DISTRIBUTORLESS Ignition

Distributorless ignition system is controlled by ECM. ECM receives signals from mass air flow sensor, engine coolant temperature sensor, crankshaft position sensor, camshaft position sensor, knock sensor, throttle position sensor and park/neutral switch to operate engine at optimum efficiency. Ignition timing is also determined by ECM which immediately transmits a primary current OFF signal to the ignitor to control ignition timing. Ignition timing is fixed at 10 degrees during a starting condition.
