EZL Ignition Control Unit

EZL ignition control unit stores ignition specifications for various engine operating conditions. EZL unit triggers ignition coil based on input data from intake manifold vacuum, coolant temperature, crankshaft position indicator (TD unit) and throttle valve position.

Data is exchanged between CIS-E control unit and EZL ignition control computer unit to optimize emissions. Computer units compare information such as intake manifold vacuum for altitude corrections and for engine load requirements, intake air temperature, coolant temperature and malfunction indications.
