WHAT IT DOES

AEM’s EPM module replaces an engine’s distributor and allows for the use of coil-on-plug or wasted-spark ignition systems on popular V8 engines. It eliminates rotor-phasing issues (“ignition drift”) common to high-performance distributed applications, enabling users to reliably increase power.

HOW IT WORKS

The EPM 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. AEM’s EPM Module is for use with programmable stand-alone engine management systems only.

EASY INSTALLATION!

The EPM saves installation time because it is not necessary to set up separate cam and crank input signals. Physical installation is simple via a four-wire connection (12V, ground, crank signal, and cam signal). It also eliminates air-gap issue concerns that are common with MAG sensors.

KEY FEATURES:

- Bolt on systems

- Eliminates need for separate cam and crank input signals

- Very simple four-wire connection for easy installation (12V, ground, crank signal, and cam signal)

- EPM housing is manufactured from 6061 T-6 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
