HYFIRE® VIIS SPORTSMAN

CD IGNITION SYSTEM

Part No. 667S

412 Cylinder

Notice: This product is legal for sale or use only on vehicles which may never be used on highways.

The HYFIRE® VIIS Sportsman CD Ignition Controls are not compatible with distributorless systems or
positive ground applications. The RPM Limiter in the HYFIRE® VIIS Sportsman CD Ignition Controls will not
work properly with odd-fire or semi-even fire V6 applications. The HYFIRE® VIIS Ignition System is not
designed for marine use.

GENERAL INFORMATION

INSTALLATION INSTRUCTIONS

The RPM limiter in the HYFIRE® VIIS Ignition System is not recommended as
an engine speed governor. The use of the RPM limiters is not recommended for
applications equipped with a catalytic converter. Similarly, forcing engine RPM
past the RPM limiter continuously for long sustained intervals can cause
problems resulting from fuel build up in the exhaust system that may adversely
affect the application.

Ignition Ballast Resistor / Loom Resistance Wire

The

HYFIRE® VIIS
of the factory ignition resistors or ignition ballast resistors in the wire from the
ignition switch. It is not necessary to install ignition ballast resistors as specified
by the instructions for the particular distributor.

Ignition Ignitions performance is not affected by the presence

Ignition Coils

The

HYFIRE® VIIS

PROMASTER® Coil Part No. 28880. Avoid using any other type of ignition coil.

Ignition System is designed to work with Mallory

Spark Plug Wires

YOU MUST USE suppression type (carbon core, spiral core) spark plug wire.
We recommend spiral core ignition wire, such as Mallory PRO SIDEWINDER
Ignition Wire. Suppression type spark plug wires prevent false triggering and the
possibility of premature ignition or accessory failures.

Spark Plug Gaps

For street applications, use your engine manufacturers specifications. For racing
applications, start with your engine manufacturers specifications, then experi­ment with the plug gap to achieve maximum performance.

Electric Welding

Disconnect the HYFIRE® VIIS Ignition System and unplug any distributor
harnesses (if possible) before any welding is done on the vehicle.

External RPM Limiters

Mallory RPM Limiter Part Nos. 641-4, 641-6, 641-8, 642, 643 and 644 WILL
NOT function with the HYFIRE

®

VII Ignition Systems.

Mallory PRO TACH® I, IV and IV

The tachometer and shift light will work with the HYFIRE® VII Ignition Systems.
However, the RPM limiter WILL NOT function with the HYFIRE® VII Ignition
Systems. Turn the LIMIT RPM knob slightly past 11,000 to prevent the RPM
limiter from interfering with the tachometers other functions.

®

DO NOT USE solid core (copper core; stainless steel core) spark plug wire with
any electronic ignition system or accessory. Solid core spark plug wire is a
source of ignition noise, which can cause false triggering and premature ignition
or accessory failure.

MOUNTING PROCEDURE

Step 1

Disconnect the battery () cable to cut power to the system.

Step 2

Select a convenient location to mount the HYFIRE® VIIS Ignition System. Keep
the unit away from hot engine components or extreme heat such as the exhaust
system and manifolds. Keep the unit away from moving devices, such as fans,
belts and linkages. The location must be dry. Moisture will damage components
inside the unit.

Step 3

Mounting to a flat surface with shock mounts

 Hold the unit in its mounting position and center punch the mounting pattern on

the mounting surface for drilling mounting holes. Drill mounting holes using a 9/
32" drill bit.

 Install the shock mounts into the bottom plate of the unit. Hold the unit in position

where it will be mounted.

 From the backside of the mounting surface, insert the washers and the 1/4-20

nylock nuts onto the shock mount studs. Tighten each nut until snug.

Step 1

Ensure that your vehicle is equipped with a ground cable between the engine
block and firewall (10 gauge or larger is required). Refer to Figure 1 while
performing the following steps.

 Connect the HEAVY RED wire to the 12-volt battery (+) post or battery (+)

terminal on the starter solenoid.
 Connect the HEAVY BLACK wire to engine or chassis ground.
 Connect wires between the COIL (+) and () terminals.
 Connect 12-volts from ignition switch to the +12V terminal.
 Connect the tach/RPM sensing wire and optional external RPM control to

sockets.

