Distributorless Ignitions: For Late model engines with distributorless ignition systems (DIS), we offer a variety of DIS Ignition's from street to racing units.
|
   
MSD DIS-2 HO (2-Channel Ignition) , PN 62113
MSD DIS-4 HO (4-Channel Ignition) , PN 62153
|
The DIS Ignitions all deliver a stout, CD spark that is capable of burning
the majority of air/fuel mixtures. There are of course exceptions, such
as full bred race engines running high boost pressures from turbos,
blowers or nitrous. To answer these needs, we offer a Higher Output
version of the DIS Ignition Controls.
The DIS Plus HO Ignitions produce an incredible 170 millijoules
of spark energy with 470 primary volts. This increased output will
light up fuel mixtures even under extreme cylinder pressures.
The DIS-HO boxes are not CARB approved and are designed
for drag racing applications only.
Soft Touch REV Control
The DIS-2 and DIS-4 both feature an adjustable built-in Soft Touch Rev Control to protect the engine from overrev damage caused by missed shifts or broken driveline components. This feature produces a smooth rev-limiting action by randomly dropping one cylinder at a time and then refiring that cylinder on the next firing cycle. This feature is easily adjusted with simple program switches mounted on the side of the unit.
Two Step Module Selector
The Two Step function of the MSD Digital DIS Ignition allows you to activate a low rpm limit while staging and waiting for the light to turn green. This popular feature gives you a distinct advantage over your competition by permitting you to control your engine's rpm precisely before every launch. With a fixed rpm limit at the starting line, each launch will be consistent and quick! The rpm limit is easy to adjust in 250 rpm increments with switches built into the side of the housing.
Programmable Timing Control
Precise timing control is essential to producing maximum engine power. With the addition of nitrous, turbos or supercharger systems, timing becomes even more critical. To get the most out of your engine, the ignition must be able to compensate for these extreme changes in cylinder pressure throughout the engine's entire rpm range. During low speed operation, the MSD DIS Ignitions use the factory ignition to control basic timing functions. Once maximum timing is achieved, the DIS-2 and DIS-4 can be programmed to retard the timing at a specific rate and rpm point to prevent engine damage due to detonation caused by excessive timing.
LED Monitor
 A built-in LED monitor is a useful tool to determine the status of the charging and ignition systems. When the battery voltage drops below 8 volts, the LED will begin flashing at a rate of two times per second, letting you know that the charging system is not operating properly or that the battery has failed. Also, if any of the ignition's channels lose their trigger input, the LED will flash at a rate of one flash per second.
Ignition Interupt
To prevent accidental or unauthorized starting of the vehicle, the MSD DIS Ignition systems feature a driver activated ignition interrupt feature that can be used as an anti-theft device. When activated, this feature will prevent the engine from starting by disabling the ignition's voltage output to the coil.
EMI Noise Protection
As with all MSD Ignition products, additional protection from Electro Magnetic Interference (EMI) has been added to the design of the DIS. Special circuitry filters out unwanted noise that commonly causes other aftermarket ignition systems to false trigger, operate intermittently and even fail.
