The multi-function variable resistance potentiometer can be configured in the software to perform numerous features. These features include making changes to the fueling, ignition angle or adjusting the launch RPM without having to connect a laptop computer.
Operation
The POT is a variable resistor normally around 5K ohms. The signal voltage varies as the wiper moves. It is connected to 5 volts from the ECU and then the wiper signal will produce a voltage between 0 and 5 volts, proportional to the angle of the throttle plate.
