AEM's Engine Position Module (EPM) Puck is a universal module that replaces an engine's distributor and allows for the use of coil-on-plug or wasted-park ignition systems on popular V8 and Honda B-, D-, H-, and F-series race 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.
