0411PCM swap and 4x4
Well, I just went out and tried changing into 4HI and LO.
No problems. The transfer case engaged and disengaged as per normal CLUNK!!!
Took it for a drive around the block and it shifted up and down.
I guess this means the 02 Savana tune is fine with the 0411 PCM swap and 4x4's.
I didn't notice any issues.

YOU ONLY NEED TWO TOOLS IN LIFE - WD-40 AND DUCT TAPE. IF IT DOESN'T
MOVE AND SHOULD, USE THE WD-40. IF IT SHOULDN'T MOVE AND DOES, USE THE
DUCT TAPE.
IF YOU CAN'T FIX IT WITH A HAMMER, YOU'VE GOT AN ELECTRICAL PROBLEM.

Glad to hear that. As near as I could tell when putting together the wiring file for the PCM swap, the PCM doesn't control the 4WD. I believe the 2 wires that input into the PCM just change the shifting schedules and maybe pressures.
