got the job done (mostly)

After a lift and wheel/tire upgrade, I needed to correct the speedo and turn off TPMS. The internet update was a pain (required to turn off the tpms) and took many attempts, with the resolution of un-installing the app and reinstalling to get it to work. But once it did I was able to recalibrate, turn off the speedo, and turn off other options, its worked great. Easy to read screen and simple scroll buttons make it easy to use.

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.
