MS3Pro Module

Build your own ECU around the same powerful MS3Pro core used in our MSPNP-Pro systems. The MS3Pro Module V2.1 is the heart of the MS3Pro system—an assembled, compact ECU core that replaces the traditional AMPSEAL connectors with 0.100″ pin headers. Designed for flexibility, this module gives tuners, builders, and manufacturers the power of MS3Pro in a form that’s easy to integrate into custom or OEM-style enclosures. This is the same core board used in our MSPNP-Pro ECUs. Whether you're prototyping a plug-and-play solution, developing a private-label ECU, or building a one-off for motorsports, the MS3Pro Module provides a clean and powerful platform. Common Use Cases: Design plug-and-play adapter boards to connect with factory OEM harnesses Install in stock ECU cases to meet racing class rules (e.g., SCCA Street Touring) Private-label ECU production with your own enclosure and branding Custom expansion PCBs with added features like high-current drivers or CAN-based extensions The compact 5.5″ x 3.5″ size makes it far easier to work with than building around the full-size MS3 + MS3X + V3.57 combo, especially in space-constrained builds.
