Description

The Megasquirt MicroSquirt ECU is a fully assembled, entry-level engine control unit with a universal 8' wiring harness. It is designed for a wide range of applications, from powersports and single-cylinder engines up to 8 cylinders. The MicroSquirt offers up to 2 fuel and 4 spark outputs, supporting over 40 ignition modes and various fueling strategies like speed density, alpha-N, or MAF-based systems.

This versatile unit can also function as a standalone transmission controller or a CAN I/O expansion module. Its firmware supports numerous electronic automatic transmissions and can integrate with other ECUs via CAN bus. As an I/O extension box, it can enhance the capabilities of MS3 or MS3Pro ECUs by capturing and logging vehicle speed and additional sensor data.
