The thought has crossed my mind more than once as I pick through this EFI harness.

I followed my troubleshooting guide and it said "Replace Windsor with LS engine", not sure what that means??

It means we're doing it wrong...

Hopefully borrowing an A9P computer tonight to rule that out. We'll see. On Wade's recommendation also going to go over everything another time and hope I'm missing something stupid.

Fixes everything.

Fixes it so well... AI even said "stop it."

A9P has a different timing curve than A9L, if you decide to keep it you'll want a dyno cert with that EEC.

Yup... planning on just using the A9P borrowed computer to rule in/rule out my computer as failed.

Do your homework on the o2 harness before you switch computers, I think it fries leads on the PCB of the ECU if you go one direction but not the other.
Also, open your ECU and replace the caps, 2 out of 3 on mine literally fell off when I touched them.

This does ring a bell, but was that a MAF only thing? The details are fuzzy, but I do recall auto and manual having different O2 hrnesses now that you mention it.
