AEM 30-3251 Engine Position Module Chevy Small & Big Block Engines
AEM's Engine Position Module (EPM) replaces an engine's distributor and allows for the use of coil-on-plug or wasted-spark ignition systems on both Chevy Big and Small block 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.
Engine Position Module
Legal in California only for racing vehicles which may never be used upon a highway.
