Title: M3.8 boost threshold Post by: kacperoooni on July 06, 2020, 12:17:53 PM Hi,
Could somebody tell me name of maps to disable/raise overboost thereshold in M3.8? I tried GDKLDOB, ELDOB and GNLDOB without any result..

Still getting fuel cut after ~0.2 ms deviation between requested and actual load

If you are hitting 12.75 then that will be the problem. Why do you have deviation? In all the times I've tuned these with various turbo setups I never had this problem.

I needed to touch KFLDTV because without it I have boost oscillations. After getting it tuned the car seems to drive okay until the conditions outside change... Then again boost oscilations and overboost in result, fuel cut etc. The logging frequency is really low so I can't tune it like with me7 logger. The code I am getting with fuel cut is 00544 - Maximum boost pressure exceededIf you are hitting 12.75 then that will be the problem. Why do you have deviation?
