Title: me7.5 weird specified fueling request Post by: dreconx on December 22, 2022, 02:59:00 PM hi guys,
im struggeling with a cupru R BAM engine, car has hybrid turbo and fmic/downpipe. I have done alot of these in the past but i cant figure this out. Ecu request 0.9lambda on idle?? Then when doing a pull its requesting 0.65 lambda ??? I tougth i did something wrong in the map so i put it back to stock and it still doing it. Some examples: Here is a picture of WOT run..

Car has no vacuum leaks. I hope you guys can tell me whats wrong here. Kind regards Yelle Title: Re: me7.5 weird specified fueling request Post by: terminator on December 22, 2022, 04:45:42 PM LAMBTS

Try to zero it. Title: Re: me7.5 weird specified fueling request Post by: nyet on December 23, 2022, 11:07:33 AM DLATRNLN Try to zero it. What is this? Should it be documented in the Tuning page? Title: Re: me7.5 weird specified fueling request Post by: terminator on December 23, 2022, 01:35:08 PM What is this? Should it be documented in the Tuning page? I know for sure it enriches AFR at very high loads(temp?) and I think it applies only for 2.7T and TT 225hp since they have EGT sensors. I don't know the reason why because it was many years ago so I didn't disassemble the file and there was almost no description in the FR. The AFR was around 0.67-0.7 and I solved my problem by zeroing this map. Translation: "Delta Lambda in Emergency Exhaust gas temperature control". B_atrnl is a trigger.

BTW, dreconx please obey forum rules. It isn't hard. https://nefariousmotorsports.com/forum/index.php?topic=12361.0title= Don't be that guy. It's annoying as fuck. Title: Re: me7.5 weird specified fueling request Post by: dreconx on December 23, 2022, 02:01:34 PM Got it. I am sorry nyet, i am so comfortable using vcds and did not know this was in the rules. Next post will use me7logger! Thanks for all the response BTW, dreconx please obey forum rules. It isn't hard. https://nefariousmotorsports.com/forum/index.php?topic=12361.0title= Don't be that guy. It's annoying as fuck. DLATRNLN Try to zero it. Thanks bud this fixes it. Title: Re: me7.5 weird specified fueling request Post by: Blazius on December 23, 2022, 06:11:28 PM Have you actually checked why does it trigger it in the first place, I mean its the whole reason for the ATR it goes off egt vs afr to keep EGTs in check if you hit the critical stage, which you probably did.
Title: Re: me7.5 weird specified fueling request Post by: nyet on December 23, 2022, 09:33:33 PM Agreed. Numbing ATR seems to be a very bad idea.
Title: Re: me7.5 weird specified fueling request Post by: tom-k on December 24, 2022, 05:38:09 AM DLATRNLN It`s not god way for this.Try to zero it. Adjust DLATRNLN for proper lambda (remember that the value in this map should correlate with your set value in LAMFA) AND adjust TABGSS just AFTER CHECK why ATR module change your fueling Title: Re: me7.5 weird specified fueling request Post by: nyet on December 24, 2022, 10:56:00 AM Well, he could zero it to narrow down if it is ATR. But ya, not more than for just that.
