MSD DIS
Ignition Controls are
designed for engines with
coil pack, waste spark
ignition systems. The DIS-4
has four channels, to fire up
to four coil packs (or even
four individual coils). Each
Control delivers full power
Capacitive Discharge sparks
from idle through racing rpm.
Below 3,000 rpm there is a
series of multiple sparks
that last for up to 20
degrees of crankshaft
rotation to improve idle,
starting and throttle
response. The adjustable
features of the DIS Ignitions
have also been upgraded with
rotary dials. These provide
easier, and more precise
adjustments of the over rev
limiter and the holeshot rev
limit. Also, there is now a
step retard that can be wired
directly to a nitrous system
or switch for activation!
