MSD Ignition Soft Touch Rev Control

MSD Ignition Soft Touch Rev Control

Unlike many rev limiters which simply cut off the ignition spark, the MSD 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.


NOTE: Must only be used with an MSD 6T , 6TN or MSD 6 HVC Ignition and is adjustable for 4, 6 and 8-cylinder operation.
