Operation phases

Normal operation

When the engine is in standard thermic conditions, the 15M I.A.W. unit calculates the
phase, the injection time, the ignition advance, only by interpolation on the corresponding
stored presettings, according to rpm and throttle position.
The resulting amount of fuel is delivered to the two cylinders with two subsequent
injections.
The count of the initial delivery moment, for each cylinder, is made by means of a
presetting that depends on the number of revolutions.

Starting phase

When the ignition switch is in operation, the 15M I.A.W. unit feeds the fuel pump for few
time and detects the throttle angle and the temperature of the engine.
After starting the engine, the unit receives the revolution and phase signals, which allow it
to control the injection and the ignition.
To make the starting phase easy, an enrichment of the main quantity, upon the oil
temperature, is performed.
After the starting phase, the unit begins the check of the advance.

Acceleration operation

During acceleration, the system increases the delivered fuel quantity, in order to obtain the
best way of guide.
This condition is detected when the throttle angle variation reaches appreciable values, the
enrichment factor is determined upon the oil and air temperatures.
WARNING!
In order not to cause damages to the electronic ignition system, follow the
precautions hereunder:
in case of battery removal or refitting, be sure that the ignition switch is in
position OFF «
do not disconnect the battery with engine on;
be sure of the perfect efficiency of earth cables of electronic boxes;
do not electric weld on the vehicle;
do not use other electric devices for starting;
