injector left. You might consider a bit less boost taper if you are feeling frisky :)

The next limiting factor is turbo.

I am missing about 2500 rpm of log, why dont you rev it out untill at least 6000? Not so interesting for boost control, but usefull for fueling and temperatures!

Oops. Good catch. Did not notice that.

Thanks. I’m pleased with the way it’s gone.


I do have some logs that go to about 5.5k, the road I use to log on en route to work I run out of room, 3rd gear redline your shifting.

The current weather isn’t helping my logging....

Another thought.....all the tweaking is done in the high load areas of tables, WOT,  is it worth making tweaks throughout the tables as this is where you spend 90% of your driving?

By and large the stock code is pretty flexible, aside from part throttle issues if you have wastegate that is stiffer than stock.

****Bit of an update*****

Car went for MOT today and failed misearbly on the emissions. Test is carried @2500rpm with no load, and I am running very rich.

Is that because the first column of LAMFA AFR has been incresed to 12.52 from 14.70?

KFTARX was adjusted slightly but in higher load/rpm sections.

KFMIOP and IRL wont affect the emissions.

why would you run anything but 14.70 at idle/low load?

Either run 14.7 everywhere on LAMFA for ticket (and have a cat), or find a better tester...

I'm a bit baffled, because he should be running closed loop everywhere but WOT

@manford post the bin and I'll take a look mate

He's probably using the 06A906032HJ file - There's a lot of fairly well defined map packs floating about that haven't quite got the lamfa defined properly. I think i saw a guy on facebook with similar issues. Probs the same dude.

Sounds like me, 1.8t tuning group?

Aye, it will be.

I mean *TRP* had his out by one byte and it's fucked part throttle.  As he pointed out though, it's an easy mistake to make.  He even made it himself.

How many times have I said to 16-bit align maps?

Yeah, it was effed.

Fixed now.

FUEL EVERYWHERE.

Aye I seen this one on the 1.8t tuning page aswell
