AEM 30-3255 Engine Position Module User Manual
Page 2

The AEM Engine Position Module (EPM) replaces the Honda distributor and allows the
use of a coil on plug or wasted spark ignition system and can be used with any
aftermarket engine management system that recognizes the common 24 – 1 input for
crank and cam signal. The EPM provides precise engine position using dual zero
speed optical sensors. This offers the advantage of immediate signal generation when
the engine is cranked.
