The target lambda is 14.7. I'm idleing at 850 rpm but lowest datalog lambda reading is at 1000 rpm.

Play with IAT and ECT Comp....I noticed that in cold weather...you may be idling at 850...but the the cells will be in column 3..4.5..instead of 2&3.

If you correct the IAT%...set it to lower % at certain temp. It will go back to where you have it when it was warm outside or when you last have a good reading.
