need help with ecm upgrade for engine build
Not sure what you mean but maybe you want a tuner like Hypertech. This is not an endorsement though.
This a hard one cause it all depends on just what you are going to do to the engine, a reprogrammer might be the way to go if your don't get too radical with the mods, I suggest you visit your local speed shop, tell them what you are going to do and what they suggest, sometimes you have to send out the ECM and have the main programming totally redone to match the mods you have done to your engine. Remember power costs so none of this is going to be cheap.
Once you get your engine specs, there are companies out there to tune the computer for your engine. Here is one for you to check out... ExaTorq Tuning and Performance, 888.873.8012. Also this is not an endorsement.
OK appreciate the info will see what I can find, as far as hypt tuners the prob I've been told is the 96 thoese tuners will not work, bought only one they sold from a speed shop fast flah, but its very limited to what I can adjust ....motors already built, and just recently rebuilt with a bore to .030 os , has the gm performance "hot" cam p#24502586, 373 locker rear end, exhaust
