best OS for 411 pcm/w 3bar, 80e, A/C, e-fans working on a swap and have a 411pcm that is currently programed for a 2002 avalanche with 5.3L OS 12212156.
combo will be a magnacharged 5.3L, 80e trans (segment swap required)
ill have 2 fans using high low in a series parallel configuration.
I want to be able to control the fans biased on speed, temp and a/c pressure
will the current OS do what I want or will I need to switch
BTW I was planning on using a 2004 express van compressor I have laying around

HD trucks of that vintage came with a 6.0 / 4L80E combo.
That could be a good place to start. Easy to change the
displacement. Express van diverged from the trucks about
that year ('03/'04, I recall we swapped a van PCM for the
blower truck PCM and they were very different, but I forget
the details mostly now). So anyway you want to look at
wiring, even though I'd bet the A/C compressor is still just
a dumb pump with a low side switched clutch solenoid.
