Are the AFRs in the 10's with the AFM plugged in and the no-AFM map loaded? If so, it's normal for the AFRs to be off because you have the wrong IAT correction.

What MSQ did you load when you reflashed it for the no-AFM settings?

Looks like it way to rich to run with AIT. make sure you dont crank to much or you may wind up fouling your plugs.

Please email me your MSQ file and I'll take a look. Also, do you have a data log of it cranking / idling, however poorly?
