In Japan, Your Nissan Helps You Drive Efficiently

Nissan just announced that users of its popular CARWINGS navigation system (only in Japan for now) will now have access to a new service called "Eco-Drive and You". There are three main components: 1) Eco-drive check, which shows your average fuel consumption, trends in fuel economy, a history and comparison with the last 2 records; 2) Eco-drive ranking, which shows your average fuel economy history and compares it with other CARWINGS members with the same car model, and displays annual fuel expenses and savings; 3) Driving Advice via audio guidance, various tips on more efficient driving.
Please Nissan, don't keep this technology Japan-only! Real-time feedback has proven to be very effective in making people more efficient drivers (in the Toyota Prius, for example). It's a lot easier to improve if you know exactly how you're doing... ::Nissan Press Release, via ::Green Car Congress.

Will show instant MPG (L/100km)
current trip MPG
today's MPG
and MPG since the last fill-up.
Will clear "check-engine" codes
Will show readings from every sensor on the engine.
To me it was the best purchase I ever made, showing me where I got bad MPG over my trip to work.
fit in every car made after 1996, installation took less than 1 minute including finding where is the OBD2 connector under the console. no screwdriver or tool needed. it's simply plug-and-play
