MSD engineers incorporated the favorite controls of the race proven programmable Digital-7 Ignition Control into an accessory for racers already using an MSD Ignition Control (MSD 6AL, SCI-L, 7AL-2 Series Ignitions). It is the only ignition accessory you'll ever need. The Multi-Function Ignition Controllers are loaded with easy to program adjustments. The Controller lets you adjust the timing of every cylinder, map a complete timing curve, pull timing out during the launch, set rev limits, shift points, start retard and much, much more. Two easy ways to program Controllers: 1) supplied PC software (Windows 95, 98 or NT); or 2) non-computer racers, there is a hand-held Programmer Monitor (P/N 121-7550). Use with MSD Ignition Control on 4, 6 or 8-cylinder engines. Plugs right into your computer. Comes with software, PC harness, vibration mounts, wiring and detailed instructions.
Connects to your standard MSD Ignition. Absolute control over your ignition timing. Control each cylinder's ignition timing. Different rpm shift points for each gear shift. Set an amount of retard to ramp back in during the launch. Three stages of retard for multiple nitrous systems.
