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.
GENERAL INFORMATION
Spark Plug Gaps
For street applications, use your engine manufacturers specifications. For racing
applications, start with your engine manufacturers specifications, then experi-
ment with the plug gap to achieve maximum performance.
Disconnect the HYFIRE

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

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.

I, IV and IV
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
Step 2
Disconnect the battery () cable to cut power to the system.
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.
Select a convenient location to mount the HYFIRE
