Default ECM question

I am having a problem with my 93 6 speed car tha I think might be caused by the ECM under the hood. Can I swap the ECM from my wife's 93 auto trans car to troubleshoot? Thanks

Are you getting any codes? Is your wife's car anything close to your Vette?? Not very likely. You'll need the same ECM and even if she did have same one and yours is fried, you'd want to make sure not to fry hers too.

If they are both stock programs it shouldn't be a problem. The main thing I can think of is the speedo will be off.

Going the other way (M6 ECM in A4) could be a problem because it may or may not have the shift tables set up correctly.
