The combined ignition/injection system is a high-efficiency induction system.
The control unit manages two significant parameters:
- Ignition advance
This is optimised at once according to the engine revs, engine load, temperature and ambient pressure.
With engine at idle speed, it is optimised to stabilise the speed at 1500 ± 100 rpm.
- Magnetisation time
The coil magnetisation time is controlled by the control unit. The power of the ignition is increased during
the engine start-up phase.
The injection system recognises the 4-stroke cycle so ignition is only commanded in the compression
phase.
Specific tooling
020331Y Digital multimeter
Check the efficiency of the 15A fuse «A».
Check the efficiency of the injection load remote
control: Check the resistance of the drive coil be-
tween pins 86 and 85: 40 ÷ 80 Ohm.
Apply a voltage of 12V to pins 86 and 85; make
sure that there is continuity between pins 30 and
87 of the remote control.
