to truly calculate FC, u should do it when refueling ur fuel..
take KM traveled, divide with Liter of fuel pump..
its more accurate that way since computer doesnt calculate the fuel used during startup.. it gets more inaccurate when u reset the FC meter while driving half way..
as mirage claimed 21km/l most owner got 14-16km/l (using refuel calculation)
if they reset halfway.. the figure can go as high as 26km/l..
so is always better to do manual calculation when pumping fuel.

Mine does - by all means it should unless for some reason urs does'nt perhaps coz of the rigging?
Whenever I do a restart, FC drops dramatically though nothing happened or moved (unless my figures have been averaged over an extended duration). Anyway - engine starts are a constant not a variable (thus you can exclude the constant, unless you're trying to measure how much minyak is used for 1000 engine starts or someting tying directly to restarting the engine, e.g. during idle or at traffic lights), whether your foot is heavy, or not - meaning that however you try to get around it, you still have to start your engine the same way unless you are trying out a new 'supernatural instant big boom spark plug'.
Resetting in the middle of the drive is of course not accurate, cause you are getting a reading at cruise speed which is always the optimum. My Myvi gets 26.5km/l at cruise speed, but because of other causes, e.g. slowing down, traffic lights, tolls my best average on the highway comes at 23.6km/l.
However, it is accurate to say that at 80kph, my Myvi runs 26.5km/l at that constant speed at gear 5 at 2k rpm, for example.
You won't get 26km/l with 4th gear, much less 3rd, or any of the time you are accellerating - by all means accelleration digs the tank like hell. Every stop I make = loss of 1km/l to regain 80kph on a 50km journey.
If I averaged all driving, it would go closer to 17km/l cause of my short city stints (yeah they drag it down so bad).This post has been edited by Dezs: Mar 14 2013, 04:06 PM
