I have seven two zero Fiero ECMs I would be happy to part with for $25 + shipping (or you can come pick 'em up), since it's extremely unlikely I'll ever be going back to a stock Fiero engine in any of my cars. All of them worked when removed, may or may not contain a PROM, so keep the one out of your old ECM.
First up: QTY 2 of the '6869 ECM, which is 85 Fiero V6. These are the ones that people used to use to go turbo, since you could re-burn the chip to a 2 bar MAP configuration. I don't think very many people do that anymore, but these are still good replacements for a stock Fiero V6.
Second: QTY 2 of the '6156 ECM, which is 84 Fiero 4 cylinder.SOLD Third: QTY 2 of the '7748 ECM, which is 87-88 Fiero 4 cylinder, also fits same year Grand Am 2.5, etc.SOLD

One ECM has a DDB PROM for the M19 4 speed (4.10 gears) One ECM has a CLM PROM for the MD9 3 speed (auto) One ECM has no PROM at all, as I sent it to member on PFF a few years ago to help get his car running.
I don't have a stock Fiero to test these on, but I'm pretty sure they all work. The CLM unit came out of the Indy that Jeff and I recently converted to a 5 speed, so it was working as recently as Thanksgiving. I suppose at $25 for two, there's not too much financial risk.
Edit to add that popping the chips out is no big deal as long as you're careful- they're in a plastic carrier that goes a long way towers protecting the PROMs pins.
