    Thats the way all injected vehicles do it Phil ...my understanding is that it is fuel injected or used from the rails if not returned and then tbe straight calculation based on the odometer so as long as the odometer is accurate then so should economy reading. If you hook up a diagnostic tool it should also show liters per 100k on that too and that can be user calibrated for bigger tyres.

    Cheers

    The CCF contains a fuel economy calculation adjustment factor which was factory set at +7% in my D4. Now set at -5% the display is mostly very accurate but can be slightly optimistic or pessimistic depending on driving conditions. It might be less accurate for a vastly different driving style though.

    I have had my D4 just over 12 months and I have had a variety of trips with it and I have kept a spreadsheet on it since new. At 38000k I have an average of 11.16L/100Km and I am very happy with that.
    By comparison with the 3L Patrol I got an average of 12.8L/100Km which has a lot less power and torque and the new Hilux I drive at work is even worse than that.

    Is there much difference in accuracy between different cars? I wonder if tyre circumference differences is affecting the one way or the other.

    Is it difficult to find the setting to change the CCF?
