MPG Computer

[RadCordy]

How does the MPG computer work? Does it work off the gear box??

I know that when you put big wheels on a small car the speedo reads wrong by a few percent. my question is will this work the same with MPG on the computer?

I struggle to get over 30mpg in my cordy and was wondering whether the 17's could be causing the computer to think its not travelled as far as it really has?? :confused:

test it out.

fill your car to the brim, then drive it about normally & then fill it up again, noting the mileage between the fill ups & also the number of litres used.

www.seatcupra.net/files/mpg.exe is a handy took mark sheerin knocked up to work it out.

you'll loose mpg with the bigger wheels (or so i have each time) due to increased rolling resistances.

30mpg aint that bad. i get 15mpg from my 1.4 :)

34mpg was the best I have EVER had and that was not easy.

I find the comp. to be pretty acurate. The autonomy counter is a bit off especially when the is in reserve (a couple of quick bends and it goes from 30km left to 0 and back to 30).

I've notice the l/100km go down by just switching from 205 to 225 (both on the 17's).
