Hello people, just wondering how accurate fuel computers are as mine
has been giving out strange readings such as miles left in the tank and average economy mainly. When I fuel up does not make much diff to the said miles in the tank until after driving it for a while then starts to change.
Seems a bit slow in taking up readings recently. Been doing lot of town driving if makes much sense. Not too concerned if fuel computer is not working properly. Car is a S2 Turbo. Tks all help.

 

British rail is more accurate than one of those fuel/trip computers

Honestly, i reckon i could vouch for 80% of the peeps on here that they get binned in favour of mounting a boost guage there instead

 

i wish i knew this earlier as i bought one of ebay the other day

 

Mines not that bad, although i know my car does do about 15 to the gallon!! I just make sure that as soon as it gets to around 20miles left, i aint got long!!

 

I have had 3 S2's, not one has had a fuel comp I can't vouch myself but everyone I know has said they are well out and always beeping when they shouldn't be n stuff

 

 

i have one on my s2 and i would say its about 75% accurate. its okay but i would still prefer a boost guage there
