    Easy install, got an error message, called them, got them on the 2nd ring. They gave me a new download in 1 hour. Plugged it in changed it to my 35″ tires. I’m so happy, drives completely different. Cheap fix, I was looking at doing a gear job.

    Worked really well on my 2015 Jeep Wrangler. Regeared from 3.73 to 4.56 and put 35s on. Car wouldn’t shift out of first gear after it got out of the shop. Used this and it drives and shifts perfectly now. Only took about 5 minutes too.

    I mainly purchased this product to recalibrate the speedometer on my 2012 Jeep Wrangler Unlimited (JK) due to oversized tires. Downloaded the update from site and registered product at the same time. Measured tires (surprising that 35 inch tires were actually 33 3/8 inches tall) which is in between the 1/4 in increments in the software. I used the 33 1/2 setting which gave me 69mph per GPS with 70mph on speedometer (was 66mph on speedometer for 70mph on GPS prior). This gadget has several other options (some ONLY for Rubicon model) and will read and clear trouble codes – but I‘ve heard a piece of electrical tape over the check engine light is a Jeep lover’s tradition lol. Overall, happy with purchase.

    purchased this after upgrading to 35” tires on my 2016 JKU. I noticed a HUGE difference in my drivetrain after rolling off out of the shop with 35” tires. It was slow to respond, felt a loss of power and I could tell that it wasn’t shifting where it was suppose to.

  5. Kevin g

    I took about 3 months doing research for the best system to change some factory settings and after thinking about it this is the best option. I’m really happy I went with it. I have tons of settings I can change but I’m not paying a car payment to get something so over kill its unnecessary. If you’re on the fence about this tuner I would recommend it. You’ll be happy

  6. Diana

    This tuner works great. Does exactly what is advertised. I was able to quickly and easily adjust tire size and turn off my pesky TPMS warning.

    However, if you have multiple Jeeps, it will only work on one at a time. If you have made tuning changes to Jeep #1, it will not allow you to tune Jeep #2 without resetting Jeep #1 back to factory default.
