Product Information: 6EFI Universal EFI Ignition Box PN

6415

The 6EFI Universal EFI Ignition Box is a versatile electronic
ignition system designed for use with negative ground, 12-volt
electrical systems that have a distributor. It can also be used
with 16-volt batteries and can withstand momentary voltages of up
to 24 volts in case of jump starts. The ignition box operates with
a supply voltage range of 9 – 18 volts and can function with a
supply voltage as low as 7 volts.

Please note that the Universal EFI Ignition cannot be used with
distributorless ignition systems (DIS) and solid-core spark plug
wires.

If you have any questions regarding the compatibility of your
coils with the Universal EFI Ignition, please contact our Customer
Service Department at 915-855-7123.

Installation Instructions

1. Disconnect Battery

Before starting the installation process, disconnect the battery
cables. Always remove the negative cable first and install it
last.

2. Spark Plugs and Wires

Proper spark plug wires are crucial for optimal ignition system
performance. It is recommended to use high-quality, helically
wound, suppression-type wires like the super conductor MSD spark
plug wires.

Note: Do not use solid-core spark plug wires with the Universal
EFI Ignition.

When selecting spark plugs, refer to the engine builder or
manufacturer’s specifications for the correct design and heat
range. You can experiment with the plug gap by adjusting it in
0.005-inch increments to achieve the best performance.

3. Miscellaneous Information

Sealing: The Universal EFI Ignition comes with a thick conformal
coating of Humi-Seal, so there is no need to attempt to seal the
ignition. Rubber plugs are provided to protect the RPM dials.

Welding: If you need to perform welding on your vehicle, always
disconnect both heavy power cables of the ignition to prevent any
potential damage. It is also recommended to disconnect the tach
ground wire.

4. Cylinder Select

The Rev Limiter built into the ignition is initially programmed
for operation on an 8-cylinder engine. If you are installing the
ignition on a 4-cylinder or 6-cylinder engine, you need to select
the correct cylinder count. This can be done by cutting the
cylinder select wire loops on the side of the ignition according to
the instructions shown in Figure 1.

5. Grounds

A solid ground connection is essential for proper ignition
system operation. When a wire is specified to be grounded, it
should be connected to the battery negative terminal, engine block,
or chassis. Ensure that there is a ground strap between the engine
and the chassis. Always connect the ground wire securely to a
clean, paint-free metal surface.

The Ignition will deliver full output with a supply of 9 – 18 volts and will operate with a supply voltage as low as 7 volts.
COILS The Universal 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 our Customer Service Department at 915-855-7123.
TACHOMETERS The Universal EFI Ignition features a Tach Output wire that provides a trigger signal for tachometers, a shift light or other add-on rpm activated devices. The Tach Output produces a 12 volt square wave signal with a 24% duty cycle. Some vehicles with factory tachometers may require a Tach Adapter to operate with the ignition. For more information on Tachometers and MSD Tach Adapters, see the Tachometer Section on page 16. If your GM vehicle has an inline lter it may cause the tach to drop to zero on acceleration. If this occurs, bypass the lter.

INSTALLATION INSTRUCTIONS

SPARK PLUGS AND WIRES Spark plug wires are very important to the operation of your ignition system. A good quality, helically wound, suppression-type wire and proper routing are required to get the best performance from your ignition, such as the super conductor MSD spark plug wires.

Note: Solid Core spark plug wires cannot be used with the Universal EFI Ignition.

Spark Plugs: Choosing the correct spark plug design and heat range is important when trying to get the best performance 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 obtained.

MISCELLANEOUS INFORMATION Sealing: Do not attempt to seal the ignition. All of the circuits of the Universal EFI ignition receive a thick conformal coating of Humi-Seal. Rubber plugs are supplied to protect the rpm dials.

Welding: If you are welding on your vehicle, to avoid the chance of damage, always disconnect both Heavy Power cables of the ignition (You should also disconnect the tach ground wire).

