The MCU controls engine air/fuel ratios, air injection and on some models, canister purge spark retard and idle speed. The MCU system is similar in many respects to the eec system's. The major difference is that the mca system does not completely control the ignition timing.....1985+ the MCU was only available on 5.8L cars with the optional police package or on canadian produced crown vic's........

hope that helps bro........
