AEV Procal worked on my 2015 for tire size and TPMS eliminate.

 

Traildash is not compatible with the '15's. Only options are the DiabloSport '14 ECU swap, FlashCal or ProCal.

 

I bummed that you can't get the Flashpaq upgrade yet, I just bought the Flashcal when I lifted and installed my 35's on my 2015 last week. I am sure this has been covered somewhere but I couldn't find it and ended up here. Do you have to reset back to stock if the Jeep needs to go in to the dealership for an oil change or warranty work etc? I'm not talking about a performance tune just adjusting for the tire size.

 

No you don't have to reset it, though i don't know if that would be reason for the dealer to deny warranty work, which wouldn't be a surprise anyways.
I have the Flashcal to correct speedo, and the other little changes with the fog lights and what not, and i've taken the Jeep for oil change once and they didn't ask about any tuning loaded in the Jeep. I also have my own PCM tune loaded besides what Superchip does with the flashcal so my calibration is far from stock.

Also from what i've seeing, Chrysler is using a different approach to lock the 2015 pcm's, so the tools that worked in previous years to tune this PCM's won't work with the new stuff unless that restriction is removed. The tool i'm using to tune has support for 2015 Chrysler/Dodge/Jeep PCM's, we have no access to the trans portion yet (any year), but trans support is coming, and to remove the restriction in the 2015 models, there is a fee for it, which more likely is the reason Diablo or Superchips and others haven't released support for 2015 canned tunes.