MOUNTING The Universal 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 an 1/8″ drill bit to drill the holes. Use the supplied self tapping screws to mount the box.
CYLINDER SELECT The Rev Limiter that is built into the ignition is programmed for operation on a 8-cylinder engine. If you are installing one of these units on a 4 or 6cylinder even- re engine, the cylinder count must be selected. This is easily achieved through the cylinder select wire loops on the side of the ignition. To program the unit cut the loops as shown in Figure 1.

LED There is a diagnostic LED next to the rpm dials. The LED will blink with each trigger signal. It will appear On when the engine is running. If the input voltage drops below 9 volts it will ash at idle speed. For more codes, see page 17. 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 speci ed to go to ground, it should be connected to the battery negative terminal, engine block or chassis. There should always be a ground strap between the engine and the chassis. Always securely connect the ground wire to a clean, paint free metal surface.

WIRE FUNCTIONS

POWER LEADS These are the two heavy gauge wires (14 gauge) and are responsible for getting direct battery voltage to the Ignition.

HEAVY RED

This wire connects directly to the battery positive (+) terminal or to a positive battery junction or the positive side of the starter solenoid. Note: Never connect to the alternator.

HEAVY BLACK

This wire connects to a good ground, either at the battery negative (-) terminal or to the engine.

RED ORANGE BLACK

Connects to a switched 12 volt source. Such as the ignition key or switch.
Connects to the positive (+) terminal of the coil. This is the only wire that makes electrical contact with the coil positive terminal. Connects to the negative (-) terminal of the coil. This is the only wire that makes electrical contact with the coil negative terminal.

GRAY TRIGGER
WIRES

Tach output wire. Connect to the tachometer or other rpm device. There are two circuits that can be used to trigger the Universal EFI Ignition; a Points circuit (White wire) and a Magnetic Pickup circuit (Violet and Green wires). The two circuits will never be used together.

WHITE

This wire is used to connect to the points or electronic ignition ampli er output .

VIOLET AND GREEN
(Magnetic Pickup Connector)

These wires are routed together in one harness to form the Magnetic Pickup connector. The connector plugs directly into an MSD Distributor. It will also connect to factory magnetic pickups or other aftermarket pickups. The Violet wire is positive (+) and the Green is negative (-). When these wires are used, the White wire is not.

The chart in Figure 2 shows the polarity of other common magnetic pickups.

Ballast Resistor: If your vehicle has a ballast resistor in line with the coil wiring, it is recommended to bypass it.

ROUTING WIRES The spark plug wires should be routed away from direct heat sources such as exhaust manifolds and headers and any sharp edges. The trigger wires should be routed separate from the other wires and spark plug wires. It is best if they are routed along a ground plane such as the block or rewall which creates an electrical shield. The magnetic pickup wires should always be routed separately and should be twisted together to help reduce extraneous interference.

Figure 2 Common Mag Pickup Wires.

WARNING: The Universal EFI Ignition is a capacitive discharge ignition. High voltage is present
at the coil primary terminals. Do not touch the coil or connect test equipment to the terminals.

INSTALLATION INSTRUCTIONS

REV LIMITER The Universal EFI Ignition features an adjustable rev limiter. This feature will protect your engine from over rev damge in the event of driveline failure or a missed gear. The rev limit is adjustable from 2,000 – 9,900 rpm in 100 rpm increments (Figure 3).

PRESTART CHECK LIST

· The only wires connected to the coil terminals are the Universal EFI

Ignition Orange to coil positive and Black to coil negative.

· The small Red wire of the CDI is connected to a switched 12 volt source.

· If running a 4 or 6-cylinder engine the cylinder select must be modi ed.

· The power leads are connected directly to the battery positive and

negative terminals. · The battery is connected and fully charged if not using an alternator. · The engine is equipped with at least one ground strap to the chassis.

Figure 3 Adjusting the Rev Limiter.

