Classic MegaSquirt 2 PCB3.0 UnAssembled Kit w/ MapDaddy4 Upgrade

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.
