Which is it

[Fatso]

Have only just noticed after 3 yrs of ownership that the fuel reading for instant usage is Km/Ltr , I always read it as Lts/Km , so does this mean Km travelled per Ltr of fuel used . This is arse about to my falcon read out which is Ltr per Km travelled .

[letherm]

Too cold to go out to the car and check at the moment but I suspect that it might be user selectable in one of the menus.

Exactly never taken much notice really of the instant one but ill check later, i hardly use it only keep it on the date and total kms one.

[sniegy]

Should be able to change in the menu to which way you want it.
Cant be moving either to change/enter the menu.

Fatso - isn't your RRS the same as mine - a 07MY??

If so how do you get an instant readout on fuel consumption. Mine only provides an average in mpg or l/100km selectable in the menu - instant fuel consumption is not available - i needed a Scanguage for that until it got blown up by lightning.

Yeah mine is L/100kms checked this morning lol

Unless your RRS trip computer is different to my Discovery, when you scroll through the trip computer options, you get distance to empty etc, one of the read outs is an instant consumption.

And speaking of scangauge, is that more accurate as a trip computer than the LR & if so why. Wouldn't a scangauge use the same parameters to get the information?

Gday , As mentioned above I just use button on end of stalk to set up readouts etc and scroll through to set it up , So one of the options was to get instant fuel , I must have set it myself yrs ago but only just noticed it was reading Km/Ltr not Lts/100km . This is why I thought my fuel consumption went up after blanking the egr , not sure if have Ltrs/100km will check latter . PS I think mine is only average readout not instant instant Cheers

That is interesting - there is no option on my car to select instant fuel consumption, average consumption only. I also checked the Handbook and there is not mention of instant fuel consumption - my car is as listed in the handbook - average consumption only.

Scanguage uses the same inputs but has different formulas for calculating items eg average fuel consumption is worked out from last reset - not sure what the LR one is but is definitely not from last reset - maybe averages last 100km - don't know.

What model Disco do you have - if it is a D3 it should not have a instant fuel readout.

I do not know about a D4 but I do know its message system is different.

My MY13 D4 has instant as well as whole trip. It has 3 meters - auto which resets when you turn the engine off, Trip A and Trip B which you can reset if you want. Trip A and B show instant as well as average too.

They are not at all accurate from my experience and most forum members comments I've seen indicate it's a general thing.

[Fatso]

Should have read the idiots guide to RRS , must have set it up wrong when I got it or the previous owner did , all ok now Lts /100Ks . Don't know why anyone would want Km/Ltr ? , might be an English thing .
Also Garry I have no instant fuel readout , just the ave per 100ks . Al

Truckies like kilometres per litre.
I wonder if kilometres per litre is more accurate then litres per 100.....but I guess they use the same inaccurate formula for both.
Will give it a try and see if there is any difference.

The previous owner possibly went that way because we used to used Miles Per Gallon in the pre metric era and they could relate to or understand Km/Ltr better.

If you want to be more accurate, try using microlitres per millimetre or the inverse of.

Off topic a bit,but i can never find trip 'B'.
it always stays on A.

i have read the manual,fiddled with the stalk,but can't seem to find it.:confused:

On My MY13 D4 HSE it is accessed by pressing the right hand "OK" button on the steering wheel which has 4 directional arrows around it positioned N,S,E and W. That brings up a menu in the dash between the speedo and tacho. One option is Trip Computer. Select that with the OK button and then you will see Auto, Trip A and Trip B. Tab down to the one you want and press OK to select, then back out of the menu. It will now be visible when you press the button on the indicator stalk.

At least that's what happens with mine :)

You just need to adjust the bias, which is likely different between cars, but it's set at +7%. I think I have it at b-3.5%, and over a whole tank, is generally out by no more than +/-0.5L/100km, which is accurate enough for me.

Thanks PHL.

How do you do that? Haven't seen that option in any menus or is it an option in one of the diagnostic tools I read about here.
