Mallory HYFIRE 6AL2 Installation Instructions Manual

ELECTRONIC IGNITION CONTROL
PARTS INCLUDED:
1 HYFIRE ® 6AL2 Ignition Control
4 #10 Sheet Metal Screws
2 Wire Ties
2 Ring Terminals, Insulated
1 1-amp/100 volt Diode
2 1/4" Tab Terminals
GENERAL INFORMATION
The HYFIRE ® 6AL2 includes a two stage RPM limiter. You can set
various RPM limits using the switches that are located in the end
bracket. See Figure 1 of this instruction form for more information
about the rev limiting features.
Battery
The HYFIRE ® 6AL2 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 HYFIRE
we recommend a Mallory PROMASTER
or 30441 Mallory PROMASTER
coil part numbers 29625, 30625 or 30626 can also be used. You
may also use most stock coils or aftermarket coils designed as
stock replacements.
NOTE: Do not use Mallory's PROMASTER
Tachometers
The yellow wire on the HYFIRE
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 HYFIRE ® 6AL2 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 4.

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. Use the chart at right as a starting
point. 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
HYFIRE ® 6AL2 Ignition Control.
NOTE: Do not install the HYFIRE
vehicle that is originally equipped with a CD ignition control.
Spark Plugs and Wires
High quality, spiral wound wire and proper routing are essential to
the operation of the HYFIRE
provides a good path for the spark to follow while minimizing
electromagnetic interference (EMI).
NOTE: Do not use solid core spark plug wires with the HYFIRE
6AL2 Ignition Control.
Routing
Wires should be routed away from sharp edges, moving objects,
and heat sources. Wires that are next to each other in the engine's
firing order should be separated. For example, in a Chevy V8 with a
firing order of 1-8-4-3-6-5-7-2, the #5 and #7 cylinders are
positioned next to each other on the engine as well as in the firing
order. Voltage from the #5 wire could jump to the #7 wire. This
could cause detonation and engine damage.
For added protection against cross-fire, Mallory offers PRO SHIELD
insulated sleeving. Pro Shield is a glass woven, silicone coated
protective sleeve that slides over your plug wires. It also helps
reduce damage from heat and sharp objects.
