PerTronix Performance Products has introduced the Flame-Thrower digital rev limiter for use with any 4, 6 or 8 cylinder engine using points, OEM electronic (GM HEI, Ford, Chrysler) or aftermarket inductive type ignition systems including their very popular Ignitor® and Ignitor II points replacement systems.
This digitally controlled micro controller based unit provides much greater accuracy (+/-0.01%) than analog systems. Digital rotary switches permit easy setting and a resolution of 100 RPMs for more accurate rev control eliminating the need for chips and jumpers. Random spark stealing starts within one spark at the moment when the rev limit is exceeded reducing plug fouling common with repetitive stealing type limiters.
Flame-Thrower rev limiters come with special filters preventing false triggering from coil (-) voltage noise and a tachometer output compatible with modern tachometers. With reverse voltage protection, their limiter works well over a wide voltage range (6 to 18 volts).
A 4-wire hookup and the rev limiter’s small size (2.5”x 3.0” x 1.4”) make installation and fitment in many locations within the engine compartment easy.
