by sitting still in the car with the engine turning on.... i really don't understand how any of that screen is confusing.. unless you don't understand what a Wh is.... (if so, you must not pay an electric bill...)
This also happens on a big hill descent. Theoretically if your descending a big hill for over 5 min and the engine never turns on then you dont burn any fuel. This happened to me this past weekend on a trip from San Diego to Phoenix.
Shoot that is nothing it was taken at the beginning of April. That'll bee the cool temp/night time in another month or two.
But, if you don't burn any fuel, yet you are moving and covering a distance, similar to coasting, the gage should read 99.9 as in any other condition where the instant reading is that.
Would you care to explain that V8Cobrakid. If you are just sitting still in the car with the engine idling then you are NOT regenerating. Please do explain how you can regenerate 100 W-hrs under these condidtions!
