ECU Replacement

[Captain RonJon]

If I purchase a used ECU to replace a fried one in my 2000 GSX RFI, as long as it's the same part #, can I just pull the old one out and plug the new one in? I had read it needed to be 'flashed' by a dealer, which they charge a lot of dough to do. However, someone I know said that's nonsense and that he's replaced a couple over the years and have always just plugged them in without issue. I realize perhaps the maintenance hours and code history would be wrong but who cares? So, is it plug and play?

plug and play if you have the matching key to the ECU, and they are generally sold together (but not always)

So far I've always seen the DESS key come with the MPEM not the ECU; does it matter?

sorry, I consider MPEM/ECU/Computer/Brain/Ebox one of the same. and technically they are not, my bad.

dealers usually charge $50ish to program your key, assuming your replacement MPEM doesn't come with one

Luckily my MPEM is good, so I can keep that with my key but I do need a replacement ECU - that's really my question - can I just pick up a replacement ECU and plug my MPEM into and it will work? Assuming my replacement is the same part #. Sorry for any confusion!
