One of Efficiency’s most simple and useful features is it’s Eco Meter. The Eco Meter is just a part of the background. Changing colors to inform you wether you are inside or outside your target Green Zone (see description below). The color changes give you the ability to quickly know your green zone status without the need to interpret numbers.
Green Zone refers to a range within a parameter you believe can help you save fuel. The following parameters are available to choose from: Instant Economy, Vehicle Speed, Engine Load, Throttle, and RPM. For example, you can set it up to RPM so that you’re Green Zone is between 800 and 1500 RPM’s. More or less would mean you’re either idle or speeding to much (these are sample values only). As you can imagine there are several ways to configure your Green Zone and EcoMeter. By default the Eco Meter and Green Zone are based on Instant Economy.
In addition your Green Zone progress is tracked by the Star Rating System and Green Zone % gauge (if enabled), both tell you what percentage of your trip you’ve driven inside your Green Zone. To can adjust your target green target zone to make it easier or harder and increase your % according to your criteria.
For beginners we recommend setting up your Eco Meter as follows:
- A- Find out your vehicle’s combined fuel economy. If you don’t know this value you may be able to find through this web site: http://www.fueleconomy.gov/feg/findacar.htm
- B- Once you know your combined economy go to Preferences and scroll down to the the EcoMeter section. Then click on Base Eco Meter On and make sure it’s set to Instant Economy
- C- The next step is setting your target Green Zone. For your Green Range Minimum enter your combined fuel economy minus 25%. (ex. 30MPG – (30 x .25) = 22.5). For your Green Range Maximum enter 99.
- D- Finally for your Light Blue Warning enter half of the value you entered for your minimum. (ex. 22.5 / 2 = 11)
It is highly recommended that adjust these values after calibration to reflect those changes. For help with calibration go to the Vehicle Calibration page.
