    Does oversized tires make your Odometer inaccurate? If so is this fixed by a dealer tire size recalibration?

    What’s the biggest size a dealer can recalibrate for?

    @yz kid

    Sure it affects your speedometer, odometer, shifting points if you have an automatic and more..

    You DO want to address the issue asap. You can just go to the dealer and pay them the $125+- for the reprogramming but think twice before you do that.. do your homework so to speak before you do this.

    I suggest that you take the $125+- and instead buy a programmer. There are two programmers for the JL right now. The SuperChips Flashcal and the ZAutomotive TazerJL. Both are very decent offerings and both do the job you seek and more.

    Do forum search's using the words Superchips, Flashcal, TazerJL, ZAutomotive, programmer. Lots of info to read..

    There is even a forum poll that indicates how many forum members went with which particular programmer.

    Both SuperChips and ZAutomotive are forum sponsors.

    As a Rubi owner, I went with the Tazer JL. I'm thrilled with choice. 8-)

    Most guys unmarry the programmer from the vehicle and remove all traces of it from the Jeep before driving it to the dealership for service. This way, it's very unlikely you'll ever get asked about it.

    If your dealership is run by people who treat people poorly, there is a small chance that the programmer could cause you some issues if you have an electrical warranty issue or something that requires them to dig deep into the ECU, but that is rare and most guys never have an issue.

    Now, later on when programmers gain the ability to tune the engine for more power and change how the transmission shifts, that will be more risky. But the current crop of programmers only do a few little things, so they aren't a threat to warranty much at all.
