HYPERSPARK 2 EFI IGNITION BOX

556-154

WARNING! During installation, disconnect the battery cables. When disconnecting the battery, always remove

the NEGATIVE cable rst and install it last.

NOTE: Solid Core spark plug wires cannot be used with the HyperSpark 2 EFI Ignition Box.

NOTE: The HyperSpark 2 EFI Ignition Box cannot be used with distributorless ignition systems (DIS).

GENERAL INFORMATION:

BATTERY:

The HyperSpark 2 EFI Ignition box will operate on any negative ground, 12 volt electrical system with a distributor. It can

be used with 16 volt batteries and can withstand a momentary 24 volts in case of jump starts. The ignition will deliver full

output with a supply of 7 - 28 volts and will operate with a supply voltage as low as 7 volts.

COILS:

The HyperSpark 2 EFI Ignition can be used with most stock coils and aftermarket coils designed to replace the stock

coils. If you have any questions concerning coils, contact Technical Support at 866-464-6553.

SPARK PLUGS & WIRES:

Spark plug wires are very important to the operation of your ignition system. A good quality, helically wound, suppres-

sion-type wire and proper routing are required to get the best performance from your ignition, such as the super conduc-

tor MSD spark plug wires.

NOTE: Solid Core spark plug wires cannot be used with the HyperSpark 2 EFI Ignition.

Spark Plugs: Choosing the correct spark plug design and heat range is important when trying to get the best perfor-

mance possible. It is recommended to follow the engine builder or manufacturer’s specication for spark plugs. With

that, you can then experiment with the plug gap to obtain the best performance. The gap of the plugs can be opened in

0.005” increments, then tested until the best performance is achieved.

MISCELLANEOUS INFORMATION:

Welding: If you are welding on your vehicle, to avoid the chance of damage, always disconnect both Heavy Power ca-

bles of the HyperSpark 2 Ignition box from the Battery. You should also disconnect the tach ground wire.

MOUNTING:

The HyperSpark 2 EFI Ignition can be mounted in most positions, except directly upside down (if upside down, moisture

or water cannot escape). It can be mounted in the engine compartment as long as it is away from direct engine heat

sources. It is not recommended to mount the unit in an enclosed area, such as the glove box.

When you nd a suitable location to mount the unit, make sure the wires of the ignition reach their connections.

Hold the ignition in place and mark the location of the mounting holes. Use a 1/8” drill bit to drill the holes. Use the sup-

plied screws to mount the box.

WIRING: Wire Length: All of the wires of the ignition may be shortened as long as quality connectors are used or soldered in place. To lengthen the wires, use one size bigger gauge wire (10 gauge for the power leads and 16 gauge for the other wires) with the proper connections. Grounds: A poor ground connection can cause many frustrating problems. When a wire is specified to go to ground, it should be connected to the battery negative terminal, engine block or chassis.

White Wire Trigger: If you are using the White wire (points or electronic amplifier) of the HyperSpark 2 to trigger the ignition, follow these steps: 1. Make sure the ignition switch is in the OFF position. 2. Remove the coil wire from the distributor cap and position the terminal so it is approximately 1/2” from a good ground. 3. Disconnect the HyperSpark 2 White wire from the distributor points or the ignition amplifier. 4. Turn the ignition to the ON position. DO NOT CRANK THE ENGINE. 5.
