I have my 2015 JKUR HR here. Had the Metal Cloak lift installed w/Fox IPF shocks and 35 KM2. Purchased a Diablo Trinity T1000 programmer to install so I could make the adjustment for the tires. The shop said they contacted Diablo Manufacturer and was told it was not compatible with the 2015s. Just wondering what others are using to calibrate the tire size on 2015s.

Not as fancy as the Diablo Trinity T1000 but the F4 Flashpaq Programmer is available at Superchips Part 3872 - F4 Flashpaq Programmer - Fits 1998 to 2015 Wrangler, Rubicon and Unlimited with 3.6L, 3.8L and 4.0L - 4 Wheel Drive

Ya i just ordered a Flashpaq 3872 from amazon, it was the cheapest site for $260 vs $350 from the other sites. The reason why i got it was becasue i was told by buddy that it works wonders on his 2012 JKU running stock. Ive just installed a lift and 35's and need to correct the speedo and run settings to get some of my mpgs back. Sweet ride BTW

Do you have the link for how you got it for $260? The one I see has like 40 something dollars shipping. Thanks.

I definitely concur with the mpgs and speedo being off. My aftermarket tires aren't as big as yours but they still threw the speedo off. I did get mpg after I installed an Rugged Ridge Air Intake, aFe throttle body spacer and Dynomax exhaust. I'm saving money for the Flashpaq 3872 and hoping this will increase my mpg further.

I have a 2015 as well, Diablo just brought out a ECM swap and a tuner solution, I don't know anybody that has installed one yet but Diablo has some huge claims about it and at 900 bucks it should! Unfortunately this is the only solution a programmer alone will not work because the ECM 's are too encrypted I'm being told by dealer this has something to do with Fiat being involved Chrysler now.

Do any of the cheaper (procal etc). Work on the 2015 ? Just looking to correct speedo and shift points for larger tires and eventually gears.....

nevermind..it specifically says they do.....I see now this thread was started a year ago

I've got a Superchips flashcal. There is an option to upgrade it via a download to a flashpaq. Problem is when trying to do that the program reports that it's not compatible with 2015. I could be wrong but I don't think Superchips has anything for a 2015 other than basic programming functions not tuning.

The flashpaq will not work with the 15's, only the flashcal. I'm sure they are working on it, but no telling when that might be. I'm in the same boat.

Superchips traildash for 03 - 14, I belive it will work on the 15 also. Just installed on my 2012 jk sport, 35's,4.56 gears
Has a lot of features, added around 20+ hp, really made a difference.
