Question. I have a 91 z28 with no ecm in it. I have a 91 305 tbi car that I am strippng for parts. Can I remove the ecm from the 91 tbi car,remove the memcal from it and use it in the 91 tpi map car? Are the connections at the ecm the same. I'm sure that I would have to remove the tbi memcal and swap in a different one and burn a new prom.Can someone recommend a base bin to start tuning a 383 and a t-56 trans. Some type of corvette bin I assume. Any possible wiring issues?Thanks

 

No... The ECMs are completely different, and not interchangeable.

 

Thanks!
