Classic MegaSquirt 2 PCB3.0 UnAssembled Kit

Build your own powerful standalone ECU with this MegaSquirt-II Engine Management System featuring the V3.0 main board. The MS230-K kit provides everything you need to assemble your own MS2 unit — perfect for naturally aspirated, turbocharged, or supercharged engines.

Included in the Kit:

• Genuine B&G V3.0 PCB mainboard

• MegaSquirt-2 daughter card

• Full Bill of Materials (BOM) including:

  • Basic components

  • 2.5 bar onboard MAP sensor (supports up to 21 PSI boost)

  • PWM Flyback Damping Circuit

  • Hall/VR ignition trigger components

  • Current limiting circuits

• Extruded aluminum enclosure (with CNC-machined flanged ends)

• Pre-machined endplates

• Heatsink bar

• Tube of heatsink compound

• Jumper wire

• Female DB37 connector and shell for your harness

⚠️ 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.

MegaSquirt-2 Key Features:

• 24 MHz HCS12 processor

• Fuel control to 1 µs resolution (100× more precise than MS1)

• Full ignition control (advance, dwell, spark) for:

  • Single coil/distributor (e.g. 7-pin HEI)

  • Ford EDIS systems

• 12×12 VE, AFR, and spark tables

• Stepper motor IAC support

• Ford PWM idle valve support

• Built-in rev limiter (fuel cut or spark retard)

• Closed-loop fueling with narrowband or wideband O2 sensors

• CANBus networking

• 115,200 baud serial communication

• Support for:

  • Speed density, Alpha-N, and blended strategies

  • Dual fuel/AFR target tables

  • Proportional EGO feedback

  • Configurable open-loop based on MAP or TPS

  • TPS/MAP-based accel enrichment

  • Real-time or initial MAP-based barometric correction

  • 2 spare I/O lines for custom control
