I'm going to add "HX" to your thread title to get the attention of the other HX owners.

If you want an accurate MPG gauge, you need MPGuino. The ScanGauge or Ultragauge do not calculate MPG properly when in lean burn mode because MPG is calculated from air consumption based on a ~14.7:1 ratio.

The other gauges & features of the SG/UG etc. are interesting though.
