INJECTION ELECTRONIC CONTROL UNIT
The injection electronic control unit processes the signals coming from the various sensors through the
application of software algorhythms and controls the operation of the actuators (in particular the injectors
and pressure regulator) to ensure the best possible operation of the engine.
The control unit is the flash E.P.R.O.M. type which can be reprogrammed from the outside without ad-
justing the hardware.
The injection control unit includes an absolute pressure sensor and is connected to the wiring by means of
a 134 pin connector.
