INSTALLATION INSTRUCTIONS
FORM 1522TL
GENERAL INFORMATION
The features of the HYFIRE ® 6-A and HYFIRE ® 6-AL are the same,
with one exception: the HYFIRE ® 6-AL includes a single stage
RPM limiter. You can set various RPM limits using switches that
are accessible through the rectangular cut-out in the end bracket.
See page 12 of this instruction form for more information about
the rev limiting features of the HYFIRE
® 6-AL.
Battery
The HYFIRE
® 6A Series 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/hour 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
® 6A Ignition Control, we
recommend Mallory’s PROMASTER ® Coil P/N 29440 or 30440.
Mallory’s PROMASTER ® Coil P/N 29625 can also be used, as well as
most stock coils or aftermarket coils designed as stock replacements.
NOTE: Do not use Mallory’s PROMASTER ® Coil P/N 28880.
Tachometers
The yellow wire on the HYFIRE
® 6A 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 HYFIRE
® 6A 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
® 6A Ignition Control.
NOTE: Do not install the HYFIRE ® 6A Ignition Control in any
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
® 6A Ignition Control. This type of wire
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 ®
6A 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.
