    Turn your temperature blending back on (set B0109 to 'Yes') and restore {B4901} and {B4902} to factory values.

    So I give up. This thing still after a month of messing with it daily. I can not get it to maintain afr from one day to the next. Some days it may start at 15.5 and get to 13.8. Other days it may start at 14.6 go up to 15.2 idle there for a cpl mins then drop to 13.2. Anybody have any other ideas im ready to throw in the towel.

    Post your current tune file and a log of the current tune with the AFR fluctuating.

    Okay, now do another log for me.... this time when you start the engine up and start logging, I'd like you to tap the throttle just after you start logging and then log the idle for 5-10 minutes.
