Manufacturer Applications
2 1. Engine speed.
2. Injection time (computed value between 1.5 and 3.5 ms at idle speed).
3. Digifant control unit voltage supply.
4. Intake air temperature
3 1. Engine speed.
2. Engine loading (idling).
3. Throttle valve angle (0 to 2.0% full load greater than 75%).
4. Duty cycle (off idling speed stabilisation valve (idling)).
4 1. Engine speed.
2. Engine load.
3. Road speed signal (stationary = 255, driving = 0).
4. Engine load operating state (see Table 11 for the relevance of the
figures in line 4).
5 1. Engine speed.
2. Duty cycle - Of activated charcoal filter solenoid valve -N80 (Valve fully
open = 100% valve closed =0%). This is closed when engine is idling
and so long as Lambda control is not active.
3. Consumption signal - On board computer calculation. The signal can
checked by observing it with the engine idling, then 'blipping' the throttle
to raise the engine speed and releasing immediately to bring the
overrun fuel cut-off function in. At idle the reading should indicate 1,
should then increase, drop to 0 then return to 1 again.
4. Operating condition (of Lambda control (see Table 9 for the relevance of
the figures in line 4)
