FOR POINTS AND OEM IGNITION SYSTEMS
The Soft Touch #121-8728 is designed to be used on standard points ignition or inductive ignition systems. This means that the #121-8728 can be installed on engines wirh a GM HEI, Ford or Chrysler electronic ignition, any standard breaker points systems or even with and MSD-5 ignition. Unlike many rev limiters which simply cut off the ignition spark, the Soft Touch uses computer circuitry to drop one cylinder at a time and then fire that cylinder on the next cycle to prevent fuel from loading up the plugs. The result is very smooth rev limiting action that ''holds'' the engine at the selected rpm limit without backfires, extreme roughness or engine damage. The rpm limit is adjusted with plug-in modules and 6,000, 7,000 and 8,000 modules are supplied. Not for use with CD Ignitions. CARB legal in all 50-states via EO #D-40-29. FOR MSD 6T, 6TN or 6HVC IGNITION SYSTEMS
The same smooth operation and features as the #121-8728, but must be used on MSD 6T, 6TN or MSD 6HVC Ignition. CARB legal in all 50-states via EO #D-40-29.
