The
DRL300 Rev Limiter single stage. The
DRL300 can clamp up to 4 of the Dyna blue (low impedance) coils. This means it
can be used on drag bikes, and many other applications including automotive HEI ignitions
as well as bikes equipped with Dyna S ignitions.

DRL300 cont.
~ In addition, the output stage has also added a separate kill input. This input
works separate of the rev limiter and can function even when the rev limiter has
no power. This will kill the spark whenever a 12V signal is applied to the
input.
Potential uses include shift kill to kill
ignitions during upshift, allowing for clutchless shifts. Instead of
having to cut jumper wires to get the box to work with a particular
application, and having only two choices, there are now 3 dip switches.
These dip switches allow not only for a very wide range of applications
(single fire thumpers to Harleys to inline 4s to 8 cylinders), but they
also allow for the rev range to be adjusted from the standard 6000-12000.
This means that new motorcycles with 12000+ rpm redlines can now be
handled, as can applications where the limit needs to be set below 6000.

The
DRL-400 Two-Stage Rev Limiter has
been specifically designed to maximize launch performance and over-rev
protection in drag racing. It allows precisely controlled launch RPM limit
to be set, while also guaranteeing against over-rev damage due to missed
shifts or drive train breakage.
DRL-400 Features:
-
Accurate launch limiting with 32 different settings
-
Smooth, non-destructive launch limiting
-
Adjustable high limit between 16 different settings
