I am sending Jim all three computers and he is going to use a different program for the tune
If CalEditor is right, the test computer has no IAC drivers, my original does, and the 2001 computer has to have them

I use a 12586242 as a test PCM. I installed it in a 2004 C1500 4.3L. The truck started. That was the issue, but the Idle slowly went up.
I personly like the 1mb PCM's, but most of the info I have is on them.

well neither computer will change the IAC position, both have the same tune exactly. He thinks something is wrong with the tune, so he is going to put a different tune in my original computer

Are you the PCM is right for the job? Some PCMs have
the IAC driver circuitry missing.
Measure each IAC phase to GND with a DMM with the
engine running, poke through the insulation with a
needle & clip-lead. If you see less than 100mV on all
of them, the PCM isn't trying.
Ran into this on an '04 Silverado AWD doing a big cable
TB swap, had to go to an '03 Savana PCM.
