| FORM 1460 (REV. C) 5/00 INSTALLATION INSTRUCTIONS (R) HYFIRE(R) VIIC PRO CD IGNITION 667C SYSTEM Part No. 4-12 Cylinder 6 Cylinder Odd-Fire Notice: This product is legal to sell, distribute or install on vehicles in California. Executive Order D-70-6. The HYFIRE(R) VII Pro CD Ignition Controls are not compatible with distributorless systems or positive ground applications. The HYFIRE(R) VII Ignition System is not designed for marine use. GENERAL INFORMATION The RPM limiter in the HYFIRE(R) VIIC 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. 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 and closely monitor various gaps to achieve maximum performance. Disconnect the HYFIRE(R) VIIC Ignition System and unplug any distributor harThe HYFIRE(R) VIIC Ignition Ignition's performance is not affected by the pres- nesses (if possible) before any welding is done on the vehicle. ence of the factory ignition resistors or ignition ballast resistors in the wire from the ignition switch.

Turn the LIMIT RPM knob slightly past 11,000 to prevent YOU MUST USE suppression type (carbon core, spiral core) spark plug wire. the RPM limiter from interfering with the tachometer's other functions. We recommend spiral core ignition wire, such as Mallory PRO SIDEWINDER(R) Ignition Wire. Suppression type spark plug wires prevent false triggering and the possibility of premature ignition or accessory failures. Ignition Ballast Resistor / Loom Resistance Wire Electric Welding Ignition Coils 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 one cause of electro-magnetic interference (EMI; ignition noise). EMI is one cause of false triggering (preignition; spark scatter) and premature ignition or accessory failures. MOUNTING PROCEDURE Step 1 Disconnect the battery (-) cable to cut power to the system.

YOU MUST USE Mallory PROMASTER(R) Coil Part No. 28880 with this ignition system 3 USING THE HYFIRE VIIC FEATURES Your Mallory HYFIRE(R) 667C has a number of built-in features that make it RPM Limiters: easier to use. This instruction addition tells how to use these built-in features. The HYFIRE(R) 667C has three built-in RPM limiters. Each one has a range of 1000 to 12,800 RPM in 50 RPM steps. On the main display, there is a deciFirst, take a look at the top of the main unit. You'll see that there is an 8-pin mal point on the mode digit. When that decimal point is lit up, the RPM limit connector beneath the surface, Supplied in the plastic bag that came with is increased by 50 RPM. your Hyfire is an 8-pin plug that fits this connector. It has screw clamp terminals that accept up to 14 gauge wire. For best results, use stranded , insu- RPM1 (Mode 1) This is the RPM limit that is always active if you haven't selected any other RPM limit. lated copper wire, rather than solid wire. The plug is made so that it will only fit one way, and has hold down screws at each end. RPM2 (Mode 2) This is an auxiliary RPM limiter that is activated when you apply 12 volts to the "RPM2" terminal on the top-side connector. This The connector and mode descriptions are listed below: could be a burnout limiter. When selected, it over-rides RPM1 (the RPM switch: main engine protection RPM limiter). See example 4. The built-in RPM switch can either turn an electrical load off or on at a selectRPM3 (Mode 3) This is the other auxiliary RPM limiter. It also is activated by ed RPM. See below for more detail. 12 volts on the "RPM3" terminal on the top-side connector, and overNC This is the RPM switch (mode 7) relay contact that is normally closed. rides both RPM2 and RPM1. Use this limit as a staging (starting-line) In other words, as long as you haven't reached the point where the RPM limiter. See example 5. RPM switch is active, this contact remains connected to the "common" or "C" terminal. You would use this connection if , for example, High-Speed Timing Retards: you wanted to turn something OFF (such as a nitrous system) when RET1, RET2, RET3 (Modes 4,5,6) These are all high-speed timing retard functions that are activated by 12 volts on the appropriate top-side connector you reached the RPM switch point. See example 1. terminal. Each higher stage over-rides the lower stages, which means that C This is the common terminal for the RPM switch (mode 7) relay in the you set each stage for exactly the amount of retard you want, rather than main unit. It is connected to the RPM switch, where it will switch the adding up each stage to get the actual retard. See example 6. accessory connected to the "NC" terminal OFF, and the accessory connected to the "NO" terminal ON when the RPM switch value is NOTE: When you apply 12 volts to RPM2, RPM3, RET1, RET2, or RET3 the reached. The "C" terminal can be used to switch either to power or display will switch to show that function. If you have both an auxiliary RPM limit AND a retard selected, the display will show the retard value. ground. NO This is the RPM switch (mode 7) relay contact that is normally open. In other words, as long as you haven't reached the point where the RPM switch is active, this contact isn't connected to the "C" contact. You would use this contact to turn something ON (such as a shift light or an air shifter) at a specific RPM. See example 2 and example 3. See the accompanying illustrations for some examples of how to use the RPM limiters, the RPM switch, and the timing retard functions. NOTE: When activating Modes 2, 3, 4, 5, or 6, the display will change to show the active mode. If more than one mode is activated, the higher mode number will be displayed. Push this button to change the mode FIGURE 4 Push either of these buttons to change the value of the selected mode. (R) NOTE: If any button is held down for more than 1/2 second, the displayed value will change automatically. 4 Additional Functions: The HYFIRE(R) 667C has two more functions that can make the ignition installation and setup work better. One of these is the high-speed advance function. This lets you put small amounts of timing in the engine after the torque peak to pick up a bit of horsepower. There are three things that need to be set up for this: the cut-in RPM (mode 9), the maximum advance (mode A), and the slope (mode 8). The cut-in RPM is the RPM where you want the curve to start working. The slope is how much the timing will advance every 1000 RPM after the cut-in RPM. The maximum advance is the highest amount of advance you want the system to reach. For example, say that your engine has the torque peak at 6500 RPM, and you want to add some timing after this. You might want to start adding timing after 7000 RPM, so this becomes your cut-in speed. If you then want 2 degrees additional timing at 8000 RPM, then the slope would be set for 2 degrees per 1000 RPM. However, let's say that you don't want more than 2 degrees of advance, so you would set the maximum advance at 2 degrees. See example 7 for more detail. The other additional function available is trigger compensation, which is set when the mode indicator is "b". This lets you compensate for the various delays in ignition timing caused by both electronic and mechanical changes. To set the trigger compensation, set mode 9 to 5000 RPM, and mode 8 to zero. What this does is tell the system to start the high-speed advance at 5000 RPM, but with a slope of zero, there should be no advance. Once the system is set up this way, watch the timing as the engine revs past 5000 RPM. If the timing does not stay at a steady value (once the 5000 RPM point is reached) then adjust the compensation value until it is as flat as possible. For example, if the timing retards slightly as the RPM goes up, increase the compensation value. If the timing advances slightly as the RPM goes up, decrease the compensation value. NOTE: This function is only valid for RPM above the highspeed advance cut-in RPM. If you have the high-speed advance cut-in set above the normal operational range of the motor, the compensation function does nothing. Once the compensation is set, then the high speed advance settings will be accurate. The factory setting should be correct for most types of flying magnet type crank trigger systems, and should not normally need to be adjusted unless you are using a different trigger type. Number of cylinders selection The final mode that can be set is mode "C". This allows you to select 4 through 12 cylinder operation. This ensures that the RPML and the timing are proper for the engine. Mode 6F is special - this is for odd-fire V6 engines ONLY! The cylinder firing spacing should be 45/75 (at the distributor) or 90/150 at the crank.
