Electronic Control Unit (ETS ECU)

The ETS ECU receives information on a variety of engine parameters, which it processes before sending appropriate control signals to the throttle housing.
The ECU has an integral self-diagnostics function which is activated every time the ignition is switched off. On power off, automatic testing takes place of all functions and the latest adaptive values are added to memory.
The ECU monitors operation of the system continuously, and if a fault is detected that could affect safety, immediately switches to the limp-home function.
