The reset your AP does after a map flash does not reset adaptations. You'll need a BT tool, or D-CAN cable with INPA (or a Procede/JB4) to reset the O2/lambda adaptations.

But in regards to altering scalar to get rid of mixture codes or rough idle, you're not the first person to speak of it. It seems to work.

Running 50/50 never have codes or an issue with the rev3 and dme flash. When I ran e80 I tossed mixture codes but only at that level. Car actually runs too rich for my bloom hitting low 11s and high 10s in the upper rpm range

I have jb4 and Cobb flash 100% stock fuel system and tuning 100% e85. Zero problems on any condition of start up no rough idle whatsoever.

I started my car a few nights ago after it had been sitting for 3 days and it was 19* started like factory.

I've only thrown a code every once in a while and I just clear it when it happens.
