ScanGauge LINEAR LOGIC SGII

Inaccurate, disagrees with dash and other scan gauges

I've had my ScanGuage II since 2011 and it has performed flawlessly in my 2011 Prius. The X-Guages are super-helpful in monitoring the various hybrid systems and it continually use the RPM, Coolant Temperatures, and HV amp readings to monitor these "hidden" parameters that Toyota wisely left off of its instrument panel (because they fluctuate in a highly unusual way compared to regular vehicles).
