Diablo Trinity with 1r13d crom does not work on 2014 JKURs. You will not be able to change gears, tire size, or tpms. Diablosport is supposedly fixing this but I'll believe it when I see it. I asked tech support to downgrade as my tuner was on a previous version that did work prior to upgrading to the latest and was told no - go to the dealer to have my jeep tuned if I needed it in the meantime and sell my tuner if I couldn't wait. Classy operation.
