I have a RX7 that is swapped with a 2000 firebird ecm and harness and we are 99% sure the ecu is bad. It is tuned with HP tuners. My question is can I take the ecu that I have on the shelf that was out of a truck(lq4/4l80e), plug it in, burn a couple HP tuners credits, delete vats etc, copy the tune over, and run it? I was told that I would have to have a dealer flash it to a 2000 firebird and go from there but that seems like an unnecessary step.
The hardware numbers on the ecu match. The car has a MVB trans so no ecu control of the trans.
Thanks in advance.

Yes you can do it, I have done it several times.
Ask the dealer how much they charge to flash it to a 2000 Firebird OS, it may be cheaper to do it with HPT.
Find a stock OS and burn 4 credits to flash, then copy over your current tune to the new PCM

it might actually be cheaper to do to the dealer than use 2-4 credits. they only charged me 77 bucks to flash mine back to stock. though it sounds like youre in a slightly different situation.

yeah, i was told that i can have the dealer flash it back to stock for $70 and then ill have to use two credits on it to tune it. I just dont understand why it cant be tuned the way it is, why does it have to be flashed to a fbody first?

The car will start and drive as it is, but some things won't work, like the fuel gauge, speedo and a few other. Some of that things you can fix them with tuning, but other things can't and they won't work
Is better to flash it to a 2000 Fbody OS
