Hi all, I have a friend with a 1.8t aum. ecu type me7.5 , the car was remapped some time ago, at the begining cars runs ok, (i mean ok because car started up and were very fast, but always smells a lot to fuel and waste a lot ).

Problems start some days ago, the cars start to run very badly, horrible idle, and imposible to drive, we discovered that if we disconect maf cas goes better, owner told me that he had installed some electric stuffs on car and maybe could damaged the ecu with a shortcircuit, he wanted to buy a new ecu, but i wanted to try the original file first.

After charging the original file car goes great, we can already connect maf, no fuel smell but just 150hp :lol: , we charging again the mod file and problems come back.

Is it possible to damaged ecu file with some shortcircuit? ANd maybe I read a corrupted file? i have no idea about fuel cars, so i can´t check the mod file, so i have no idead if problem is for a bad remap or a corrupted file or others.

Here are the mod file:

(file has nls and launch control)

could someone take a look to the file and to give some light on that?

thanks a lot

Who did this file?  It's terrible.

In theory a "profesional" chiptuner from my region....
 
some time ago engine blow off (head of the engine broken), we talk with the chiptuner and we told us problem was for a bad spark plug...

Any way, i´m going to try to made a decent file for that car by my own, becouse now i don´t trust  on chiptuners from my region.

No fuel, rediculous IRL/IOP, even worse RXN.  Launch/AL will be stolen from here too.  Start from scratch.

Sorry i don´t understand what do you mean with launch stolen, car had launch and nls, but it doesn´t work very good, if you did  nls car jerks a lot.

Yes i´m going to start with original file, identify all. thaks a lot!

WTF? I have seen bad files with "professional chiptuners" from Spain (I´m from here too) but this file makes me laugh.. amazing..

i'd actually rather get me one of those fancy ebay tunes than this, this is amazingly bad.
the person who did this obviously had no idea what he was doing, everything is just turned to 11.5  :o
delete this file with fire and never think of it again.
its incredible that the engine hasn't grenaded itself yet.

start from scratch.

Yes, the more incredible is, that guy has been  working  us chiptuner for 15 years, and lot of people think he is one of the best from my region (north of Spain), I start to know about chiptuning this year, and all the files I have seen from him are horrible, until now i have just seen petrol files, but thanks to all of you i know now that are bad oon all kinf of engines...

The funniest thing is that he always says that he made only safe files when you ask for more power.

I´m identify all maps and i´´m studing hard the wiki of this forum when I start to tuning it i will upload it here.

 thanks a lot for your replays!

The engine on summer broken, one spark broke and 2 valves damaged, Tuner told us that problem where for using cheap sparks....

He's straight up lying to your face, he knows that his tune is a dumpster fire(or maybe he doesn't?)
I'm no expert tuner, but even I can see that the tune he made is ridiculous
Anyhow, I hope you didn't pay a lot for that "tune"?

I don´t know how much my friend paid, but more than 200 euros for sure, until now I only tunned dieselcars, all my group of friend have my maps on their diesel cars, but for fuel cars we pay that guy. But this is the last time.

As i said i´m working on a new file for this car, with the help of this forum is difficult not to do it a bit better than  that file. 

I have already tunned my new LDRXN with more real load values.  ;D

I'm a little confused about what you mean about fuel(gasoline?) and petrol(diesel?)?
I'm pretty sure you mean diesel and gasoline, but not sure which is which? :)

What xdf are you using? The one I'm using for HJ, doesn't seem to be showing correct values.

How so?  The "correct values" are so far out it's probably throwing you.

Language problems i´m afraid, yes i mean diesel and gasoline hehe

hi i´m using this mappack for  winols, i got it from other forum:

hi all, i let you here some of my progress, please feel free to give your honest opinion:

My LDRXN:

I let LDRXNZK exactly like LDRXN i don´t know if this is correct, it  was 370 of load along all the map with previous remap, i think thats the reason why we saw on vagcom a dtc about air leaks between dv and manifold.

KFFDLBTS:

KFLBTS:
 with factor for lambda values
(http://i63.tinypic.com/anc4jp.png)

with factor for AFR values (this way is easier for me)

(http://i65.tinypic.com/211qfl0.png)

What is the hardware setup of the car?

Sorry, the car is a 1.8t AUM (k03s) with big fmic,3"  downpipe  and 2,5" full  exhaust,  3,5 bar fpr, rs4 sparks, and now tfsi coils (on picture are stock ones), conic filter silicone inlet pipe, forge 008 dv  and a lot of things anulated like second  air pump, evap catalist etc...

Here i let you a few pictures of the baby, it`s a mk2 swap to  1.8t:

(http://i65.tinypic.com/34qqmv9.jpg)

(http://i68.tinypic.com/mw47lk.jpg)

(http://i68.tinypic.com/312xpio.jpg) the car is  full made by us in our modest garage except software until now.

That looks like a pretty nice setup.
But that setup looks like k04(210/225HP) and not a k03s :)
And I noticed that you have a 3.5 bar FPR, is the appropriate maps scaled for that?

that's a k03.

BAM hot side for sure.  How do you know it's a K03?

