Fuel Gauge

[lucagoa]

Hello,

I've a question about the fuel gauge. Is this adaptive? I mean is it showing the remaining miles (km) from the refuelling according to the speed or not? I noticed that from freeway normal speed (In Italy around 120 km/hr) to mountain roads (driving sporty) there is not that much difference. Am I wrong?

I assume you're talking about the estimated range on the on-board computer? After looking at mine for two years now, I think it is making a prediction as to the remaining range based on average speed. I know that if I'm in town the range barely moves, but if I'm wicking it on the highway it drops pretty fast.

I believe Allan is correct on this. Also, for what it's worth, I have run mine down to 19 miles left before making it to a gas station. So, I think it is pretty accurate too. Ride safe,
Hank.

It's measuring the consumption of fuel (it knows the injector size and injector duty cycle) vs the remaining fuel (it reads the fuel gauge).. if the fuel gauge isn't accurate - then the remaining MPG won't be accurate. Theory has it that they're supposed to read 0 remaining when the reserve level is reached (the spec in the US is 1 gallon - at least that's where the dealer is supposed to set it when calibrating the fuel level strip.)

Since I had the software update - mine is considerably more optimistic - and appears to be calibrated so 0 is actually very close to 0 remaining in the tank. If I take it down to 40 miles remaining, I can usually put 5-5.2 US gallons in the tank. Fred H has run his as close to empty as he'd like to - and managed 5.7 gallons.
