AEM Engine Position Module, Suit Honda B/D/H, (30-3255)
AEM's 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 a 12-tooth crank 1-tooth cam pattern.
Bolt-on systems available for Honda B-, D-, H-, and F-series race engines
Very simple four-wire connection for easy installation (12V, ground, crank signal, and cam signal)
Output signal amplitude and waveform stay constant at all RPM
Shock absorbing elastomer drive system eliminates the potential for ignition timing deviation and protects the EPM from vibration
12-tooth crank, 1-tooth cam pattern is available in cam/crank sensor wizard in AEMPro/AEMTuner/InfinityTuner)