TIMING CONTROL

Some EFI systems have the ability to control the engine’s ignition timing, however, an adjustable rotor

is required to use this feature. For initial startup, it is recommended to bypass the timing control

features. This will allow you to start the engine and tune the EFI to your engine.

MSD recommends that those who wish to use the timing control feature rst get the engine to run

without timing control. Splitting the timing control into a secondary process will add very little time to

the total install, but could signi cantly help with trouble shooting, should it be needed.

The following are a list of items that are required to use the timing features of the some EFI

systems: Y An MSD Ignition control such as a 6EFI Universal EFI, 6A or 6AL Ignition Y The distributor must be locked-out Y An adjustable rotor is required to achieve accurate rotor phasing. For standard GM size MSD

distributors, use rotor PN 84211. For larger, Ford style MSD distributors it is recommended to t the

distributor with a smaller cap (PN 8433) and the PN 84211 rotor. If the larger cap must be used, try

rotor PN 8421.

Y It is recommended but not required to us an MSD Pro Billet Distributor with a 2-pin mag pickup connector.

Y The balancer must be degreed, or use MSD Timing Tape, PN 8985

Y A timing light will be required.

PREPARATION FOR TIMING CONTROL

Before removing the distributor, bring the number one cylinder to approximately 15° BTDC on the

compression stroke. 1. Remove the distributor cap and note the position of the

rotor. You will be removing the distributor to lock it out, this

will be your reference position for the number one cylinder.

2. Remove the distributor clamp and pull the distributor out

TROUBLESHOOTING
Every Universal EFI Ignition undergoes numerous quality control checks including a four hour burn-in test. If you experience a problem with your ignition, our research has shown that the majority of problems are due to improper installation or poor connections. The Troubleshooting section has several checks and tests you can perform to ensure proper installation and operation of the Universal EFI Ignition. If you have any questions, call our Customer Support Department at 915-855-7123, 8 – 5 mountain time.

TACH/FUEL ADAPTERS If your tachometer does not operate correctly or if you experience a no-run situation with your foreign vehicle you probably need a Tach Adapter from MSD Ignition. The chart below lists common tachometers and if an Adapter is necessary.

Note: On the list above, the trigger wire on tachometers that are marked NONE may be connected to the Tach Output wire on the Universal EFI Ignition. INOPERATIVE TACHOMETERS If your tachometer fails to operate with the CDI installed you may need a Tach Adapter from MSD Ignition. Before getting an Adapter, try connecting your tachometer trigger wire to the Gray Wire. This output produces a 12 volt, square wave. If the tach still does not operate, you will need a Tach Adapter. There are two Tach Adapters: PN 8920: If you are using the Magnetic Pickup connector (Green and Violet wires) to trigger the CDI,
you will need the PN 8920. PN 8910: If your tachometer was triggered from the coil negative terminal (voltage trigger) and you are
using the White wire to trigger the cdi you will need the PN 8910.
ENGINE RUN-ON If your engine continues to run even when the ignition is turned Off you are experiencing engine RunOn. This usually only occurs on older vehicles with an external voltage regulator. Because the CDI receives power directly from the battery, it does not require much current to keep the unit energized. If you are experiencing Run-On, it is due to a small amount of voltage going through the charging lamp indicator and feeding the small Red wire even if the key is turned off. Early Ford and GM: To solve the Run-On problem, a Diode is supplied in the parts bag. By installing this Diode in- line of the wire that goes to the Charging indicator, the voltage is kept from entering the CDI. Figure 7 shows the proper installation for early Ford and GM vehicles. Note: Diodes are used to allow voltage to ow only one way. Make sure the Diode is installed facing
the proper direction (as shown in Figure 7). M S D · WWW.MSDPERFORMANCE.COM · 915-857-5200 · FAX 915-857-3344

INSTALLATION INSTRUCTIONS

19

Ford: Install the Diode in-line to the wire going to the #1 terminal. GM: Install the Diode in-line to the wire going to terminal #4. GM 1973 – 1983 with Delcotron Alternators GM Delcotron Alternators use an internal voltage regulator. Install the Diode in-line on the smallest wire exiting the alternator (Figure 7). It is usually a Brown wire.

