Hi,

On WOT i am hitting what feels like a limiter in over third gear, i am thinking it is either load related or MAF limit. Only requesting 1.3 bar boost. See attached logs (full log 2nd and 3rd gear & 3rd gear extracted) and snapshots of my KFMIRL and KFMIOP

Any help Appreciated

May or may not be solving the issue here but had another look at KFMIOP (see attached), showing it peaking at 94% at 4520 then reducing. Should i change this to rise all the way out to 7500?

Thanks

Same. No PID variables though so who knows what is going on there.

Ok, so is that causing the ‘limit’ or is it torque intervention?

I did calibrate kfldrl due to tighter wastegates with 0% to 80% runs and a have increased kfldimx

You didn't log any of the load limits either, so no way of knowing.

1. This should be in noob section.
2. In the log the car revs exactly as far as you have the pedal down.

You know, maybe try not shitting pants and lifting off the pedal? Cheesy

Also proper logs are taken in a single gear as a single pull. No idea wtf you are trying to do.

Still no sign of the relevant load limits in your log

Thank you for the kind words. to note gangi is not correct! TDI box matched to 2.7t so no i am not lifting off. Changing into a higher gear when i am hitting a "limit" because it wont rev past this point.

Are there any specific parameters i should log and i will do one single pull in 3rd.

EDIT

Found the variables i should log from wiki

QUOTE FROM WIKI
To help diagnose, log these:

rlsol "EngineLoadRequested" Logged
rlmax_w "EngineLoadCorrected" (this is a misomer, it should be something like "LoadLimitCorrected")Logged
rlmx_w "EngineLoadSpecified" (this is a misnomer, it should be "LoadLimitSpecified")Logged
ldrlms "ChargeLimitEngineProtection"
ldrlts "ChargeLimitTurboProtection"


I will log again with the two missing variables
