"The New ScanGauge-e display.
Linear Logic makers of ScanGauge II, the easiest to use fuel economy feedback device today, announced the release of the all new ScanGauge-e. For the initial launch Linear Logic is sponsoring the CleanMPG Fuel Economy Adventure Challenge.
The EcoBoost Challenge will begin on April 30 in Los Angeles where a team of seven CleanMPG drivers and three guest journalists will set out on the cross country adventure. The ScanGauge-e will help the team attempt to achieve greater than 30mpg from the 22 mpg highway rated 2011 Ford F-150 with the 3.5L EcoBoost engine. This is Ford's most powerful (365 HP and 420 lb.-ft. of torque) and most fuel efficient truck engine ever built.
ScanGauge-e overview
Following in the footsteps of the award winning ScanGauge II, the all new ScanGauge-e features more than 18 built-in digital gauges in the standard or metric format. In addition to dual gauges, the ScanGauge-e provides real time fuel economy feedback that is displayed in a unique to the industry graphical format. The recently achieved fuel economy display period can be adjusted to show from approximately 10 seconds to 5 minutes.
