Hi,
Then i step down the pedal fast (WOT) at low rpm (around 1800rpm - 2500 rpm) The engine just cuts the power for som milliseconds and after that it gets back in order. Im sure some of you have an idea what could cause this or how to disable this. What shall i logg to get a picture of what it could be?
I am suspecting IRL or IOP have something to do with this?

Why not just log the torque intervention path?
There's literally no point in guessing and NOT logging.

Could also be too rich mixture via LAMFA.
But yea, just log.

I mean, ME7L allows you to log just about EVERYTHING all at once. You don't even have to "decide" what to log. |

I agree.  When you're initially "debugging" a car - just log as many "representative" vars as you can, and then narrow it down and increase sample rate. At least that's what I usually do. |

Yes I know that But im running an ST10 Processor in my Me7.1.1 and Me7L doesnt support that wich SUCK BIG time... Maybe VCDS can log that.. but dunno what parameter i shall log.. Could these be found in VCDS? Or is ther any other method to logg these? EngineLoad EngineLoadCorrected EngineLoadRequested EngineLoadSpecified Another option is to disable torquemonitoring completly just to try and error.. Will follow this example. Table KFMIZUOF = 99.6% for all base points Z - 11619 * 0.390625 X - 1008E * 40 Y - 1166D * 0.390625 Scalar TMNSMN = -48 C 11676 * 0.75 - 48 Scalar TANSMN = -48 C 11675 * 0.75 - 48 Heres my LAMBDA i think it looks OK on E85 and high comppression |

Can not find KFMIZUOF in MDZUL in my engine.. They must have changed on the ST10 ECU´s crap... and more crap.. Working in the darkness as usual without propper logging tools.

I founds This MAP (KFMOF) Must be: KFMIZUFIL Zuläassiges indiziertes Moment zur Momentenbegrenzung vor Filter ??

Torquelimiter now disabled on all fronts... Still get this annoying short jerk... I have gone through lambda and suck things. Also increased dwell time a bit. Cant se anything in my logs..
I logged accel pedal vs Actual plate angle I couldnt se anything suspicious there.

i have that same problem!
I think it's fuel related. It only happened when i swapped in bigger injectors. Logs show a sharp spike in AF when it happens as well.

You can try playing with KFBALB/KFBAKL to smooth out load transition AFRs - if you're 100% sure it's injector related.
Double-check on TVUB too.

I'll look into that. I'm pretty confident on that due to the fact i swapped in these injectors brand new 2 years ago when i was NA, dialed them in, and i noticed the momentary buck back then as well. |

Well.. I realized i had to implement that map into my TunerPRo project.. now i have done so.. But im not sure how this map works? Faktor Beschleunigungsanreicherung (K+L-Anteil) Wich means Acceleration enrichment. At 90c engine temp for example it looks like i have less enrichment than when cooler engine. Do you suggest that I enrich a bit more here? Could be so since im running E85.. hmmm.. Ill try and se what happens I dont have KFBALB it seems.. only forced indiction have this i guess.. |
