Can someone please provide a definition of what the following Data Channels are:
Accel X

Accel Z

Thanks, have a great day...

I believe it's the readings off your phone's accelerometer so that you can see G-Forces.

Hey Pele .. thanks for the response, would you know what each of them represents, Lateral, longitudinal, Yaw???

I believe those values will change based on the orientation (Mounting position) and rotation (portrait/vertical vs landscape/horizontal) of your phone/tablet in the vehicle.
