Overboosting, not following Desired Boost
Hi Nefmoto,
I've changed LAMFA, LDRXN as shown in attachments.
Running a full throttle run in 2nd gear, giving 100% pedal at once.
It looks like it's having a huge boost peak, and then tempers down below desired.
During the pull you can feel a * hik * which was not at the default map.
Hope someone can help me out.

2nd gear is dynamic. Use 3rd. Also post CSV.

Too much IMX.
You didn't log any of the PID variables, that would help.

BoostPID-I-Result","BoostPID-P-Result","BoostPID-D-Result
Those above are not the PID's you need?

Less KFLDIMX, and likely less Q2
Also, instead of an increasing KFLDIMX, i'd consider a flat KFLDIMX and tweaking KFLDRL to compensate
Finally, you're maxed out on your turbos up top, id reduce redline boost request. You're out of injector anyway.

You brought it down too low, and you didn't compensate via KFLDLR
Also, log pedal position and throttle plate angle or you won't be able to use ecuxplot properly.
