Electronic control system
The electronic control system enables the engine to be
more efficiently and economically controlled. It is made up
of a number of sensors, switches and actuators around the
engine, all controlled and analysed by the engine control
unit (ECU). The ECU processes the information it receives
to control the fuel injection, ignition timing, over-revving,
alerts, idle speed controller (ISP), knock (F115A only) and
fail safe functions.
The graphic below gives an overview of the electronic
control system.
