Simple ECM question: 305 vs 350
Simple ECM question: 305 vs 350
I just kinda posted this in another thread, but thought I would ask to the proper forum.
I have a mixed up engine- I had a 350 block put in my '91 Camaro, but some of the original (305) components such as the induction and presumably the computer remain the same. The car runs (ran- until today, but that's another story) okay, but I'm wondering what else I need to replace to make it a fully equiped tuned 350. I'm guessing the computer needs to be changed, but I'm thinking that maybe its only the eprom program that needs to be updated. The engines are similar enough that it seems likely to me that the physical electronics would probably be the same and only the programming of the chip would differ. Can anyone confirm or deny this? Also- I would like to rewrite the eprom to erase the speed limiter info. Where can I get the stock 350 eprom program? (with speed limiting removed, or instructions on what lines to edit?) Thanks for any help!
