86 IROC with 350, which ECM to use?
I have an 86 IROC and bought it off of someone that installed a 350 in place of the 305 TPI. I don't know what cam he used, but as I started to replace the TPS, IAC, and MAFS the car actually ran worse than it did before. I hooked up an AutoXray this weekend and it came up with a trouble code 33, which stands for too much air entering the MAF. I understand the computer is configured for a 305, but was wondering if I could get an 87 and up computer or chip out of a 350 car, or would the dealer be able to help me? I'm new to the site and think it's awesome, plus I would like to say thanks ahead of time.

1986-89 305 & 350 TPI all use a 1227165 ECM. The only difference is the EPROM or chip.

That is BS. Go to another dealer & ask for an eprom for a 1986 Camaro, L98 engine, Auto Trans or Email me & I'll hook you up with the number.

Thanks for the info, but I went to another dealer and got the EPROM for $37. I really can't tell you if it's better because the car has a short that I'm trying to track down.
