    With 4.10 gears and 7 tooth with a 21 tooth driven gear the vss mph is reading 8% too high in logs. DCBIAS is at 3. Can it correct the mph in the tune?

    No
    VSS is an input on the 98 and older ecus. Its not an output like the 99+ ecus so it cannot correct the speedo.

    You can very easily write code to create a vss output if you are familiar with intel programming. It would be pretty simple.

    Speedometer is gps. I was just wondering if there was a multiplier to correct mph that the ecu sees from vss. I guess it doesn’t really matter anyway

    thats the pulses per mile you can edit it to make the logged value correct.
