Cut-off
It refers to the supply cut-off function during deceleration.
Cylinder Balancing
Individual cylinder balancing contributes to increasing comfort and operability.
This function enables individual personalized fuel delivery control and delivery start for each cylinder, even differently between each
cylinder, to compensate for injector hydraulic toler ances.
The flow (rating feature) differences between the various injectors cannot be evaluated directly by the control unit. This information
is provided by the entry of the codes for every single injector, by means of the diagnosis instrument.
Synchronization search
The center can anyhow recognize the cylinder to inject fuel into even in the absence of a signal from the camshaft sensor.
If this occurs when the engine is already started, combustion sequence is already acquired, so the center continues with the
sequence it is already synchronized on; if it occurs with the engine stopped, the center onl y actuates one electro valve. Injection
occurs onside that cylinder within 2 shaft revs at the utmost so the center is only required to synchronize on the firing sequence
and start the engine.
This procedure must never be interrupted, by cutting the engine off from the battery cu tout or disconnec ting the latter before
10 seconds at least after engine cutout.
In this case, system operation is guaranteed until the fifth improper engine cutout, after which an error is stored in the breakdown
memory and the engine operates at lower performance at next start while the EDC warning light stays on.
Repeated procedure interruptions could in fact lead to center damage.
