    Was exploring that in depth for a month or so! Paid for it at the petrol station, but not a heavy burden really.

    Lots of fun!

    (Edit: should add that the subtly taller gearing with the larger 255/85R16 tyres fitted works very well with the BAS 170AB tune - hits some kind of sweet spot ...)

    Happily a Bas remap has several benefits
    More vroom
    Better gear changes
    economy
    And cleaner oil with EGR closed
    By all means get a Defender. If you get a good one, you'll be happy. If you get a bad one, you'll become a philosopher.

    Running a steel expedition roof rack and side awning, ARB steel bullbar with Warn winch holding steel cable and Conti 235/85/16 AT.

    No correction to Odo readings, but how much difference would it make? Obviously using different fuel pumps which may cut off at different levels (always filling to first click) and odo reading could be just a smidge from going from say .6 to .7 etc.

    On my vehicle with 235/85R16 tyres the variance was approx 5%. (Totally unscientifically tested by repeated observations over months against GPS speed indication)

    If true - a 5% speedo error can mean a 100km trip being recorded on odo as 105km.

    Let's say you measured 10l used over said distance, that works out to:
    9.52l/100km (using odo)
    10l/100km (real)

    Which makes no difference at all if you are just using the numbers yourself as a relative thing (i.e. has my consumption gone up or down).

    That's exactly what I am doing really, to see the difference between vehicle alone against towing the new camper trailer.

    How confident can we be that the Gps is accurate within x%?
    I have no knowledge either way

    According to our GPS when the Defender's speedo reads 100 the actual speed is about 95, so you can cruise at indicated 105 and be legal. I seem to remember the GPS signal margin is about one metre but that might not be exactly correct.

    That does not really answer my question,
    Is / why a gps more accurate
    I understand the Gps reported speed is an average, and takes no account on curves on the road, ie point to point.
    A lot of opinions on google, and I believe it is probably quite accurate, more so than the speedo, but no hard evidence,

    Because in Australia speedos are required to over read. i.e. they read 100kph when velocity only 95kph
    Don't ask me why seems nanny state to me.
    The GPS will read accurately because it is not goverened by the same regs

    You won't find me on: faceplant; Scipe; Infragam; LumpedIn; ShapCnat or Twitting. I'm just not that interesting.

    Last time I looked, about 15 years ago, the Australian Standard for spedo's (not the bathers variety) only required an accuracy within +/- 10%....... This because of the various factors involved that contribute to errors. Modern electronic speedo's are supposed to be much more accurate, but are still only within a couple of percent.... And this is all with manufacture's specified tyres, pressures, etc...

    Our problem really starts with radar guns/multi novas/speed cameras on poles/timed distance speed averagers etc.......
    All of these devices are far more accurate than the humble speedo' (not the swimming togs variety). You can now be charged with speeding at only 1kmh over the limit. But if your speedo is telling you, that you are 8 kmh under the limit, you will get really upset.

    So, I believe the consensus among some manufactures is to put speedo's for the next tyre size up into vehicles, as it eliminates much of the risk for them. And hence potential law suits..... An added bonus is the reduced speed in accidents.

    Cheers,

    Phill.
