Megasquirt EFI Introduction

Megasquirt ECUs are a range of affordable aftermarket fuel injection and ignition control systems. They support a wide range of engines and have many race features built-in.

Entry level systems give excellent value for money and good live tuning ability. High end systems give the advanced user additional inputs/outputs and control features. For the DIY enthusiast, there are options to buy the ECU in kit-form and assemble it yourself. Other customers will prefer one of the fully assembled options. Your supplier can help you choose which option suits your requirements and budget.
