There are adjustments for tire size and gear ratio, but it only changes the shifting schedule.

So changing the tire size via SCT Livewire... when you say it changes the shifting schedule... does it also adjust the speedometer and odometer properly?? I was under the assumption that it did.

Is there anything out that will fix the speedometer for the 6.4L?

I just had my truck flashed at the dealer today and asked to check if the tire size could be adjusted and he said there was nothing in the program for that. All the mechanic said was give it time and that I should buy a programmer and not use a "chip" or "modual" because they don't control well enough. I think I just found my mod friendly dealer.
