The MSD-8 Plus Ignition Control is designed for racing applications and offers single or dual coil output capabilities. It includes features such as RPM limiters and cylinder selection programming. Installation requires disconnecting the battery, with the negative cable removed first, and utilizes included components like vibration mounts, RPM modules (3K, 7K, 8K, and 9K), a mag pickup extension harness, and various hardware. The system is not compatible with solid core spark plug wires.
Features and Capabilities
The MSD-8 Plus Ignition Control is specifically intended for racing use. A key feature is its ability to operate with either a single or dual coil system. When configured for a single coil, both coil positive wires must be connected to the coil. The ignition system is equipped with a 2-Step Rev Control, allowing for the setting of two different RPM limits. One limit can be used for over-rev protection, while the second can be activated on the starting line to assist with staging and launch control.
Parts Included
The MSD-8 Plus Ignition package includes the following components:
- MSD-8 Plus Ignition unit
- Mag Pickup Extension Harness (PN 8860)
- Four Vibration Mounts and associated Hardware
- Four RPM Modules: 3K, 7K, 8K, and 9K
- PN 8830 Filter
- Coil Harness
- Power Harness
- A parts bag containing mounts, terminals, and other miscellaneous hardware.
Installation Procedure and Warnings
Prior to installation, it is crucial to disconnect the battery cables. The documentation explicitly warns to remove the negative (-) cable first and install it last. The system utilizes vibration mounts for secure installation. The Mag Pickup Extension Harness (PN 8860) is included for connecting the magnetic pickup.
Cylinder Selection
The MSD-8 Plus Ignition Control can be used with 2, 4, 6 (even-fire), or 8-cylinder engines. The unit is initially configured for 8-cylinder operation. To adjust the cylinder setting for other engine configurations, the cover must be removed by unscrewing a single screw, revealing three wire loops. Cutting these loops determines the cylinder selection, as follows:
- 8 Cylinders: None
- 6 Cylinders: One
- 4 Cylinders: Two
- 2 Cylinders: Three
Figure 1 in the documentation illustrates the cylinder programming configuration.
Spark LED Indicator
The system incorporates a Spark LED that flashes each time the coil fires. This LED serves as a diagnostic tool, confirming that the ignition receives a trigger signal and is functioning correctly. If the coil is not connected, the LED will not flash. When the engine is running, the LED will appear solid.
RPM Module Operation
Module 2 is active when there is no 12 volts applied. The documentation does not provide further details on the functionality or configuration of the RPM modules beyond this statement.
Compatibility Considerations
The documentation specifically states that solid core spark plug wires are not compatible with the MSD Ignition system. This is an important consideration when selecting spark plug wires for use with the MSD-8 Plus Ignition Control.
