  • Correcting speedo (pinion angle)?

    How can I do this in Advantage? Only the rear tires size matters right? Factory is 255/55/17, now it's 295/45/20.

    TIA.

    You can adjust your tire size by adjusting "Revs per Mile" in the "Axle" then select "Scalar." Hope this helps.

        would I be able to adjust my speedometer with the xcal2 for a '96 Gen II?

          I've not seen a tire size adjuster in any of the truck pcm's I've gone through.

            It may not be adjustable in the dodge vehicles at this point.

            I will edit the post above, since it that is how the ford applications work.

              This is probably my most asked question with this unit. It would really be nice to get the tire size changing capability in the app.

                On Ram Trucks, this is in the brake controller. I change it all of the time with a Snap On Modis via enhanced OBD - it prompts for either a preselected few tires for that model or will allow you to specify revs-per-mile.
