Sorry Kev but us posh tw@s with the higher spec screen can use the remote to change a couple of settings. we can reverse the colours, so that we have a negative version of the usual screen, and we can adjust the brightness in the menu. But I've also just discovered that we can adjust the brightness at any time just by using up and down on the remote, i.e without having to go into the menu.

Still no "dim when the lights go on" setting though, which is a bit pants.

Heres a pic of mine, colours reversed and dimmed about half way.

So you're saying the problem is your display doesn't show anything between *somewhere in the 200s* and 999 mpg? That's easy to explain - it probably can't measure that small amount of fuel, even if you could manage to get such a small amount through the injectors in a 1 second period (or however long the D9 computer has between samples)

There is such a thing as unsigned char and signed char, chars are normally unsigned thou. I din't mean integer as these are normally 16 or 32 bits depending on the architecture your using.

Good point about floating point number, had forgotton that the mpg displayed floating point, with the limited accuracy thou they may use a fixed point system.

Was just a suggestion for a possible reason, never investigate what is in there. Quite possible that in later system they have a number of micro contollers, instead of a single controller and have a small controller for calculating this. Probably not thou, but we all know what the french are like with electrics and electronics!

By the way, the reverse colours lasted about 24 hours! I don't like it

I'll live with the lines

Doesn't the MFD dim down with the dash dimmer doodad?

I have to say that front seat passengers get faces brighter than a Baboon's arse on an unlit road at night

Come on dude, keep up!

The reverse colours for the MFD, see the pic up there

Edited to say:
Oi Welly, stop editing your posts. It ruins the flow!
