Product Details

The mid 1980s was the beginning of the end for distributors in regard to new cars. The Buick Grand Nationals started using coil pack technology while many other GM vehicles were using dual tower coil packs sometimes known as Waste Spark systems. When Ford moved to the 4.6L Modular engine in the 96 Mustang, there were two coil packs with four towers each set up as a Waste Spark. Other common applications came from Mitsubishi and eventually Chrysler systems. MSDs DIS Ignition Controls are designed for engines with coil pack, waste spark ignition systems. The DIS-2 has two channels, to fire two coil packs, while the DIS-4 is capable of firing up to four coil packs (or even for individual coils). Each Control delivers full power Capacitive Discharge sparks from idle through racing rpm. Below 3,000 rpm there is a series of multiple sparks that last for up to 20ð to improve idle, starting and throttle response. The adjustable features of the DIS Ignitions have also been upgraded with rotary dials. These provide easier, and more precise adjustments of the overrev limiter and the holeshot rev limit. Also, there is now a step retard that can be wired directly to a nitrous system or switch for activation!