Piping, inlet, TIP and turbo position looks like K04 :)

Becacuse I made part of the swap  ;D it is k03s but we had to use manifold from a bam and turbo pipe to be able to use
 big fmic with  not too long pipes.

actually i have no idea if the maps are scaled appropriate for that

KRKTE needs to be scaled :)
What about injectors and MAF?

Stock injetors and maf

If it's a K03s your revised LDRXN would be better if reversed.
Meaning that the little turbo is out of breath in the high RPMs, but spools fast in the low RPMs.
So your highest load% should be low to mid RPM tapering down towards redline :)
Don't get me wrong, the turbo could probably push the load, but it won't be happy doing it.
How big is the FMIC?


Okay, then KRKTE "should be enough"  :P

the fmic was as big as possible, almost all the front of the car, you can see the pipes going to the intercooler in the picture.

About LDRXN  i made it that way becouse before engine died soon no power passing 4500  and  too much on low rpm, it was very dificult to drive it.

K03s isn't really a high performance turbo.
Its an small eco turbo with a little extra, and it gets really hot if pushed hard  :-\

and the FMIC sounds oversized for the turbo, but i bet high IATs post IC is'nt a problem :P

Anybody is free to correct me if I'm misinforming him? :P

The problem is IRL/IOP too.

i´m working on the original file, i don´t modify those maps yet.

The car hadn´t got lag, the fmic is big but pipes are short  ;D

ON the other hand how do you see the other maps?

Yeah, I scratched my head at that too.
Stock IRL/IOP should be enough for a K03s, maybe up the last row a little considering his setup? :)

Hello i let you here my ols, I started from the scracht as you adviced me  with a original file, please could you give your opinion, it is already not finished, no ignition maps touched yet .

I don´t know if i tuned properly LDRXN (i tried to made it soft) KFMIRL and KFMIOP, an on other hand i dind´t know if is necesary to touch : LAMFA, (KFLDRL) and (KFLDIMX)

I let KFLBTS with an afr of 12.5 more or less on high loads and rpm, and i´m afraid my IRL/IOP don´t be alrady  ok .

Thanks to all!

Can't really tell without logs :)

[KF]DLBTS and KFFDLBTS - lambts = KFLBTS + [KF]DLBTS*KFFDLBTS. Therefore, setting KFLBTS to 1 where you don't need it won't disable bts, you also have to set KFFDLBTS = 0 as well.[21] Note that Mbox has DLBTS (2D), not KFDLBTS (3D).[22]

What about TABS?  Fuel how you want to; either with BTS or LAMFA.  Needs logs.

I don't see any logs?


Read S4wiki, use nef search function for any questions

Return to file stock, log car.
Adjust file methodically in steps, log car again
Analyse log.
Adjust again

Rinse and repeat

That way people won't need to copy and paste stuff into this thread for you to learn.

sorry, i forgot to attach the winols files, im modifing the original file  reading a lot the s4wiki and forum, I know it is not finish but i would like to know  if i´m going into the correct way.

Did you read the part about logging?

Because you still haven't provided a log

here are some logs

(http://www.lignumgroup.com/yahoo_site_admin/assets/images/Logs2.15113336_std.jpg)

now, what's wrong with his tune?

OK, i will made some logs and post them here, problem is until weekend i will not be with the car.

Well, forget it then. We wanted them now.

Just kidding.

hehe i guess, i hope to do them tomorrow till them i keep working on file.

Car definitely is not going good, it has a horrible low idle and maf is reading 227mg/s on idle!! we changed the maf for a new some weeks ago even we revised all the wiring but nothing extange, could someone know the reason of that strange reading of the maf?

Please follow instructions and the stickies which tell you to POST THE CSV not a freaking screenshot.

Nobody can plot a screenshot.

http://nefariousmotorsports.com/forum/index.php?topic=4094.msg41336#msg41336

And please use ME7logger, the resolution of vcds blocks logging is awful.

But just from the screenshot I can tell that something is very wrong.
Your MAF flow stays at 227.25 and 229 g/s in all logs.
You're only requesting 0.58 bar tapering to 0.35 bar?
And the fuel is way to rich for those boost/engine load levels.
It also seems like you have a problem staying on target AFR, you're either way too rich or way too lean.
But I suspect that it is your 3.5 bar FPR causing that problem.

Sorry i will post csvl and download me7logger, for the log  que used stock fpr becouse car was very very rich, i think problem is on maf for the so high lecture,  high maf --->low lambda.

On the other hand cae right now is with stock file, so 0.5 is max turbo i think for a aum.

Is maf stock? If not, then is tune scaled correct for the maf fitted?

either your MAF isn't stock or it's broken.

You need to fix that MAF issue before you do any form of WOT pulls.

we have test a new maf (original one from a car running good) so for sure problem is on the wiring (ecu is even new) wiring wil be cheked this week while that I will keep working on the file.

Thanks to all!

Hi all, we are already  working on the maf problem tomorrow we will wiring again the maf to the ecu i hope solve it!

Here you have my progress on the ecu file, i´m sure i will have a lot of mistakes but i´m trying to give my best, reading and reding a lot the forum:
