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, 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.
