19 OPERATING STAGES

N
ORMAL MODE
When the engine is thermally regulated, the I.A.W. 15 M
ECU calculates the stage, the injection time and the spark
advance exclusively by means of the interpolation on the
relative stored maps, according to the r.p.m. and the throttle
position.
The quantity of fuel determined in this way is supplied to
the two cylinders in two sequential deliveries.
The moment supply is started, for each cylinder, can be
determined by means of a map which depends on the
r.p.m..
S -
TART UP STAGE
The moment in which the starter switch is activated, the
ECU I.A.W. 15 M powers the fuel pump for several seconds
and acquires the throttle angle as well as the the engine
temperature.
Upon start-up, the ECU receives r.p.m. and timing signals
which allow it to then control injection and ignition.
To facilitate ignition, the basic dosage is enriched according
to the oil temperature.
After ignition, the ECU begins to control the spark advance.
