I see, thx for clearing that up.
Meh using 6th at 50/60km is too much hassle for what its worth anyway, i'd rather use 4th and pay an extra $2 at the pump... It was just a one-off thing I wanted to try.

Ahhhhh, yfin you have answered my long sort after Q, why the Euro has throttle lag. I got a whole lot of waffle from Honda who mumbled about digital equations converting to analogue with a triple bypass and a bowel replacement. So it is the lag from nil fuel to fuel flow, hmm, Honda should be able to resolve that. Thanks for that gem now do you know how to fix the problem? :)Quote:

It actually took me a long time to even notice this was happening it is so insignificant IMO. Play around with how you apply the throttle - sometimes if you are very gradual - ie tiny application and then gradual - there is no jerk at all. Give that a go.Quote:

By the way - I don't know what RPM the injectors cut off when rolling in gear. There might be some minimum RPM for it to happen? There also could be a minimum of time you need to be off the throttle - eg if you are on and off the throttle very quickly - there is no jerk aye? I noticed that. I think the ECU waits to see whether the car is definately going to be rolling in gear without throttle for a mininum set period before shutting off the injectors.
The slight lag when using cruise control doesn't bother me at all. Where I get annoyed is when I am in a parking mode and the car jerks hard when a slight amount of throttle is applied. I overcome this by coasting and feathering the clutch if necessary (which I hate to do). As I drove tourists around Europe I had to learn to drive smoothly that's why this throttle lag bugs me more than most. Maybe a tweak on the ECU might work. I don't think our local Honda dealer is up to it so are there any specialist between the Southern Highlands and Sydney or Canberra??

Possibly because there is fuel still in the injectors and fuel lines no where to go waiting to be burnt.Quote:

Confused? yeah so am I. Are these two different problems or one manifesting in different ways?

I just did a drive from bris to syd then back again over last weekend, fuel economy was brilliant, infact there's probley enough juice to do the ~940k between Sydney and my house on the south side of Bris. Anyway, filled up after some bris city driving after returning, 925km on trip and put 60.51L of BP Ult back in the tank, which by my math is around 6.5L/100km.
Those figures look good but to keep to reality try doing a 4 fill up average driving normally, whatever normally is for you. Someone else said earlier not to tress the engine with too low revs. I seem to think that 2,000rpm is ok on a trailing throttle and 3,000 rpm at least if accelerating. These RPMs may need to be verified by those more enlightened (qualified) than me.

What do you mean by "shuts off the injectors"? Won't the engine stop if the petrol is stopped?Quote:

We just back from Noosa this w/end and got pretty good economy. 450km's on half a tank, 95% highway driving. There were about 10km's of 60km/h or slower on the Bruce Hwy due to too much traffic and about 40km's around Noosa on Saturday arvo. There were of course the occasional VTEC yo! spirts to pass slow drivers :)
Anyone tried the optimax extreme? and a comparison to normal optimax?
I did a mistake today by fueling mobil6000 :( (bloody mobil, it was 4am in the morning and it said premium unleaded until I walked to the next pump and there was mobil8000) I've used half the tank now, reckon i should top it up with extreme to even it out?
