GREAT Product...very easy to use.

Reviewed By Joshua R (STREAMWOOD, IL) Reviewed for a 2013 Jeep Wrangler —7/11/2014 5:02 AM

I have been running 33" tires instead of the stock 31" for the past year, and the shifting of the transmission was just not right in terms of shift points. I knew that with my plans to switch to 35" tires in the very near future would further amplify the issues with the shifting as well as traction control. So I bought this device to bring everything back within spec. It really did work well. I look forward to using it again next week when the 35's are mounted.

If you have changed the tire size or gear ratio in any OBD II vehicle, this unit is a must. I went from 32" to 35" tires. My speedometer, odometer, and MPG computer were off quite a bit. This unit is incredibly easy to use. Find your OBD port, plug it in and follow the instructions presented to you on the screen. You're done in a few minutes, and your vehicles computer has been re-programmed for the proper tire size and gear ratio.
