I can't find anything in the help menu that gives more information on these tables. Under speedometer the Vehicle speed output and wheel speed output. Are they used to turn on vss speed outputs to run an aftermarket speedo. Or to the transmission computer to choose different inputs. I have a transmission swap that is shifting funky. Had to change the vss to 70 p/rev just to shift half dcnt. Need to get it fixed. 6l80to a 4L70.
