So I just installed my jb4 tuner and the app on my Samsung 10. The app will see the box and I can change maps, but the digital gages are not reading what the car is doing. I have the latest firmware.. Any idea thanks

OBD2 has to be connected before the gauges will work, there's a round rubber grommet under the dash by your left foot. Put a small cut in it an run the OBD2 wire through to your JB4, your gauges will work then..
