hello guys,
I'm not skilled on diesel, more on petrol...
I see the tire size wizard is not there... how about properly adjust speedometer and tire size / transmission shift point?
all manually?
thank you

Speedo>Calibration>VSS Pulses Per>#new number#
SO 28 inch tire to 31 inch tire #Old Tire Size# / #New Tire Size# x #Old VSS Pulses Per# = #New Pulses Per#
Trans>Shift Schedule
All there on that tab.
try normal first.
I know this is semi old. I finally bought a tuner and went to adjust my tire size. I'm confused on why the ecm has 3.72 and tcm has 4.10 as final drive ratios? Shouldnt they match?
