Does Anyone Know How I Can Do This?
I have a 04 5.3 truck PCM (6242) and harness that I converted for installing in an old Camaro. My original intentions were to set up the 5.3 in the Camaro and after all the hard work was done, change the 5.3 to whatever LS engine I wanted. This engine had a LS1 intake and injectors with the 5.3 DBW TB and ran great. I sold that motor and bought a 02 LS6. I have it set up in my engine test/run stand with the 5.3 electronics (DBW/TAC, etc.) but am having problems figuring out how to tune the PCM to run with the 5.3 DBW/TAC/TB but, with a LS6 tune. Everyone I've talked to around here (Dallas) doesn't have a clue. Most say just run a 411 PCM with a cable TB with a LS6 tune but, I have a lot of work in the harness and want to use DBW unless what I want to do is absolutely impossible. Can anyone here point me in the right direction to figure this out? Thanks, Joe Webb

It sounds like you're trying to dump a stock LS6 tune onto the 5.3 PCM. I don't understand why you're not just tuning the 5.3 PCM. Seems to me that any good LS tuner would be able to do it no problem.
