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.Specifications: Product Type: Power Grid Controller Color: Black Current Draw: .5-.7 Amps Operating Voltage: 7-18V Part Number: 77303 Requires a 4-Connector CAN-Bus Hub (PN 7740) to add accessory modules; compatible with MSD 6, 7, 8 Series ignitions or a Pro Mag.Compliance: This part is legal for sale and use on Racing Use Only Vehicles — competition vehicles that are not registered and never operated on the street. It is against the law to install this part on an Emissions Controlled Vehicle (1966-and-newer California-certified or 1968-and-newer federally certified vehicles).FAQWhat 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.{"@context":"https://schema.org","@type":"FAQPage","mainEntity":[{"@type":"Question","name":"What does the MSD Power Grid Controller (PN 77303) do?","acceptedAnswer":{"@type":"Answer","text":"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."}},{"@type":"Question","name":"Is this compatible with the Power Grid-7 box?","acceptedAnswer":{"@type":"Answer","text":"Yes, the controller is specially designed to mount to the Power Grid-7 box while remaining compatible with other MSD ignitions."}},{"@type":"Question","name":"How is data recorded?","acceptedAnswer":{"@type":"Answer","text":"Ignition data is captured on a removable micro SD card for easy storage and review."}},{"@type":"Question","name":"What's required to add accessory modules?","acceptedAnswer":{"@type":"Answer","text":"A 4-Connector CAN-Bus Hub, PN 7740, is required to attach additional Power Grid modules."}},{"@type":"Question","name":"Is this part legal for street use?","acceptedAnswer":{"@type":"Answer","text":"No. It carries MSD Emission Code 4 and is legal for Racing Use Only vehicles, not street-driven emissions-controlled vehicles."}}]}
