I just want to cover all my bases here but anyway I have a 1989 Chevy S10 4.3 liter that I put later year Vortec heads on, Performer intake and a medium sized cam in. I started tuning with the stock 1228062 ecm, which has proved to be pretty tedious and difficult with the engine set up that I have. I was told by someone else that I could swap it for a 1227747 ecm because it has more parameters that I can adjust to better fit my needs in tuning and has the same pin out as my truck. My question is.... am I right to be able to use this ecm as long as I obviously change the bin to start with one close to my engine? Is there anything else I need to change? I have exhausted the amount of research I could find on the subject and want to make sure I am not missing anything critical. Thanks in advance for all your help.
