I have adjusted for gears and tires on many different LS1 and LQ4 trucks but this Duramax truck has me scraching my head. On the others I just changed the tire size and the program recalculated the VSS pulses for me but not on the Duramax program. How are we doing this? What do I change to make my speedo read right?
Thankyou, Tom

Things are still a little cloudy but that might be the piece of the puzzle that gets me back in the ballpark.
Thanks programmer, Tom

After i changed the speedo i also had to multiply all my transmission shift point tables by the percentage of tire size increase IE: i am running 315 70 17 that are 12% larger thanks stockers

Yup I'm figuring that out right now, I need to firm up the shifts also.Originally Posted by atver300
