Sorry to mine the thread, thought it was better than creating a new one. Worked my economy out to be about 13.3L\100 overall, can now get close to 400km out of a tank of fuel.
Question is, why is the lancer so called "trip computer" so crap? I can't seem to find a setting where it will not reset the fuel usage everytime the car is turned off\on or after certain amount of trips. No function for litres used, kms travelled, instant economy. Just a dodgy range forcast (worst I've seen is it saying 60kms when I had half a tank left)... my old magna had all the mentioned functions on it's trip computer.
I live in a hilly area, so of course the consumption is going to be crap to begin with if not a long trip, the arrow constantly lives on the right hand side of "20" on the stupid green\white line annoyance. Is there a setting I've missed to make the fuel economy function last more than 5 mins or for the one trip? Read the manual and seems there isn't, but it can't be that crap in 2015 can it?
Also thinking of getting one of these if all else fails:
http://obduino.ca/ anyone else used something similar? just want an accurate measure of how much fuel is being used as can't rely on the car to tell me properly. Found out that when the "refuel now" comes on, I have about 10 litres left, but that's about it.
