ELECTRICAL SYSTEM

Electronic ignition system

The ignition system is controlled by the ECU. The ignition is an integrated digi-
tal electronic ignition system with static timing and advance using intermittent
sequential phased electronic fuel injection. This ignition system is composed
of a crankshaft position (pick-up) sensor, an ECU, an ignition coil and an inta-
ke manifold pressure sensor. The ignition coil is fed by the battery through a
power relay and is controlled by the ECU. Ignition timing is accurately determi-
ned based on engine RPM and accelerator position. In addition to these key
parameters, inputs from the intake air temperature and pressure sensor and
from the coolant sensor are also used to control ignition timing.
