Is there something that we need to adjust on the computer if we are
running
different size tires, or is this just for calibrating the speedo??
Since I
put the 33's on my truck, my speedo is 5 mph low, but seems to run the
same.
Anybody know??
John,
DRB3 is the mopar dealer computer. It's what they use to program in
the VIN and mileage. So, I figured why not just ask if they could adjust
my mopar ECM for the smaller tire size. OE tire was 28.04" the new tires
are 25.66" and OD error was 9.28%
higher. Jim at Carl Burger Dodge reprogramed the computer for the
smaller tire size.
I didn't want to mess with the speedo gears.
