BMW E90 M3 - Lean Lambda at WOT
Posted: Sat Jan 23, 2021 1:23 am
Hey fellas,
I apologize as I can't provide any data logs because my ECU is pass controlled and I can only view errors.
So the setup is as follow :
S65 V8 - 6MT - Supercharged -E85 - Meth
I'm having an issue with pre cat o2 sensors dying in every 2000kms or so and it always one of the banks & never both sides for some reason, and I'm asking whether this might mean that my S6+ unit is faulty or not
the car won't through an error till I hit WOT, and when the error is cleared it will drive normal till the next time boost goes beyond 0.2bar at full throttle.
I'm really sorry as I don't have any tunning background whatsoever and I'm trying to explain the problem as I experience it driving my car ... I know for sure o2 sensors shouldn't die every 2000 km and I'm starting to think that I might be having a faulty ECU ... can I have your feedback on this, please?
