The Soft Touch Rev Control, PN 8728, is designed to be used on standard points ignition or inductive ignition systems. This means that the PN 8728 can be installed on engines with a GM HEI Ignition, Ford or Chrysler electronic ignition, any standard breaker points systems or even with an MSD 5 or Blaster Ignition (non-CD ignitions). The Soft Touch Rev Control is adjusted with plug-in modules and is supplied with 6,000, 7,000 and 8,000 rpm modules. When the engine reaches your set rpm, the Soft Touch circuitry kicks in and drops the spark to certain cylinders. This limiter produces very accurate and smooth, backfire-free rev limits.Can be used on 4, 6 or 8-cylinder engines with inductive ignitions. No MSD Ignition Control required.
There are two ways to limit your rpms. The rough way simply cuts off ignition spark, which can cause backfiring, extreme engine roughness, and possible engine damage. The gentle way is with these MSD Soft Touch rev controllers. They use sophisticated computer circuitry to drop spark one cylinder at a time, until your engine is at or below its maximum rpm. Those cylinders are then fired on the next cycle, to prevent them from loading up with fuel. The result is smooth rev limiting action without all the rough stuff. There are two versions of the Soft Touch rev controllers--one for MSD's 6T, 6TN, 6HVC ignitions, and one for OEM electronic and points ignitions. Both come with 6,000, 7,000, and 8,000 rpm plug-in modules, and can be used with other modules or MSD's RPM module selector.
