Attached you will find my 1st and 5th log from today. Environment was like 17degree celsius. I parket the car to let it heat soak to reproduce the problem. As you can see, first log was wonderful, 95% 1,6bar like requested. Last log was 85% highest and underboosting. Unfortunatelly i am unable to interpret the newly logged vars. I will have to read alot about this. edit: https://s4wiki.com/wiki/Tuning#I-Regulation_adaptation |

For some reason you have a whole lot of imx trim activity... not sure why they're so crazy negative, unless there are times when you are crazy overboosting

This doesn't make much sense
Why are the imx trims going DOWN during underboost?

Maybe its because i am near sensor limit? At least Ecu is thinking this although im running big sensor and 5120hack? So it is not related to heat developing from first to fifth log or something, its more like a long term trim and connected to point in time after last flash? I reflashed the ecu yesterday before first log.  |

If I had to guess, there is a sign error somewhere.

my LDEIAO, LDEIAP, LDEIAPS and LDEIAU is chanced a bit from stock could be related to 5120hack, i have to check my old revisions when i changed this and why LDEIAO from 40 to 20 LDEIAP from -20 to 1270 LDEIAPS from 50 to 20 LDEIAU from -60 to 1270 LDIATA and STLDIA is stock. What do you want me to log? I have nothing like STDIA in my logger config(s) thx Not sure if this will help you at all, but I took a look at a 5120 file I've done for a sanity check. Each of the params above I divided by 2. LDEIOU 40 -> 20 LDEIAP -40 -> -20 LDEIAPS 60 -> 30 LDEIAU -40 -> -20 Though I'm not running the pre control method. |

Definitely not a noob topic  Moving to main tuning forum, as this could be helpful for others |

Solved, thank you gentlemen
I am not sure which of the 3 maps was the problem, i didnt test them individually.
All of the imx trims are within a small range now.
attached first and fifth log
