  8. Re: Turning off tire pressure sensor feature in 20

    yes, I did. The only way to get this feature turned off in the programming is to take the car in to a dealer that has a Tech II. The feature IS in the Tech II, I know this for a fact. But I had to...

    Chris;

    could you clarify/reiterate how to disable the trims?

    could you also be a little more specific about the initial VE table tuning regarding how we aim to tune it to 13.0:1 with wide band,...

    Hot start issue in SD mode
