I am looking for an ECM with the GM PROM Chip if possible for my 1982 Corvette. All the difficulties I have experienced with my car leads back to my ECM. I do not have my original ECM. I thought a 1984 ECM would work since both vehicles have the crossfire engine, but apparently not. Apparently...

I am in desperate need for an ECM for my 1982 Corvette. The OEM part number is: 1225550. Can anyone help?

I am struggling to understand how to use the forum on this site or any site. So if anyone can help me in that area I would appreciate it. The main issue I have is with my 1982 Corvette crossfire injection car. I have done everything I can think of and yet my car still won't run right. I have...

I have come to a dead end with my 1982 Corvette. I have done everything to get it running perfectly. I have replaced everything. The last couple things I just did was have my ECM checked out, which is was fine. Then someone on here told me to buy a fuel pump relay, which I did. I also bought a...

I have been asking questions and doing research. Apparently, the ECM back then didn't possess too much computing power or programming ability. Apparently, the programming is mostly in the PROM chip not the ECM itself. I didn't realize that. Another tech at a Chevy dealership here in Minneapolis...

I have replaced the engine coolant temp sensor. My OBDI is not working even though it was working last fall. I don't know why it stopped. I will check the fuses again. I did speak with someone at Summit Racing and he definitely said having a 1984 ECM with a 1984 PROM chip will reek havoc with my...

No intake leaks and the vehicle is perfectly timed and tuned. I have been told to check the grounds. They look good, but I need to look closer to make sure. thanks for the input. I and others think it is my ECM. Either the rebuilt ECM I have is defective or it came from a car that had a manual...

Initially my OBDI was working, but now it has stopped. Originally the only codes were 12 and 13. 12 is nothing and I believe 13 was dealing with an O2 sensor, which I replaced with everything else. And I mean I've replaced everything: plugs, wires, ignition module (twice), ignition coil...

I am new to this or any forum. I have a 1982 Corvette and I'm extremely frustrated. I have replaced everything imaginable to get it running smoothly. I recently replaced the pick up coil thinking that might be the problem with my idle and why the car suddenly just dies. Well, it wasn't the...

Thanks for the info. I had Cardone rebuild the ECM and told them my car was an automatic, but I do not know if the tranny was auto or manual with the original car that this ECM came from. I will try to look into it.

Hello, I have a 1982 Corvette. I have been trying to get this vehicle running correctly. I have replaced everything! I have had three different mechanics work on it. It now starts immediately and idles smoothly, but after a minute or two will die. This did not happen ever before today. When I...
