Made changes according to you post and made logs. Same thing. worked once .

When it worked on CH file, it banged crazy like ak47 shooting. Right now, it only bounces and makes pops once. That made me thinking that it does not work.
Is my understaning wrong ? Should not be there always constant fuel ? As from logs i see fuel is also being cut off. That time when it worked, fuel was not cut off ( as i see from logs ).

Thank You, really appriciate Your help. I checked ur file, and for the sake of testing, i changed rpm axis and kfzw/op like you did. I have long time suspected that i have wrong temin, as i still do not fully understand how to calculate it nor what value is  right. For the sake of test i changed temin also. And BOOM. Hardcut has never worked so well. I still will test either was it effect of temin or ur settings.
My temin was 0.25, changed it to 0.3. As per calculation, which is found on this forum, it should be 0.45 . Injectors EV14 550cc 4bar

So i have decided to pursue the path to do 5120 hack. I have tested IDA for a week, so far no progress    I guess the hardest part is to do asm changes, when i have never touched IDApro. As we say, no harm asking, is there anybody here that is willing to help me out with asm changes ? Nevertheless, I will try to understand it myself.

Anyway, as i did not found any working files of 5120 for my ecu, i made my own. Took time, but it is working.  All was done per instructions on S4wiki.
And thank you for help @rogerius for finding missing maps and confirming my asm locations were right.
I will add  stock file with 5120 applied and full kp + 5120 . Did not post logs as i was not happy with my boost. Need to figure that out that
