MCU-300 Engine Control Unit

CHASSIS CONTROL UNIT

MCU-300

MCU-300 is a compact, self-contained controller and data logger for chassis management applications in top level motorsport. It includes many innovative features that make it our most powerful and advanced chassis management system.

In Formula 1 applications MCU‑300 would typically be used with the TAG-300 engine management system. MCU-300 is configured by System Monitor and the logged data is in a suitable format for display and analysis by ATLAS.
