INSTALLATION INSTRUCTIONS
NITROUS 6
ELECTRONIC IGNITION CONTROL
PART NO 6865M
GENERAL INFORMATION
The NITROUS 6 includes a single stage
RPM limiter and a single stage ignition
retard. You can set various settings using
the switches that are located in the end
bracket. See Figure 1 of this instruction form
for more information about the rev limiting
and ignition retard features.
Battery
The NITROUS 6 Ignition Control operates on
any negative ground, 12 volt electrical
system with a distributor. It will also work
with 16 volt batteries and can withstand a
momentary spike of 24 volts in case of jump
starts. This system delivers full voltage with
a supply of 10-18 volts, and operates with a
supply voltage as low as 8 volts.
If your application does not use an alternator,
allow at least 15 amp/hours for every half
hour of operation. If you crank the engine
with the same battery or other accessories,
such as an electric fuel or water pump,
increase the amp/hour rating.
Coils
For optimum performance with your
NITROUS 6 Ignition Control, we recommend
a Mallory PROMASTER® Coil P/N 29440 or
30440 or 30441 Mallory PROMASTER® E.
For continuous high rpm use, coil part
numbers 29625, 30625 or 30626 can also be
used. You may also use most stock coils
designed for use with OEM electronic ignitions.
NOTE: Do not use Mallory’s PROMASTER®
Coil P/N 28880.
Tachometers
The yellow wire on the NITROUS 6 Ignition
Control provides a trigger signal for
tachometers, shift lights, or other add-on
RPM activated devices. This wire produces
a 12 volts square wave signal with a 20%
duty cycle.
Some vehicles with factory tachometers may
require a tach adapter to work with the
NITROUS 6 Ignition Control. If your GM
vehicle uses an inline filter, it may cause the
tach to drop to zero on acceleration. If this
occurs, bypass the filter. For more information
on tachometers, see page 5.
Spark Plugs
Using the correct spark plug and heat range
is important for optimum performance.
Because there are so many
variables to consider, we suggest starting
with your engine manufacturer’s spark plug
recommendation. From there, you can
experiment with small changes in plug gap
and heat range to obtain the best performance
from your engine. We also recommend
non-resistor spark plugs.
Foreign Vehicles
Because of modern fuel injection systems,
some foreign vehicles may require a
tachometer/fuel injection adapter to work
with the NITROUS 6 Ignition Control.
NOTE: Do not install the NITROUS 6 Ignition
Control in any vehicle that is originally
equipped with a CD ignition control.
