    Speedometer and Gear Ratio Support

    With the NGC3 support testing in full swing, what is the outlook on gear/tire calibration support? Is this something that has been looked into, at this point?

    Gear changes are done using the current 2.25 Beta Scanner. There is a gear change utility in the special functions section of the scanner for the DCX applications.

    Does this accommodate tire size changes?

    Yes. It currently supports gear and tire changes for NGC4, NGC4A, GPEC2, GPEC2A, and CAN based NGC3 (NGC3 CAN)

    I tried on my truck with 2.25.2720 and am getting a blank screen on the special function screen. I emailed support and was told that my truck is not a CAN based system.

    This is what my log files shows:

    I am only seeing gear ratio on this one, I need to check which one it is.

    Are you guys making progress on the non Can NGC3?

    Along with this, I see that some are advertising the ability for ESP stability optimization while doing tire size/gear ratio. Do you guys know how they are accomplishing this? If so would it be an option you would be willing to allow us to have?
