Arh, maybe not in your market.. My 2006 does have the AVG function, along with instantaneous, and "nothing"The "average" function was not there in 2006. It appeared in either 2007 or 2008, I can't remember which. The display only showed "instantaneous" in 2006.
Have you tried resetting the AVG display when you fill up the tank?Avg on mine is some random number generated when I push the button. I have full records of all fuel thats gone into my car since new. The onboard computer has 'never' been right.
Kev, yes of course we all know the fuel gauge is inaccurate which is why I haven't mentioned it in my post. My point was that the variation in error I've seen can be explained by the varying fill levels at the filler opening due to the gas pump's automatic shutoff.Kiwi,
The amount you put in the tank shouldn't matter. The ECU couldn't use the gauge for the calculation because fuel tank level indications are notoriously inaccurate. The ECU should be basing its calculations on very exact figures gathered from the fuel injection system. The ECU is supposed to be metering fuel to each injector precicely. The ECU should know to within a few ml exactly how much fuel it has delivered and it has access to the same distance traveled into we have.
It should be able to calculate correctly.
This is the bit I don't understand. The ECU wouldn't know or care how much you put in the tank. Any correlation you see is purely coincidence. The fuel gauge, even if it was a perfectly calibrated instrument, can never be accurate enough. Simply parking on anything less than a perfectly flat surface will introduce inaccuracies.My point was that the variation in error I've seen can be explained by the varying fill levels at the filler opening due to the gas pump's automatic shutoff.
Hi again Kev, I'm not sure why you keep mentioning the fuel gauge? There must be a misunderstanding there. Nothing here is relevant to the fuel gauge - not the digital economy readout nor how the tank is filled to the top. It simply reads the current passing through the pair of resistive float levels and stands alone in its uselessness.The fuel gauge, even if it was a perfectly calibrated instrument, can never be accurate enough...
I do find it very useful.I have tried, no real change in accuracy. Being wrong by .5l/100 it may as well be out by 5. I don't see any point in the readout actually. If you reset at every tank why not just do the calculations manually anyway?
I think it's nothing more than a gimmick and completely unreliable.
