AEM's Engine Position Module (EPM) allows users to convert their distributed ignition system to coil-on-plug (COP) or wasted-spark. It replaces the factory distributor to allow for the use of COP or wasted spark when used with the necessary additional components. It provides precise engine position via dual zero-speed optical sensors that deliver immediate signal generation regardless of engine speed (24 and 1 timing signal). A shock absorbing elastomer drive system eliminates potential timing deviation from vibration and protects the EPM module.
The EPM adapts to any positive-drive, half-engine speed device (cam or distributor drive) and can be used with any engine management system that recognizes a 24 & 1 tooth pattern for crank and cam signals. Wiring is simplified through a 4-wire connection, which eases installation.
Replaces factory ignition distributor.
Bolt-on systems for popular Ford and Chevy V8 race engines.
Bolt-on system for popular Honda race engines.
Must be used with CDI module or Four-Channel Coil driver.
Easy EMS setup with timing pattern available in AEM tuner Wizard.
Simple weatherproof four-wire connection (12v, ground, crank signal & cam signal).
EPM manufactured from 6061 T-6 billet aluminum with elastomer drive system to protect against vibration and potential timing deviation from vibration.
