ok I have a question for you all that are smarter than me! on the fuel mileage screen why does the l/100 go up so much when idling? if the bar is say set at 13/100 why does the blue graph thing go way higher than the bar?
When you're idling you are burning fuel while getting nowhere. Since dividing any number of liters by zero distance results in a meaningless infinite number the graph will go up to its highest reading.
For most on these forums the mpg just goes to zero since the distance part of the equation is zero and it doesn't matter how many gallons it's divided by while idling.
Conversely, when coasting downhill our graph will show the maximum while yours probably trends to near zero.
