ELECTRONIC CONTROL UNIT TYPE I.A.W.16M «2» - Fig.12-05
The electronic controller of injection-ignition Weber system is based on a microprocessor that optimises the
following parameters:
- optimum fuel quantity for each cylinder in the right sequence (1-2) in the same feeding duct.
- right injection phase in relation with the induction of each cylinder.
- proper ignition advance which is calculated with an algorithm based an the following parameters:
- absolute pressure
- temperature of the air induction
- oil temperature (for the SPORT 1100 l) or engine temperature (for the DAYTONA RS and V10 CENTAURO)
- R.P.M. and phase of the engine
- battery voltage
- throttle position.
Security adhesive «3» -Fig. 12-05
Absolute pressure transducer «4» -Fig. 12-05
This transducer is powered by the electronic control centre and gives information about the absolute pressure
in the air filter box.
This transducer is connected to the filter box through a small pipe. Its output signal will produce a correction signal
as function of the barometrical pressure.
Air temperature transducer «5» - Fig. 12-05 / Fig.12-06
This transducer gives an electrical signal which is a function of the air temperature.
This signal is fed into the electronic control centre and will produce the correction factor as a function of the air
temperature. The transducer consist of a NTC thermistor with a plastic capsule.
In order to avoid damages to the transducer it must be mounted with the right wrench setting torque.
Oil temperature transducer «5A» - Fig. 12-05 / Fig. 12-06 (Only for SPORT model 1100 l)
This transducer gives an electrical signal which is a function of the oil temperature.
This signal is fed into the electronic control centre and will produce the correction factor as a function of the oil
temperature. The transducer consist of a NTC thermistor with a plastic capsule.
In order to avoid damages to the transducer it must be mounted with the right wrench setting torque.
Engine temperature transducer «6» - Fig.12-05 / 12-06 (only for V10 CENTAURO and DAYTONA RS)
This transducer gives an electrical signal which is a function of the engine temperature. This signal is fed into
the electronic control centre and will produce the correction factor for the mixture strength as a function of the
engine temperature.
The transducer consist of a NTC thermistor can be contained in a brass threaded capsule «6A» or in a plastic one
«6B» - Fig.12-05 and Fig. 12-06.
In order to avoid damages to the transducer it must be mounted and blocked with a moderate torque.
The sealing washer at each disassembly.
NOTE: NTC means that the thermistor resistance decreases with the temperature increase.
Torque loading 0,01 kgm
