Throttle and G's aren't starting at zero?

I just started using my VIRB Ultra 30 which is connected to an OBDLink LX scanner via bluetooth. In all my videos the Throttle gauge is at 18% when I'm parked or stopped on level ground. The Lat/Vert gauge also says 1G (downward) as if I'm accelerating as well. Is there a way to fix this or calibrate it?

Other info:
Firmware: 4.3
VIRB Edit: 5.1
Mount: Garmin suction mount to windshield, camera is upside but films rightside up, camera is as level as I can get it

Here's an example:
