MSD

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 (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, more precise adjustments of the over-rev 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!
