Thanks for the reply.

I did read your guide early on, but it has been a while... reading through it again now.

Why did you need a 4g63 ignitor? I did not understand that... I built my MS2 with BIP373 coil drivers, and I'm running the stock 420 coil. It fires nice it seems, so just curious why you needed it. Maybe logic level spark control w/o bip373s?

For my install, I did have both CLT sensors hooked up, the GM one to the MS ECU and the stock one back to the Factory ECU.

At the time of testing, I did not have IAT or MAP hooked in, because I did not think they were needed (I noticed this at the end of my test session, I was out of time to test with them).

I also notice you tapped TPS to both ECUs? Does the stock ECU need it to run 4 functions I mentioned above? (no fuel or spark anymore)

Next time I get some time to work on it, I'll run my OBDII scanner and sort through the codes for any that might be relevant.

TPS sounds interesting, I'm curious if that being 'out of range' would make it angry, though I'm not at all sure why it would really care.
