LS3 PCM in 4th gen? Im sure its been done. Im just out of the loop.
Could anyone direct me to a how to or thread on experiences on running a 58x, drive by cable PCM in a 4th gen fbody ? Will it run stock gauges?
Ive got questions.
Lol

Well for starters no such OEM GM computer exists. Just use a Lingenfelter 58x to 24x converter box and use the stock PCM if your goal is to run an LS3 in your F-body and retain drive by cable. If you run an aftermarket computer then the sky is the limit and you can do whatever you want.
A 2002 Tahoe came flex fuel enabled and uses the same exact PCM, just segment swap or change out the whole OS. I've done it more times than I can count over the years and it's all over the forums. Or if you need a 3 bar OS with flex swap to P59 PCM, it's a simple swap and I did that way back in like 2016.

Yes, I've seen the Lingenfelter conversion harness. Heard its an ok option til about 7000 rpm, which i guess i really wouldnt be turning it much more than that anyway. I just was thinking that hopefully there was a this option to go with a newer and faster OE PCM. It will be procharged like my last set up.
I have to relearn the process because everything has changed so much. I built my car in 2006. Forged LS1, the only after market heads avaible at the time AFR,
motron 60 injectors. all ancient tech now LOL. D1SC,built t56, moser 12 bolt.
Then stopped keeping up on the new stuff.
