Hey guys, I have an 85 iroc TPI equipped with the stock(slow baud) ECM that is apparently a real pain in the a** to tune and burn chips for. My plan so far is to repin and swap my ECM for a faster baud 86-89 ECM, then to send it out and get a flash system installed so I can tune on the fly without messing with chips(I think flash should pay for itself in the long run).

So I read alot of tutorials and information regarding how ECMs work and this great guide in the tech section: http://www.eecis.udel.edu/~davis/z28/ecm_swap/

Now my question is, do i HAVE to use ECM # 1227165 for the swap? Is that the ONLY ecm I should use for the swap, or is it possible to use ones from the V6 thirdgens, or say a V8 TBI Caprice? From what I gather I should stick to a donor ECM from a V8 TPI thirdgen with MAF from 86-89. But has anyone successful used any other types of computers instead of 1227165 for the swap?

I ask this question because I actually have a #1227302 ECM lying around from the junkyard, it was out of a V6 trans am and I wondered if this was usable. Hopefully you can set me straight and shed light on this subject for me, thanks guys!

 

you can use any 1227165 ecm, but you need to get a memcal from 86-89 305 or 350 TPI (camaro or firebird)
