When you need to limit your RPM, there’s only one way to avoid backfiring, severe engine roughness and eventual engine failure –an MSD Soft Touch Rev Control. A surefire way to achieve smooth, accurate rev limits, it can be used with 4-, 6- and 8-cylinder engines with inductive ignitions or installed on engines with a GM HEI Ignition, Ford or Chrysler electronic ignition, any standard breaker points systems and even with an MSD 5 or Blaster Ignition (non-CD ignitions).
Sophisticated circuitry kicks in once your engine reaches the set RPM and drops the spark one cylinder at a time until you drop below the set maximum RPM. It adjusts easily with included 6,000, 7,000 and 8,000 RPM plug-in modules. Your MSD Soft Touch Rev Control is backed by a limited warranty.
