The MSD Power Grid Ignition Controller builds on the Programmable 7-Series ignition line with an efficient 32-bit microcontroller and Windows-based MSD View software. This black-housing version mounts directly to the Power Grid-7 box and uses CAN-Bus technology to simplify accessory module wiring, with a removable micro SD card for ignition data acquisition.

FAQ
What does the MSD Power Grid Controller (PN 77303) do?
It's the programmable brain of the Power Grid Ignition System in a black housing, using MSD View software and a 32-bit microcontroller to manage timing, rev limits, and shift light settings.
Is this compatible with the Power Grid-7 box?
Yes, the controller is specially designed to mount to the Power Grid-7 box while remaining compatible with other MSD ignitions.
How is data recorded?
Ignition data is captured on a removable micro SD card for easy storage and review.
What's required to add accessory modules?
A 4-Connector CAN-Bus Hub, PN 7740, is required to attach additional Power Grid modules.
Is this part legal for street use?
No. It carries MSD Emission Code 4 and is legal for Racing Use Only vehicles, not street-driven emissions-controlled vehicles.
