Fuel pump
The two fuel pumps are supplied by a relay controlled by LIE control unit. For safety reasons the pump relevant to
cylinder bank 1-6 is controlled by LIE control unit of cylinder bank 7-12 and vice versa. They are roller type positive displacement pumps with permanent magnet energizing.

with the pump at a standstill. This valve is especially important since by holding the system pressure it prevents fuel vapor from forming (vapor-lock) that causes damage when starting up with a warm engine.

Due to security reasons concerning the presence of throttle bodies the fuel pumps and injectors of cylinder bank 1-6
are supplied by relays controlled by LIE 7- 12 control unit and vice versa.
The pumps are stopped:
• If the engine speed drops under 350 rpm approx.;
• After a certain time (about 3 seconds) with the key to MAR position without starting up (timed enable);
Self-learning strategy
Self-learning only affects the optimum air percentage for the idle speed (0 to 60 seconds). The strength is kept constant with the target strength (value requested by the system under that particular operation condition).
The range of operation of the pre-catalytic oxygen sensor (linear) is 0.8 to 1.20.
If the value is below 1.00, the system is RICH; otherwise, the system is POOR.
The self-learning values of the linear oxygen sensors are always saved in the control unit during normal
operation.

The ignition control mainly consists of determining the spark advance required according to the engine operating
conditions and its actuation by the piloting of the power transistor incorporated in the power module inside the engine control unit.
The spark advance calculated on the basis of the engine load and speed is then corrected according to different engine operating conditions.
Each coil primary is supplied by the battery voltage through a relay which, in its turn is controlled by the engine
control unit: The connection to round takes place through the power transistor.
The engine control unit, after a cylinder TDC signal, sends a signal, with a certain delay, to the relevant power
module, that starts at that moment (conduction start moment) to send current to the coil primary circuit to bring the
value to about 6 Amperes (saturation current).
Obviously this moment varies in angle in relation to the bursting TDC of each cylinder since the dwell needed to
saturate the current in the coil primary circuit is constant, whereas the time required by the engine to make two revolutions (cycle) reduces as the rotation speed increases. 7 K H H Q J L Q H F R Q W U R O X Q L W V L J Q D O U H P D L Q V X Q W L O W K H P R P H Q W R I W K H G H V L U H G V S D U N D G Y D Q F H R Q W K H V S H F L ¿ F F \ O L Q G H U
The moment the control unit removes the signal from the power module, the current in the coil primary circuit is cut
off. This, by induction, generates a sudden rise in voltage on the secondary circuit that is discharged to ground, generating a spark on the ignition spark plug.
