Main Features
  • Operates from points, reluctor, Hall Effect and optical triggers,
    or 5V signal from engine management computer
  • 5-15V negative earth operation
  • Selectable dwell period
  • Coil switches off whenever engine is not turning
  • Dwell extension with low battery voltage
  • Minimum spark duration of 1ms
  • Two points debounce periods
  • Special operation for poorly operating points
  • Anti-theft ignition disable switch option
  • Optional inverted trigger signal operation
  • This new electronic ignition system will not only will work with traditional points but will also happily function with any type of trigger signal – including those provided by factory and after-market reluctor, optical and Hall Effect distributors. It will even interface with an ECU ignition output trigger, making it a universal fit for all single coil cars, motorcycles and go-karts. It’s the ideal upgrade for an old points ignition system or it can be used to replace a defective factory ignition module – for as little as one-fifth of the price.

    This all-new design also compensates for lower battery voltages during cranking, features reduced coil heating, has adjustable intelligent dwell and incorporates a theft-prevention ignition disable.
