Hi together;

I am pretty sure you will be able to tell quite easily, but I am ABSOLUTELY new to this topic.

I recently purchased a cheap 1.8t TT with a broken turbo. As responsible as I am, I ordered a cheap chinese K04-001 to bolt on.
Stock  MAF, stock injectors and a 2.5" exhaust with 100 cell cat.

A friend of a friend of a friend had a cousin ( you know how this goes ) who has sent me software for it, and it absolutely ran like ****.

I don't know why, he was a nice guy and sent 5 different approaches before giving up. More boost, less boost, nothing of his approaches seems to work.
All files resulting in the car choking when adding more than 15% throttle, hickups and no boost.

Then I found a basic stage 1 file for my car.
Car runs better, has good power while running 0.7 bar max boost at approx. 180 mg/s.
Under partial load I am getting a bad stutter resulting in no drivability, plus my target was 1.0 bar of boost as long as my injectors and MAF will take it.

THE PROBLEM IS, that the actual boost comes in later (cheap bigger turbo =/ slow spool ), but then exceeds the target boost by 150 - 200mbar at all times.

I want to avoid rpms over 6750 (due to high milage) plus I'd like to have LC and a hard limiter.

My question is, where would you start to get boost under control? What could cause the break ups under part load?
The other features can wait until my understanding is good enough for this ECU

Attached you can find all files I have recently flashed, while the original file and the stage 1 without pops work best.
Also I tried VCDS logging for the first time, with one pull at the end.

Hope my post does not violate any forum rules, tried my best 

SW: 1037352763
HW: 0261206439

Hi,
Thank you for the reply. I am sorry if thats the impression I have given you, but I actually read quite a lot.

But as I said, I am most certainly missing some basic understanding.

But I guess what youre saying is, that I should flash / patch my ECU to a certain HW and SW number, so I can find available sxf/ damos / mappacks?

Put a stock file on it, get ME7Logger working.  Different actuators need calibrated.  Fit OEM turbo and then calibrate or spend a while calibrating the PID, which you will struggle to do at this level.

This makes no sense. There are several well defined files you can cross flash. Stop wasting time finding maps.


Whatever PID experience you have, it shouldn't be telling you this. In particular, raising P would just exacerbate overshoot.

The main issues in the pid are WG linearization and integrator windup. P is almost entirely irrelevant; it has no bearing on controlling overshoot.

Finally stop using VCDS for anything other than scanning for codes and watching trims. Almost every single post and document advises you on what tool to make logs with instead.

This makes no sense. There are several well defined files you can cross flash. Stop wasting time finding maps.

Now I am starting to feel stupid.

From the ECU cross- compability list I can only run the original ECU for my APP TT 180.

I have found an XDF file for a 06A906032S ECU which actually seems very similar to my original file, has helped me to find quite a lot of maps, but still not the ones I need.

So - just for fun - I created a file for the 032S ECU. The things I have learned on here tell me there is no way this file works for my car, but how could you find out without flashing?

PS.: very thankful that you moved this to noob questions, and I thought after tuning some MS43s I would know SOMETHING  but I guess I need more time to learn

That is very good to know.

Since its the same engine code, I will look for the bootrom. If it matches, I will have my own software on it soon

First time making software for a turbo car, can't wait to see those pistons melting

You are right. I used that one to create that file.

I used marty's stage 1 as a reference, is that okay?

For the new file. Would you try crossflashing with those?
Sorry, I am just a little scared 

Did you get a file from Marty?
