The MegaSquirt-2 Engine Management System (EMS) with V3.0 main board is a powerful, customizable solution for DIY tuners. This unassembled kit includes everything needed to build your own MS2 ECU — now upgraded with a MapDaddy4 onboard MAP/baro sensor for up to 44 PSI boost monitoring and real-time barometric correction.

Perfect for naturally aspirated, turbocharged, or supercharged engines, this system offers fuel and ignition control, closed-loop tuning capabilities, and a flexible foundation for future upgrades.

Included in the Kit:

  • Genuine Bowling & Grippo V3.0 main PCB

  • MegaSquirt-2 processor module

  • MapDaddy4 4-Bar MAP sensor with barometric correction

  • All components per the standard MS2 V3.0 Bill of Materials, including:

    • Basic components

    • PWM Flyback Damping Circuit

    • Hall/Coil(-) & VR ignition trigger components

    • Current limiting circuit

  • Brushed silver aluminum enclosure (MS3-style for upgrade path)

  • Pre-machined endplates

  • Heatsink bar

  • Heatsink compound

  • Jumper wire

⚠️ Note: If you require direct coil control, BIP373 ignition drivers (Q16 and optional spark outputs) are sold separately. These are only needed when running dumb coils without an external ignition module.
