Engine specific position module (epm)

AEM's Engine Position Module (EPM) replaces an engine's distributor and allows for the use of coil-on-plug or wasted-park ignition systems on Ford's 351/Windsor Block Engines. It provides precise engine position using dual zero-speed optical sensors, which offers the advantage of immediate signal generation regardless of engine speed. The EPM easily adapts to any positive-drive, half-engine speed device such as a cam or distributor drive, and can be used with any aftermarket engine management system that recognizes the common 24 & 1 pattern for crank and cam signals.

Legal in California only for racing vehicles which may never be used upon a highway.
