MSD Digital GM high-energy modules with rev limiters allow you to adjust the rpm limit between 5,000 and 9,000 rpm. True high-performance modules built for HEI distributors, they produce 50 percent higher coil drive currents than the stock module. This saturates the coil faster, which gives you more spark energy at top speeds. The results are increased horsepower and rpm range, and improved starting. When used with MSD's HEI coil, these plug-in modules create a potent high-energy spark to 9,000 rpm. MSD GM HEI modules replace all 4-pin modules used in HEI distributors with a vacuum advance canister. They can be used with factory, aftermarket, or MSD HEI distributors.

These MSD 2-step module selectors let you choose from two different rpm limits that can be activated at different times. For example, you can use a lower-rpm module for staging and then automatically switch to a higher-rpm module after you release your trans-brake or line lock. They require the use of plug-in modules, which are available separately.

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.
