Euro fuel consumption

Actually thinking about it now, a dyno graph won't prove anything because that is at full throttle which relies on the fuel maps and not the O2 sensor. Your best bet would be to get a known working Euro primary O2 sensor and swap it over for a few weeks.

Exactly. If the O2 sensor is shagged the ECU often reverts to the richest mixture it can. It doesn't just make plus/minus 5% changes. It's the simplest thing, so start with that.

If it's still funny, take it on a highway cruise at 110 km/h for a few hours and see what your economy is. That figure will be a lot less variable.

you dont need a few hours cruise to tell you that..... a 5-10 minute drive would do the trick. Drive on a highway at 90-100 constant and reset the trip, after 5-10 minutes, you should know the fuel consumption

hey, just a simple add to this, i run euro 2006 lux/satnav too, usually do 5-10 min/trip every morning to drop my gf off, my meter was reading around 12-14 Ltrs/100 Kms too

it seem like even if i drive slow like 50-70, my meter was reading around 12-14, but when i rev its the meter seem to remain the same or sometime even goes down by like between .1-.3

is there something wrong with my o2 sensor too?

PS: i've never run euro before, hence i don't know what the average for this, [ MY CAR IS AUTO], but according to the adv it said euro only take about 8.9 ltrs / 100 kms

Thanks craddaz & flipmods & tron7 - my consumption figure is from calculation - the 'i' indicator seems to correlate reasonably. Will try 98 (S8000) next time - using S6000 now. Havn't tried Shell.
Honda says poor figure must be due to my driving (short runs & cold starts) - I will keep a log of trips next fill up.
Re the dyno chart - I'll try photographing it (digital) & with advice as to how, I'll post it. Honda wont release their dyno charts so cant compare.

Looks like I need it (good luck)

I'll try that too - thanks
My dash indicator seems reasonably accurate but my figures are based on calcs;

Mainly from short drives mate.

Sounds like the same scenario as i posted above; as my work mate, his wife drives down to the shop which is like <5mins and back up; then followed by picking kids up from school every weekday.

Reset your average fuel consumption and use that number over a whole tank. The instantaneous fuel consumption is not a good indicator of your average fuel consumption.

You can upload it to imageshack.us and then post the link in here.

My son says to reset the ECU by pulling a specific fuse for app 20s - possible a bad fill may have caused ECU to change setting to compensate - but ECU setting have been checked as ok - if I do a reset is it necessary to have key turned to ignition?
