The EPC system 950 Supermoto
Mode of operation:
Battery voltage from the battery flows to the ECU (control unit)
emergency OFF switch
and the alarm system control unit (if installed, otherwise through the dummy plug
2
The EPC valves
are supplied with battery current via the emergency OFF switch, the ground (red/green cable) is switched by
5
the ECU.
The ECU receives a ground from the gear sensor
two gears is engaged.
If the throttle grip is opened all the way (which the ECU recognizes via the TPS
revolutions) in 2nd or 3rd gear, the ECU activates the ground control of the EPC valves.
Subsequently, the EPC valves will open an air connection to the carburetor diaphragm covers. A controlled amount of fresh air
can be sucked into the space above the diaphragm, reducing the vacuum over the carburetor diaphragm.
This causes the carburetor slides to open more slowly resulting in a lower air-gap area to be sucked in through the engine. The
engine performance and noise are significantly reduced.
NOTE: if the EPC valves are disconnected, this will not influence the other systems.
