I tried that a few times Brian, but no go.

I guess I'll just have to trust the pump more than my gauge next time!

Hasworked for me in the past. Have quite a high crown on the road i park on so if end up stopped at some of the nearby traffic lights it switch the ignition off and on i normally get a much more realistic reading (i.e. quarter tank instead of empty)

my guess is when you turn the ignition on it takes an instantaneous reading of whats in the tank and then starts a rolling average hence why after a minute or two of driving the level starts to climb

The ECU is definately filtering the values - so it might have been a case of the restarts helping. If it was a simple average a few restarts would have a quick effect - looks like they're using a different algorithm - and that they've been expecting a variance in the readings from the sender. That might be the root problem here - Honda knew they had a sender that suffered a lot from fluctations in readings, but decided to deal with this through software, rather than changing the sender arrangement. Coupled with the ECU's current usage estimation, that would pretty well explain all the fuel gauge behaviour everyone's seen. Doesn't help though - I doubt we're about to figure out the filter algorithm with the little bit of empirical data available.

Oh, well, it's a bit of S2k character!

Weird. Our Celica has always been easy to fill up. Now a Peugeot 206, that's a different story. According to Pug you should "only allow the pump to click off twice, otherwise the tank will overfill". i.e. Fill, click, fill, click.

The problem is that the tank is so badly designed that you'll be lucky to get half a tank filling it this way

I tell you what.

There has been a lot of p-taking on the MG owners thread.

THIS thread belongs in the Civil Service Motoring Association monthly mag.

Along with things like:

My wipers don't clear the bottom half inch of the screen and

Rover 75 owners - how long do your indicator bulbs last?

Ya bunch of nerds

Just fill the bloody thing up when you go to the garage.

Oi Rustington Boy!!
You might have yer money pit in Gad Towers, but ain't NO way I'm putting in a full tank of fuel at 89.9p a thimble!

San, at approx 4ppl that is SFA for a tank full. Even on an unemployeed doctors salary.

If you're that hard up you could always auction those headrests..
