TAG-400 Engine Control Unit

ENGINE CONTROL UNIT

TAG-400

The TAG-400 is a compact, self-contained engine management system and data logger for race engines up to 8 cylinders. The unit is complete with integrated ignition and injection drivers and so needs no external units to run an engine.

The unit is suitable for controlling high-revving motorcycle engines plus normally-aspirated and turbo-charged rally, sportscar or open-wheel racing cars. Advanced traction control, Knock control and quickshift features can all be provided, where permitted by regulations.

The TAG-400 exploits Power PC technology to provide a powerful and flexible platform for extracting the optimum performance from an engine. Turnkey systems or customer prepared applications are both supported.
