MSD Ignition Box Midget Car Oval Track Digital Capacitive Discharge 6214

MSD DIS-4 Plus digital ignitions improve the output of your late model distributorless ignition system (DIS). The capacitive discharge ignitions feature multi-channel capability, complemented with multiple sparks, two rev limiters, and a timing control. These DIS ignitions are engineered with the latest in digital science, including power MOSFET technology and efficient IGBT coil drivers. They're managed by a 15 MHz micro-controller for extremely fast compensations and decisions. In the end, this creates incredibly accurate spark delivery, rev limiting, and timing functions. Throttle response and mid-range pull are also improved, due to a series of powerful multiple sparks that last for 20 degrees of crankshaft rotation. There is a two-step rev limiter, which gives you one limit to set for holeshots and another for top-end performance. For engines using nitrous or extremely high cylinder pressures, you can also program a high-speed retard after the engine hits total timing. Both of these features are easy to adjust with the new built-in rotary dials. They also feature an ignition interrupt that will prevent the engine from starting by disabling the output to the coil, a retard feature that retards the timing at the top-end to prevent detonation, and an LED monitor that will alert you of a low supply of voltage or faulty input signals. Also, there is now a true step retard that can be activated through your nitrous solenoid wiring! The DIS-4 Plus ignitions are designed for 6 or 8-cylinder engines with three or four coil packs.
