Jb4 app not showing the gages working.

[Sean R]

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

Yes you must connect jb4 to car under dashboard left of driver with ODBIi provided with the jb4

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..
