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 the engine at idle, the ignition advance 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.

Check the efficiency of 7.5 A fuse No. 6 injection
load.
Check that the live control unit power supply 7.5A
fuse No. 10 works properly.
Check the efficiency of the injection load solenoid.
Check the resistance of the energising coil be-
tween pins 86 and 85: 40 to 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.
