Check the ECM part numbers.
If they match you could take the chip from the corvette and pop it in the ECM.

I'm guessing the part numbers may not match and you would be SOL.
The 92/93 vette computers are scarcer than hens teeth

Good luck

It will work if the camaro had a LT1 in it. Part number on it should be 16159278.
Just remove the camaro memcal, and install the Corvette memcal and you should be good to go.

I know it works on 94/95 cars so it should work for you as well.

Not sure though if memcal has to be swapped or not? I know with 94/95 you can just plug the fbody PCM in and take off, though you will get a SYS light on your dash - you are probably going to get that as well, just an annoyance more than anything.
