AEM EFI starting & tuning (Gen3 426)

CruisinFNC,
I'm using the MP (AEM) ECM and harness for my build also. My engine is a 6.1 based 392, similar to your specs except for the c.i. of course. My ECU came with a CD that includes a few tunes, including a basic one for start up, along with tons of information and schematics.

I'm up in NorCal, S.F. East Bay area to be specific. We should definitely get together. Please PM me, let's exchange info and get together!
