Engine 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 Honda B-, D-, H-, and F-series 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. 

* Bolt-on systems available for Honda B-, D-, H-, and F-series engines 
* Very simple four-wire connection for easy installation (12V, ground, crank signal, and cam signal) 
* EPM manufactured from 6061 T-6 billet aluminum 
* Output signal amplitude and waveform stay constant at all RPM 
* 24-tooth crank, 1-tooth cam pattern per engine cycle for accurate timing and easy set up (Pattern available in cam/crank sensor wizard in AEMPro/Tuner) 
* Shock absorbing elastomer drive system eliminates potential for ignition timing deviation and protects the EPM from vibration
