map-controlled ignition

A microprocessor-controlled ignition system with electronic ignition timing by means of an ignition map stored in the control unit memory. The engine speed is sensed by Hall generators at the distributor or magnetic pick-ups on the crankshaft, the load signal being given by pressure sensors which measure the air mass or air per unit of time
