Description: Now late model engines with distributorless ignition systems (DIS) can take advantage of MSD performance with these Digital DIS-4 ignitions. 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 e 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 built-in dip switches. 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. The DIS-4 ignitions are designed for 6 or 8-cylinder engines with three or four coil packs.(minimize)