Figure 7 Installing the Diode to x Run-on LED The LED on the side of the Universal EFI ignition monitors several operating conditions of the ignition. If the LED indicates that there is a problem with the ignition system, follow the steps through the Troubleshooting section. The LED will appear to be on steady at above idle speeds when everything is functioning properly. · When 12 volts are applied to the small Red wire, the LED will turn on to indicate power. · When cranking or running, the LED will blink for each trigger signal. · If the input voltage drops below 9 volts it will ash at idle speed. · Code 2 will ash for low battery voltage. · Code 3 will ash for converter off (ignition problem)
MISSES AND INTERMITTENT PROBLEMS Experience at the races has shown that if your engine is experiencing a miss or hesitation at higher rpm, it is usually not directly ignition. Most probable causes include a coil or plug wire failure, arcing from the cap or boot plug to ground or spark ionization inside the cap. Several items to inspect are: · Always inspect the plug wires at the cap and at the plug for a tight connection and visually inspect for
cuts, abrasions or burns. · Inspect the Primary Coil Wire connections. Because the Universal EFI ignition is a Capacitive
Discharge ignition and it receives a direct 12 volt source from the battery, there will not be any voltage at the Coil Positive (+) terminal even with the key turned On. During cranking or while the engine is running, very high voltage will be present and no test equipment should be connected. WARNING: Do not touch the coil terminals during cranking or while the engine is running. · Make sure that the battery is fully charged and the connections are clean and tight. If you are not running an alternator this is an imperative check. If the battery voltage falls below 10 volts during a race, the CDI output voltage will drop. · Is the engine running lean? Inspect the spark plugs and complete fuel system. · Inspect all wiring connections for corrosion or damage. Remember to always use proper connections followed by soldering and seal the connections completely. If everything checks positive, use the following procedure to test the ignition for spark. MSD also offers Ignition Testers (PN 8998 or 89981). This tool allows you to check your complete ignition system while it is in the car as well as the operation of rpm limits, activated switches and shift lights.

INSTALLATION INSTRUCTIONS

CHECKING FOR SPARK

If triggering the ignition with the White wire:

1 Make sure the ignition switch is in the “Off” position. 2. Remove the coil wire from the distributor cap and set the
terminal approximately 1/2″ from ground. 3. Disconnect the White wire from the distributor’s points or
ignition ampli er. 4. Turn the ignition to the On position. Do not crank the
engine. 5. Tap the White wire to ground several times. Each time you
pull the wire from ground, a spark should jump from the coil wire to ground (the LED should also blink). If spark is present, the ignition is working properly. If there is no spark skip to step 6.

Figure 8 Checking for Spark with the White Wire.

If triggering with the Magnetic Pickup:

1. Make sure the ignition switch is in the “Off” position.

2. Remove the coil wire from the distributor cap and set the

terminal approximately 1/2″ from ground.

3. Disconnect the magnetic pickup wires from the distributor.

4. Turn the ignition to the On position. Do n ot crank the engine.

5. With a small jumper wire, short the magnetic pickup Green and

Violet wires together several times. Each time you break this

short, a spark should jump from the coil wire to ground (the LED should also blink). If spark is present, the ignition is working properly. If there is no spark skip to step 6.

Figure 9 Checking for Spark with Magnetic Pickup.

6. If there is no spark:

A. Inspect all of the wiring. B. Substitute another coil and repeat the test. If there is now spark, the coil is at fault. C. If there is still no spark, check to make sure there is 12 volts on the small Red wire from the
Universal EFI Ignition when the key is in the On position. If 12 volts is not present, nd another switched 12 volt source and repeat the test. D. If, after following the test procedures and inspecting all of the wiring, there is still no spark, the Universal EFI Ignition is in need of repair. See the Warranty and Service section for information.
