The MSD Module Selectors
allow you to choose two or
three different rpm limits
that can be activated at
different times. With this
ability, the possibilities
are endless. As an example,
we'll use a drag car with a
Three Step Module Selector
plugged into the rpm socket
of a 7AL-2 Ignition. The
different rpm modules are
activated when 12 volts are
applied to a corresponding
wire. By connecting one wire
to the line-lock circuit, one
module will be activated
during the burnout. This
helps keep tire temperatures
consistent. When the
line-lock button is released,
the limit turns off. When
you're on the starting line,
you can activate the second
limit through the clutch or
trans switch. This provides a
steady and consistent rpm for
firm holeshots every time.
When no modules are selected,
the remaining high limit is
active to protect the engine
in the event of driveline
failure. The Two Ste p works
th two different limits. The
Module Selectors can also be
used with an MSD Timing
Control. By plugging the
Selector into a retard module
socket, you can activate
different retard amounts at
select times. This is a great
feature for engines being
upgraded to a multi-stage
nitrous system. With the
addition of an RPM Activated
Switch, you can use the Two
Step to activate a shift
light at different rpm. The
Module Selectors must be used
with an MSD Soft Touch Rev
Control or a Timing
Controller with a high-speed
retard module.
No rpm or
retard modules are supplied.
