You are not interestend in good log  Cheesy

Why is there a bump in rpm
why are you starting above 3000rpm
why dont you push the pedal all the way in

The line of your maf readings is strange and your fueling is rich.
Would reduce timing and fix fuel and boost first.

What turbo is this in detail?

i test car on motorway,  and are other peple, im insert on 3 gear and log for this rpm. my problem is the turbo managment, the turbo pressure with n75 dont match on what i have on maps. if i pute the full pedatl on 4 maps , with 3bar of pressure i damage engine. i like picco 1.5 and 1.3 costant. i cant do that. my turbo is franken turbo f23 kit, il hybrid k04 turbo , maybe from tfsi ,im not sure.

You havent done this file on your own, have you?

There are lots of small useless changes.

Injectors: only krkte, no tvub, temin and so on
Maf: which r32 in detail? whole maf or only sensor?
There is kfldrapp changed but CWMDAPP is not?!

Would start from original file and recommend to log on the night time when motorway is empty.

dude.  doood......

You need to just back up and start over.  You are in over your head at this point.   You obviously have not attempted to learn the basics.  I don't have anything constructive to add here, other than the fact that ultra-noobs seem to have a better handle on remapping than you do.

ffs.....

I really hope it's your own car you're doing this to.

You need to read A LOT more, before attempting what you are doing.
Read all you can find about PID controllers and calibration of them.
And then read all about LDRPID module.
That would make you able to calibrate a different turbo to the ECU.

And please read until you understand the fundamentals of fuelling on this ECU.

Personally, use the PID linerisation method and just leave it without a PID.  Simpler to get your head around and will stop this 3 bar shit.

Let me get this right, you have the N75 feed line hooked up at throttle/intake manifold?
And you have a check valve in that line, oriented so that it only sees boost not vacuum?

That would prevent boost from escaping the manifold->N75->wastegate loop
keeping the wastegate open unless the N75 is venting. In theory.

Anyway, glad to hear you got it sorted Smiley
