MSD Digital DIS-4 Plus Ignition Box

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 20° 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!
