Thanks for that, didn't realise you could do it. Just one question though, with the instantaneous fuel, it displays it in L/h. I know the 3 display clusters display instantaneous fuel in L/h only when your stationary... when you start moving, it changes to L/100km. So when i'm moving, is it actually L/100km or is it still L/h?
It'd be giving you your instantaneous L/100km while you drive. Try driving at 3000rpm in 2nd, then try the same in 4th - It should give you a different reading. Haven't bothered myself, i just found the menu whilst trying to turn off that annoying rest reminder - if i was worried about fuel i'd have a yaris or a colt..
My friend showed me in his VU ute that if he went down a hill in gear it seems the injectors stop pumping as a reading of 0L/Min comes up - explains why the ute seems so hesitant to speed up rolling down hills.
OKAY i checked and it does NOT give the correct reading. It actually gives it in litres/hour not litres/100km.
Basically, in the WL Caprice (which has the 3 digital displays) when you are stationary the instantaneous fuel displayed on the additional display is in litres/hour. When you start moving it changes to litres/100km. On the contrary, the instantaneous fuel on the main display (though mode+set) always stays in litres/hour... because it is in litres/hour!
Now to explain... i held down mode+set when i started the car to get instantaneous fuel reading on the main display, and as expected, it was the same as the additional displays instantaneous fuel (as they were both Litres/hour and i was stationary). However when i started moving, i noticed the additional displays instantaneous fuel was higher than the instantaneous fuel on the main display.
So for example, if i were doing 50km/hour, the instant fuel on the main display is half that of the additional display. Because in 1 hour (litres/hour) i travel only 50kms... hence using half the fuel it says on the additional display which is in litres/100km.
Basically, the instant fuel displayed through mode+set is only true for cruising at 100km/h... otherwise it is necessary to do the calculation in your head.
So if you cruise at 25k/h, and it says your using 3 L/hour... you are actually using an instant fuel of 100/25 * 3 = 12 L/100km.
