I thought I remembered reading where someone had replaced some older ecms with newer ones that could be tuned with efi live. I think they may have even made a chart?
I don't have all the specifics because this was just mentioned in passing, but a guy asked me if efi would work with a 94 yukon. I told him no, but you may be able to swap the ecm with one that can be tuned. I don't know what motor he has or any other specifics, but my question is is it possible to swap that pcm with a newer one with little trouble?
