Hey guys. I have been doing some Datamaster logging, and, with this recent log, during full throttle, the o2 is showing rich, and the blm`s go lean.
Anybody else ever encounter this? And what could be the cause?

 

The BLM is lean prior to going full throttle. Once in PE mode BLM learn is off. So the BLM value won't move, although since it is less then 128 the ECM won't use it while in WOT.

If it was > 128 then the ECM would use it during WOT.

RBob.

 

Thanks!
