MSD Data Acquisition Module

MSD Data Acquisition Modules: Racing Intelligence Built Into Every Run

MSD has been a cornerstone of performance ignition and electronics engineering since 1970, when it pioneered the world's first multiple-spark, capacitive discharge ignition system. Over the course of more than five decades, that relentless drive to push performance boundaries has expanded well beyond ignition boxes into a full ecosystem of race-day electronics — including the Data Acquisition Module category, where MSD delivers the same race-proven precision that professional teams in NHRA, NASCAR, and beyond have trusted for decades.

The MSD Power Grid Power Module: DAQ at the Core

The centerpiece of MSD's data acquisition offering is the Power Grid Power Module (P/N 7764 / 77643), a component that blurs the line between power management and data logging. At its heart, it is a fully programmable, four-stage solid state relay rated at up to 80 amps total capacity — handling up to 20 amps per channel — but its data acquisition capability is what sets it apart for serious racers.

When paired with the MSD Power Grid Controller (PN 7730), the Power Module activates its built-in data acquisition system, which records input activations, output states, and temperature readings in real time. Crucially, it logs key race metrics including time from launch, as well as the precise time and RPM at which each channel activates and deactivates — giving tuners granular, lap-by-lap insight into how every accessory system is behaving under race conditions.

Programmability Designed for the Racetrack

What makes this module compelling from a data standpoint is how tightly its control and logging functions are integrated. Outputs can be configured as simple digital ON/OFF switches or as Pulse Width Modulated (PWM) signals with user-programmable frequencies up to 10 kilohertz. Trigger conditions can be set by time, RPM, or temperature — meaning the module can manage fans, fuel pumps, nitrous systems, throttle stops, and more while simultaneously logging the results of each decision.

All programmable features are configured through MSDView software, which also provides a real-time monitor window so users can observe the state of inputs and outputs during setup. The module operates in two modes — Stand-Alone or Power Grid mode — and self-detects which environment it is connected to via the CAN bus, offering flexibility for both bench testing and full race-day deployment.

Why MSD for Data Acquisition?

• Race-validated ecosystem: The Power Module is purpose-built to communicate within the MSD Power Grid CAN-bus architecture, ensuring seamless data flow between ignition, timing, and accessory control.
• Eliminates legacy hardware: The solid-state relay design does away with electromechanical relays, fuses, and timers, reducing potential failure points in high-stress racing environments.
• High-speed data logging: A high-speed data logger records all module functions when paired with the PN 7730 Power Grid, providing the detailed post-run analysis that modern racers depend on.
• Dual availability: Available in red (P/N 7764) or black (P/N 77643) to suit different build aesthetics.

For racers who want their power management and data acquisition working as one cohesive system, MSD's Data Acquisition Module lineup represents the logical extension of a brand that has been engineering race-winning electronics for over half a century.
