If you've increased your tire size on your Jeep JKU you need this calibration tool. Set my tire size to 35" and the transmission now shifts when it's supposed to. And the speedometer is now correct. Took all of 10 min. to calibrate

Reliable and easy to use. It's also up-gradable, I updated mine to a flashpak. Now I cant change the tune as well as calibrations like tire size, gear ratio...

Does what I ordered it for and more. On my Rubicon it locks axles in high range even in 2X.
I definitely recommend.

If you are running bigger tires you need this! After putting 35's on my JK my MPG when south and I found that I was driving about 10mph slower than what my speedometer was showing. After reprogramming with this my mileage is back up to what it used to be.

Easy to use, essential for newer Jeeps, update it BEFORE you use it, performed flawlessly.

Does what it says. My speedo is now accurate again and no more annoying TPMS warnings.

upgraded to 35 and I was doing my research. Some says that I would need to change gears....then I, came across this. It was a game changer! My transmission was confused when i changed to the 35's before programing the Jeep's computer. After plugging this in and programming my Jeep's computer...Went back to normal. Must have if you are replacing/upgrading to bigger tires.

5 star overall on the product for what it is. However, it doesn’t have the performance tuning, MPG tuning or other features the FlashPaq has. I made the mistake of reading the product description: “Upgradeable online to award winning features” to mean you could buy this one to save money then upgrade online to the full FlashPaq capability if you needed to. I now want to and it doesn’t seem you can. Anyone know for sure?
