" Nah wait for the new Cabrera or whatever it will be called to come out. "

" I vote for COBB AP, HPFP upgrade, Set of wheel of winners picking (APEX would be good), BMW electronic performance steering wheel, CSL trunk lid, P3 gauge, OSS headlights, or LCI taillights.

Maybe let the winner choose from a number of items. Or have a set of three and have 3 winners that pick in their order (1st, 2nd, 3rd). "

" Apparently INPA can because I was able to fix my issue. As I understand it now, the DME looks at the post cat o2's and uses them to calibrate the pre-cat o2 with the long term adaptations. "

" No I haven't heard anything from them in a while. Yea, initially Shiv said that it was long term adaptations that the Procede couldn't reset and I would have to have the dealer reset them (that or it was the injector seals).

Hoping to get my secondary cats cut out later this week and 1790 vibrant resonators welded in... then to the dyno.

Also a shout out to @vasillalov for the daten files! "

" *Please no tuner war, Shiv hate, etc. in this thread. Just looking to get this issues resolved*

I have recently been having issues with a delta between banks 1 and 2 for AFR and fuel trim. The richer bank has a higher fuel trim, so the DME is intentionally making it richer. Looking at old logs, this started after I replaced both O2 sensors. Talking to Shiv he thought it was either long term adaptations causing it or old injectors having a bad seal (this was eliminated after a compression test [one bank was replaced under warranty 20k miles ago.])


So today I went ahead and cleared lambda adaptations with Inpa. No luck. So I then reset ALL adaptations with Inpa. After the first restart I got a DSC error and 500-1500rpm repeatedly (learning TPS). I restarted it & it idled fine, but AFR was constant(not reading). I restarted again and the AFR's were the same for ~10 seconds then the delta developed again. With the Daten files loaded I couldn't read my injectors so I just updated my Daten. Now there are additional adaptations listed that I will reset those tomorrow and see if it makes a difference.


Hopefully someone will have some insight into what may be causing this... I could try replacing the O2's again or the injectors, but hopefully it can be fixed via INPA. "
