Overview

The DIYAutoTune MS3Pro Module is a compact ECU core featuring MS3Pro circuitry on a board with 0.100? pin headers instead of AMPSEAL connectors. It serves as the core for MSPNP-Pro systems and is also available for public use.
Show original supplier description
The DIYAutoTune MS3Pro Module is an assembled, compact ECU core that utilizes the powerful MS3Pro circuitry. Replacing traditional AMPSEAL connectors with 0.100″ pin headers, this module offers significant flexibility for tuners, builders, and manufacturers. It is the same core board found in DIYAutoTune's MSPNP-Pro ECUs, making it suitable for prototyping plug-and-play solutions, developing private-label ECUs, or creating one-off systems for motorsports. The MS3Pro Module's common applications include designing custom plug-and-play adapter boards for OEM wiring harnesses, fitting it into stock ECU cases to meet specific racing class rules like SCCA Street Touring, facilitating private-label ECU production with custom enclosures and branding, and enabling the creation of new PCBs with additional features such as high-current drivers or CAN-based extensions. Measuring approximately 5.5 inches by 3.5 inches, its compact size makes it significantly easier to integrate into projects compared to using a V3.57 main board, MS3 daughter card, and MS3X combination, particularly in space-constrained applications. While the module is complete enough to function as an ECU by soldering a harness directly to it, it does not include a TunerStudio license. However, the free version of TunerStudio MS is compatible, and users can unlock advanced features by licensing the software.
