CTIS pressure settings increase - no programming, transducer, or module required.

Heck yeah! Let us know what you find!

I have to replace the Pressure Transducer first so the system can read tire pressure again, then I'll start playing with it. Anyone know the PN for the P110 pins?

Do the M939 CTIS controllers work without modification in the LMTV A0's? I know the A1 can talk to it, but the A0 can't. Has anyone used one?

Since the A0 doesn't have a J1939 bus at all I would *assume* it would work without issue. The only issue with them on the A1 trucks is they burn out the J1939 termination resistors if you don't pull the pins out of them. Not having those pins doesn't affect their operation though - seems that Dana left some pins hot that they assumed wouldn't ever be used and those ended up being the pins they later used for the J1939 so it kinda broke the forward compatibility unless you know to pull the pins out or disconnect the wiring to them.

As @GeneralDisorder does, I *assume* the M939A2 CTIS ECU will plug and play in the LMTV A0 variants. Easy enough to check. Use the M939A2 CTIS schematic from pot#65 and match to your A0 schematic?
