Electronic Control Unit (ECU)

The engine ECU (1) is an electronic digital microprocessor-based unit.
It controls both the injectors and the coils, thus controlling fuel injection and ignition in accordance
with the engine operating conditions detected by the following sensors:
- Absolute pressure sensor (measures atmospheric pressure)
- Air temperature sensor (measures intake air temperature)
- Engine temperature sensor (measures coolant temperature)
- Timing/rpm sensor (measures engine rotation speed and cylinder timing relative to TDC)
- Throttle position sensor (measures the throttle opening angle).
The ECU also monitors battery voltage so that it can adjust injector opening time and ignition coil
charging time accordingly.
The ECU determines the following values:
- Amount of fuel delivered to each cylinder with a sequential non-parallel control
Injector closing time and therefore injection timing relative to the end of the induction stroke for each
-
cylinder
- Ignition advance.
Important
The maps, which include ignition advance values, injection times, crankshaft angle for injector closing
and all correction curves as a function of temperature and atmospheric pressure values, are stored in
the Flash Eprom of the ECU. The above values are preset by the Manufacturer after testing the
motorcycle under different riding conditions. These settings cannot be changed.
CO content can be adjusted using software on the DDS tester, which should be connected to the ECU
diagnostic socket.
For this procedure, refer to Sect. D 5,
There are two types of ECU connector, one has a grey terminal block (Telaio-Body), and one has a
black terminal block (Motore Engine).
