ECU Swap, 200 posts later...
Easy questions:
if I put the wrong ECU in a car, (correct model, but not programmed for that car), what happens? Is it:
a car immediately explodes
b all electronics render themselves inert
c the immobilizer light come on and the car will not start
If, after that, I replace the original ECU, what happens? Is it:
a the car immediately explodes
b everything goes back to working fine
I had 2, cloned, ECU's for the car. One I knew had a hard 610 issue, and one that was re-re-re programmed from old car. It has a temp sensitive 610 error. While getting a key made, I had the MSP16 flash done. There was a chance that their re-flash would clear up the 610, and it was open on the car. On the drive home it occurred to me that I may no longer have cloned ECU's and I need a way to test that. The only way I can think to test is to swap the two and see if the car starts. Hence, the first set of questions.
I am kind of thinking that the answer is along the lines of "no issues", or the dealer would fry a lot of cars. Just want to be sure.
Advice appreciated?

I imagine that the ECU reports its identity and that it check other modules' identities. So long as the ECU's identity is the same and other modules' identities are the same, I don't see why it wouldn't keep working.
