IMU Location
This setting specifies whether the speed sensor will be
using its in-built IMU or an external IMU.
Note: This option is only presented when the IMU
integration is 'Enabled'.
Roof Mount
This setting specifies whether you are using a roof-
mounted IMU from Racelogic or not.
When it is 'Enabled', it will automatically add a 1 m z-
offset, translating the filtered speed down into the
vehicle towards the centre of gravity. The 'Ant to
IMU Offset' will become 'Ant to Ref. Offset'.
Note: This option is only presented when the IMU
Location is set to ‘External’.
Wheel Speed Input
IMPORTANT
Wheel speeds must not be used when conducting
brake stops!
This setting allows wheel speeds to be passed into the
Kalman Filter.
If the unit cannot detect CAN data, you will see a
Warning Message on the front panel.
Note: This option is only presented when the IMU
integration is 'Enabled'.
This action will add the Wheel Speeds channel to CAN
ID 31D.
Ant to Wheel Offset
This setting specifies the x,y, and z distances between
the antenna and the wheel speed reference point.
The reference point is the centre point between the rear
wheels.
You can find more information here.
Note: This option is only presented when Wheel
Speed Input is 'Enabled'.
Ant to IMU/Ref. Offset When Roof Mount is 'Disabled' - Provides the x,y, and
z offset values from the antenna to the Speed Sensor/
