Micro Controller

Provides greater accuracy than analog systems. digital rotary switches permit easy setting and a resolution of 100 RPMs for accurate rev control eliminating the need for chips and jumpers. Random spark stealing starts at the monent when the rev limit is exceeded reducing plug fouling common with repetitive stealing type limiters. Special filters prevent false triggering from from coil voltage noise and a tach output compatible with modern tachometers. Simple 4-wire hook-up. Works on 4-6-8 cylinder. 50-State Legal. Measures 2.5'' x 3'' x 1.4''.
