    A tweaked GSi trying for the UK land speed record might do it

    is it a zaf a or b?

    if its anything like the astra H i've heard of a few with the fuel comp taking up to 100 miles to update to realise the car has been filled up to update the range, the mpg seems odd though, must be misreading somewhere?


    ill move this thread to the zafira electronic forum tho if its ok as thats where its best suited, any problems with this send me a PM

    Well, spirited driving might cause it to drop dramatically short term. Take it easy and see if it levels out.

    EDIT: ooh, that was weird... I appear to have been teleported into another forum while I was distracted

    Dunno if it's work on yours but what i did with my old vec, was let it run as low as you dare with fuel(carry a can o fuel if you want), then fill it right up. this may get it re-set???

    ooo thats an idea, fill it up and see what happens, mind i can see that working on the range but the fuel consumption bit would still be wrong despite being reset

    mpg, reading 7?? is that what the average says or instant?? once re-set the whole thing it should read however you drive.
