i had an issue today with uninstalling the cobb tune because i had to goto the dealer. when i turned my truck back on i had a CEL. it said something about gear axle ration fault. is this a known issue with adjusting the tire size? does the update take care of that code? i reinstalled the cobb tuner and didnt adjust the tire size this time and the code is gone.
yes. However cobbs tuner interprets tire size and whatever the table is that they are changing the tire size in is different than the likes of MPT and everyone else in the industry.
changing tiresize using a different tool, then applying a cobb tune will cause a vin mismatch error on the dash. You cant clear it unless you reset the tire size back to 34.4".
Set the tire size back to stock and everything will go away.
