Sensors and calibration
Wheel speed (front/rear)
This menu gathers the wheel speed (front and rear) reading setup.
In the first screen, set if the reading is through FT500 sensor input
(white wire) or through FuelTech GearController CAN port.

If the chosen option is “White wire”, the configuration screens will be
shown to set the sensor input to left and right wheels, and number of
teeth. The next screens will not be displayed when the CAN option
is chosen.

The last setting is related to tire type and size. Slick/Drag Race tires
only require the wheel rim diameter. Radial tires require wheel rim
diameter, tire width and height.

15.7 Driveshaft RPM and Input shaft RPM
In the FTManager, there is a menu with all the settings related to
driveshaft RPM and input shaft RPM reading. In the touchscreen, the
settings are divided in a few submenus and will be presented in the
next chapters.
15.8 Driveshaft RPM
This menu is used to setup the driveshaft RPM reading. Select the
FT500 sensor input to be used and insert the trigger wheel number

With the driveshaft speed and the tire dimensions, it is possible to
calculate the traction wheel speed. If you want to use a driveshaft
RPM sensor instead of a wheel speed sensor, check the box “Calculate
wheel speed” in the next screen.

Differencial ratio
This configuration helps
to calculate wheel speed
using the differential ratio.

This feature allows the gearbox input shaft RPM Reading.
The reading is very useful to analyze the clutch/torque converter slip.
