You schould pay someone to tune your car. Or learn a lot lot more.  You can't  run if you can't walk

0% WGDC and 17 psi of boost?  Sorry man but look at these things. Those are basic

If the bigger problem for You is 1bar at 0% then I am very well aware of that and i have told it here multiple times. Turbo came with 14PSI actuator. Thats why i want to dial fuel first and thats why i wasnt eager to do WOT right now. I myself would like to change it to 0.5bar spring ( it should be sufficent ?) I set WG to flat 0%.
I am not an idiot, im not flooring it like You think i am probably. Anyway, back to main question, is it fixable in KFKHFM or FKKKVS.

Don't bother doing any more tuning until you get your boost set up properly.

One thing at at time.

Fix what is obviously broken FIRST. Do not try to fix multiple things at once. I don't know how many times i have to repeat this, lately its literally been just about every thread.

What could interfere with ignition cut ? Car has als and hardcut, it works, but after some driving and turning car on and off ignition cut does not work. Overnight it started working again. No codes.
I suspected faulty maf, but everything seems fine in logs and trims. Could it be temp dependant ?  ( oil , coolant ) ?

If youre used classic als script then it's only faulty clusch sensor could be the reason
But I've seen script with tmot checking once so..

Tested with engine temp of 88 celsius, everything was working. with 93 celsius it wasnt .
Will log tsrldyn tomorrow. I dont know if that is coincidence, but when the spark cut error comes, it seems LTFT also stop working.

Ok i think i figured it out. Lifted NMAXF and now it is working.
When i want my hardcut to be at 7000rpm I usually set nmax to 7100, but with these settings there is " empty hole " before cut comes in. Tried nmax 7050 and it is alot better. My question is, if it can me lowered even more, or i can deal with delay elsewhere? I am not sure if it is the right way, but it did  the effect.
