A fellow who works next door to my house needs an ECM for his 86 Camaro, MPFI V6 auto. I have an un-needed ECM from an 86 Firebird, MPFI V6 5-speed. Just wondering if they are interchangeable enough to work; and what, if any side effects could be expected. Also what a reasonable price for it would be...

Thanks,
Pete

He'll probably need a different PROM, or use his old PROM for the automatic tranny with the TCC lockup. Also I believe the 85 and 85 ECMs are different in TPI cars, not so sure about the 2.8 V6's though.

"Take that auto, drop it in first, hold the brakes, stomp the gas and grin from ear to ear! :-)

 

ECMs should be the same, with different PROMs. Call Auto Zone to verify that they are the same & to get a price for a new one.
