MM3 Tuner - TPMS?

[Dodger]

Quick question.

I recently got an MM3; how do you change the TPMS threshold using the MM3?

I know the newer ones have this feature, but I’m not 100% sure mine has that capability.

From the gauge screen, touch the screen and select Main Menu, and from that screen, choose ECM and select TPMS.

I haven’t ever used it; see post #8 in the link below for entering high and low settings.

Also, I believe pressures need to be entered as 35.00 for 35psi.

Please keep us posted on your progress.

Thank you, sir.

The mission was a success.

Just a heads up, the truck must be in the “run” position, NOT running, to change the setting.

I did it while my truck was running (rookie mistake,) and the truck shut off and restarted by itself.