HYFIRE® VIIS TOP PANEL CONTROLS

Basic Operation

The top panel has a three-digit LED display, three LED indicators, and three
switches. The switches are used to set the mode and mode values, and the 3
separate LEDs indicate the mode. The four modes are listed below:

RPML LED
Main RPML (normally used as an engine protection RPM limit)

This value is valid as long as another RPM limit has not been selected. The range
is 1000 to 12800 RPM, in 100 RPM steps.

AUX LED
Aux RPML2 (normally used as a launching RPM control)

This value, if selected, overrides the main RPML. Range is 1000 to 12800 RPM,
in 100 RPM steps.

RET LED
HS RETARD1

This is a high-speed retard function which will retard the engine timing when
selected. The range is 1 to 15 degrees in .1 degree steps.

ALL MODE LEDs BLANK
CYLINDER NUMBER

This function allows you to select the engine cylinder number from 4 to 12 cyl­inders.

Setting Mode and Values

To adjust one of the modes, press the "MODE" switch until the proper mode LED
is lit (or none are lit, if you're selecting the cylinder mode ), then use the arrow
keys to increase or decrease the value. If you go past one end of the mode range,
the display will start over at the other end. For example, if you continue to
increase the RPML value past 12,800, the display will start over at 1000 RPM.

Start Retard

The HYFIRE

®

VIIS has a feature shared with the HYFIRE® VIIC: a built-in
automatic start retard. This automatically retards the engine timing below 500
RPM. The retard increases to 20 degrees at 100 RPM. Below 100 RPM, the
retard is fixed at 30 milliseconds, and above 500 RPM there is no automatic
retard.

Activation Plug

Although the activation plug has 8 contacts, only two are used on the

®

HYFIRE

VIIS: RPML2 for the Aux RPML, and HSRET 1 for the High-Speed

Retard function. If you add the optional HYFIRE® VIIC External Control Part No.
674, all other functions except the RPM switch relay contacts are available. The
plug has clamp-type terminals that will accept up to 14 gauge wire (stranded is
preferred, but solid will work). Insert the wire into the clamp, then tighten the
screw to hold the wire in place. The plug also has screws at each end to firmly
fasten to the socket on the HYFIRE

®

VIIS circuit board. Do not overtighten these
screws. Each RPML or Retard function requires 12 volts to activate. Typical
methods are clutch switch, trans brake switch, nitrous solenoid, or similar.

HYFIRE® VIIC AND VIIS

IGNITION SYSTEMS

Part One: Start Retard

The Mallory HYFIRE® VIIC AND VIIS Ignition Systems both have a built-in start retard feature. This retard is
20 degrees at 100 RPM, and decreases to 0 degrees at 500 RPM. This is a very useful feature which
eases the load on the starter motor when used with vehicles that have crank triggered ignition systems or
distributors with locked advances and 30 or more degrees of timing. However, there are applications
where the start retard is either not needed or not wanted. For example, motors with radical camshaft
profiles, large carbs and timing in the 15 to 25 degree BTDC range (Pro Mod motors, for example) may
experience lean-mixture backfiring during startup if the retard feature is active, especially if the tempera­ture is colder than usual.

Current production versions of the HYFIRE® VIIC AND VIIS have a yellow wire loop which comes out of the
back of the ignition box. Cutting this loop eliminates the start retard. Earlier versions of the ignition dont
have this feature, but the start retard can still be shut off. You must either send your ignition in to our service
department for modification, or, if you are attending an NHRA National event, you can bring your ignition to
our race support trailer and have it modified.

CUT YELLOW WIRE LOOP TO
ELIMINATE START RETARD

AFTER CUTTING YELLOW WIRE,
USE SHRINK TUBING TO INSULATE
EXPOSED ENDS

Part Two: Function Selection

The instructions for the HYFIRE® VIIC AND VIIS tell the user what each of the different functions do (such as
RPM limiters, timing retards, etc.). The instructions do not explain how to activate the functions.

To activate the functions of the HYFIRE® VIIC AND VIIS, you must apply 12 volts to the appropriate terminal.
Whether the user has a clutch pedal switch, a shifter button, or uses a timer, the auxiliary RPM limiters and the
timing retards need +12 volts to activate them.
