Better than expected

I loved the easy of use. I would recommend this to anyone. I was able to calibrate my Jeep JL Speedo in less than 5 min.

Easy to use- wish it had more

So far I really like the app and Bluetooth connector. I do really wish the developer would offer an update with gauges- oil temperature would be the most ideal. I’m sure folks with an auto would like trans temp and pressure.
Worked great for changing gears and tires. The gps speed feature is awesome. Ran the highway for 30 miles and really narrowed down the tire size. It’s on the money- I have a uniden r7 radar detector and matched that speed exactly.
Overall great bang for your buck.

Simple to use

Fantastic module - wish there were more features to enable such as a trail camera and the addition of factory auxiliary switches.
