    I changed tire/wheels from 22.5 to 24.5 and need to recalibrate speedo. Cant find instructions anywhere. Speedo has 2 8 contact dip switches, the pulses/miles is set by the first 8 positions of switch 1 and second 2 positions of switch 2. All switches are off, probably from factory. Lineset is A-2733P. Any way to recalibrate from these dipswitches?:biggrin_2557:

    That is all calculated in the ECM. You need to go to a shop that can connect to whatever engine you have and change the settings. Usually pulses per mile, but they will know. Those dipswitches are for trucks with mechanical engines.
