The MSx30-Guts Kit includes all of the critical electronic components needed to build out a MegaSquirt V3.0 ECU — minus the PCB and enclosure components — making it a perfect choice for experienced builders sourcing their own case and board.

This comprehensive kit includes all resistors, capacitors, diodes, transistors, integrated circuits, DB37 ECU connectors, a tube of heatsink compound, and a length of jumper wire. It’s the exact electronics bundle included in a full Classic MegaSquirt PCB3.0 Kit, ready for custom applications, replacements, or budget-conscious builds.

Ideal for:

• Rebuilding or repairing an existing MS V3.0 ECU

• Advanced users assembling from modular or spare components

• Educational or development use

What's Not Included:

• V3.0 PCB (main board)

• Case and endplates

• Processor card (e.g., MS1, MS2, MS3)

• Heat sink bar

Build your ECU your way — with flexibility, quality components, and full control over your layout and assembly process.
