ECUMaster – Expanding the EMU PRO Ecosystem

Diesel Driver for EMU PRO

Developed to bring full standalone control to modern common-rail diesel engines, the new ECUMaster Diesel Driver expands the capabilities of EMU PRO to include high-pressure diesel injection. This advanced module supports peak current control and precision timing required for diesel solenoid injectors, enabling professional-level tuning for motorsport and engine conversion projects.

Gateway Lite

A cost-effective CAN gateway designed for simple network translation and data management. Gateway Lite allows users to bridge multiple CAN networks, convert message formats, and manage data flow between devices such as dashboards, ECUs, and loggers. Compact, reliable, and easy to configure, it provides professional functionality in a smaller, more affordable package.

CAN I/O Module

This modular expansion device adds configurable analog and digital inputs and outputs over CAN, offering flexible system scaling without complex rewiring. Ideal for advanced data acquisition, sensor integration, or system control expansion when paired with EMU PRO, PMU, or ADU systems.
