MSD
DIS-2 HO, PN
62113 (2-Channel
Ignition)
MSD DIS-4 HO, PN
62153 (4-Channel
Ignition)
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 engines 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 engines
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 ignitions 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 ignitions 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.
