3.1 has a '7730 ECM (MAP), the 2.8 ECM you listed is MAF, just be aware that there are 2 different harnesses.
I would suggest using a '7730 and there are plenty of harnesses for V8's on ebay for them. -
too bad you dont need an OBD2 L-body engine harness, i got one from when i was gonna do the swap on the Z26.sigpic

I thought the 7727 was simply the weatherproof version of the 7730?Originally posted by ForcedFirebird View PostComment

the 7727 uses 4 plugs compared to the 7730 using 3. they can be used in place of each other. uses the same tunes, just different connectionsComment
