TAG-300 Engine Control Unit

ENGINE CONTROL UNIT

TAG-300

TAG-300 is a compact, self-contained engine controller and data logger for engine management applications in top level motorsport. It can manage an engine of up to twelve cylinders and includes many innovative features that make it our most powerful and advanced engine management system. TAG-300 can also be supplied with 4 Moog valve drivers, this version has 10 injection drivers.

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