Note: Solid core spark plug wires cannot be used with an MSD Ignition Control.

Note: A crank trigger is recommended to supply the input signal to the Power Grid Ignition System to ensure the most precise timing and rpm control.

OPERATION

DIGITAL OPERATION

The MSD Power Grid System Controller uses a high speed RISC microcontroller to control the ignition’s output while constantly analyzing the various inputs such as launch, burnout, and step wires; trigger signals, rpm, and CAN-Bus data. The high speed controller can make extremely quick updates to the ignition output, timing, and rpm limits while maintaining +/- 0.1° timing and +/- 1 rpm resolution. The circuits and controller of this system have been designed for superior protection against Electro Magnetic Interference (EMI).

The Power Grid System Controller, PN 7730 / PN 77303, is designed to be used with the Power Grid-7 Ignition Control, PN 7720. This is a high output CD ignition control. The Ignition System allows for the System Controller to be mounted on top of the Power Grid-7 to save space and provide a neat, compact installation. The System Controller can also be used with other MSD Ignitions such as the 7AL-2, MSD 8-Plus, and the Pro-Mag series. In order to use the rev limiting features of the System Controller the paired ignition must have a built-in Soft Touch Rev Control that uses plug-in RPM modules. Pages 10-12 show wiring diagrams for a variety of different ignition options.
