One spark after the Rev limit is exceeded, digital limiter controls rpm by randomly 'stealing sparks' reducing plug fouling common with other limiters. It operates on 6 to 18 volts with a 4-wire hookup for easy installation. Rotary switches permit easy setting and eliminate the need for chips or jumpers commonly found on other limiters.
This digital Rev limiter has two analog filters plus one filter that eliminates unwanted entry of voltage noise coming from the coil. Discounts are given for combining multiple items in one order. Not for use with CD ignition systems.
