Thanks for sharing that with me.
That's a lot of info you put in that thread.
I'm actually using a P59 computer hardware #12583659. It came from a 2004 Astro van.
I'm just looking for anything that will run my 4.0L Jeep engine and be reliable. The 30+ year old Jeep wiring is junk. And of course it's not OBD2 so it can't tell you what's wrong.
I picked the P01 and P59 because I have PCM Hammer to read and write to them. I use TunerPro RT to modify tunes.
I'm going to be looking at the other 6 cyl GM systems because I have two other Jeeps I want to fuel inject. So the info you posted will probably be useful.
