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

The TAG-400N exploits Freescale Power architecture 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.

In 2013, NASCAR completed more than one million Sprint Cup Series competition miles without a single engine controller failure.
