What do I need to do to use an ecm off a 4.3 v6 on a v8? I have been searching and searching and I found one thing that says just need to swap both chips with ones from a v8? I have another ecm that came off a a v8 truck and has a hypertech chip in it but it apparently isn't a very popular ecm cause I found little info on it. So I just went to a junkyard and took the ecm from a truck with a v6 thinking it wouldn't matter. Now I read somewhere that it wont work? Im confused. Please straighten me out! Thanks!
