All Cannondale models use advanced fuel
injection systems. Engine operation is supported by
an Engine Management System (EMS) which
controls both ignition and fuel delivery. The system
consists of three types of electrical components: an
Engine Control Module (ECM), sensors, and
actuators.
The engine control unit (ECU or ECM) precisely
calculates ignition timing and fuel delivery for all
engine speeds and loads (based on the currently
installed calibration file and its mapping). The ECU is
an extremely reliable component and should be the
last component checked in the event there is a
problem with the fuel injection system.
The sensors of the system collect engine
operating information and transmit it to the ECU.
Actuators are devices like the fuel injectors, fuel
pump, fuel pressure regulator, spark plug coil, and
relays.
