I think there is an issue with some of those links, but there is some re-branding efforts going on with the scangauge.

It is paired with some fuel thingy that costs $200+ dollars though, and some "drive smooth" tips like that kiwi game, which is not always the most efficient way to drive.
The fuel thingy looks like it started out life as a thing you put in your lawn mower gastank to keep the fuel stabilized over winter, can't say what it does and under what conditions it does it, but %3 better mpg on my bike would be about $10/year savings so it would pay for itself in 20+ years (2+ years if you get 10mpg), and it is a pretty big maybe till I see someone independant that I know who understands what the thing does and knows how to test, tries it out.
