Selector switch inputs



Auto transmission gear selector A = L.

Auto transmission gear selector B = 2.

Auto transmission gear selector C = D.

Auto transmission gear selector D = R.


If the common terminal is GND, any DINx can be used.

If the common terminal is +12V (stock configuration), DINx where the pullups can be disabled, or 0-5V AINx must be used.


Example input configuration in MTune

Speedsensor wheelspeed rear = Driveshaft sensor (VR).

Gearbox oil temp sensor = Any Temp AINx.

Brake pedal/stop light active.

Auto transmission manual mode switch (optional).

Transmission DOWN shift (optional).

Transmission UP shift (optional).
