MS3 PCB3.0 Unassembled Engine Management System Kit

The MegaSquirt-3 PCB3.0 UnAssembled Kit provides all essential components to build a fully featured MegaSquirt-3 Engine Management System on a PCB Version 3.0 board. This kit is ideal for DIY enthusiasts and advanced tuners looking for a customizable ECU solution. Included in this comprehensive unassembled kit are a genuine B&G V3.0 PCB board, an MS3 Daughter Card, and all standard components per the Bill of Materials (BOM). These basic components include a 2.5 Bar MAP Sensor, PWM Flyback Damping Circuit components, Hall Sensor/Coil(-) and VR Sensor Ignition Trigger components, and Current Limiting Circuit components. The kit also features a machined aluminum enclosure with pre-machined endplates, a heatsink bar, heatsink compound, and jumper wire for custom connections. Users will need to provide their own tools, solder, and assembly time. While the core MS3 ECU offers 16x16 VE and ignition tables, high-resolution tuning (0.1% fuel, 0.1° ignition step sizes), a built-in USB port, and an onboard SD card slot for data logging (SD card not included), full functionality can be unlocked with the separately sold MS3X Expander Board. The MS3X board enables 8-cylinder sequential injection and 8 ignition outputs for coil-on-plug (COP) setups, along with advanced features like nitrous control, 2-step, and launch control. Additional components may be required depending on your specific setup. A tuning cable is recommended if you do not already have one. The BIP373 Coil Driver, sold separately, is only needed when controlling dumb coils directly without an ignition module; it is not required for smart coils or those with external modules.
