  • Quality Upgraded Timing Component
  • Operates On 6 To 18 Volts
  • Very Accurate Rev Limitation Will Protect Your Engine

This microcontroller based digital unit provides much greater accuracy than analog systems.  Rotary switches permit easy setting and eliminate the need for chips or jumpers commonly found on other limiters.  Settings in 100 RPM range increments provide for accurate rev control.  One spark after the rev limit is exceeded, the digital rev limiter controls RPM by randomly 'stealing sparks' reducing plug fouling common with other limiters.  This digital rev limiter has two analog filters plus one digital filter that eliminates unwanted entry of voltage noise coming from the coil.  It operates on 6 to 18 volts with a 4-wire hookup for easy installation.  Not for use with CD ignition systems.  Get the revs you want today!
