Gas mileage
#402
Yes in answer to your question imperial gallons, please bear in mind that the U.K. and European jazz are mostly the 1339cc idsi engines they are 8 valve units with 2 spark plugs per cylinder, the clever bit is the idsi which adjusts the ignition timing of each set of plugs for optimum fuel economy.
the 1339cc unit produces 83 bhp and 119nm of torque at only 2800 rpm, couple that to the 7 speed cvt auto transmision which keeps the revs pretty low you have a really good fuel efficient vehicle, driving normally on open roads i never usually have to exceed 3000 rpm or 4500 for rapid overtaking

All I can come up with is: use of excessive throttle position. The Fit seems to launch just fine for most sitations by just taking up the slack in the throttle. I could see that if I was pushing the throttle halfway to the floor at every start it might kill the fuel economy. That is just a guess. Sorry, but I'm not into experimenting in ways to get worse mileage
Remember that the idea behind VTEC is to give you optimized peformance at botn low speed/low rpm driving and at high rpm/freeway speeds. So let the car do the work and see if you get an improvement in mpg.

That could be it...
Since I started driving "HARDER" the v-tech has been kicking in... and I've gotten a 5 mpg improvement of driving "soft" and not letting the rpm's get over 3000....
As for sitting in traffic - that's negligable.
The first tank I had over 29 mpg I had the car idling for about 6 hours with the heat on (it was colder than expected on a camping trip....)
I've got to admit I was completely shocked by that one...
Idle the car for 6 hours, get a 5 mpg improvement?
Heck... I'll let my car idle while I'm at work all day if that works!!!

I dont think you mean punch it nor floor it. I think what you mean is that others are worrying about hitting vtech RPM and that shouldn't be the case. Just drive like you normally would drive any car. Don't try to keep the RPM under 3k, for all we know, Vtech is whats working to optimize your mileage. When I'm going up a small hill and I do it lightly, I noticed that it revs up, then back down, then revs up again wasting gas. I think the car revving up and down is what's killing your mileage.. If you just drive it like you normally do, the momentum will put less drag on the car. Since our cars are so light, once it picks up to speed, it is effortless to pull it's weight and thus saving you gas.

The second time this summer, my Jazz did cross the 700km border with the same filling.
And the most I ever could refill was 38l.
The best is 5.2 l/100km and average is around 6 l/100km.
Its quite pity, they could not give you the CVT.

i feel a slight hesitation when i take off. is this normal? my kid says yes. i say no. its like i hit the gas and the car takes a bit of time to follow. could be my imagination but that might be my problem. he says its just the way the new transmissions work.
how many seconds is it hesitating at? And is it only from a dead stop or does it do it other times? Like once you have started moving does it ever hesitate changing gears?
I have an automatic, and its like i press the peddle and it just seems like the car takes a second or more to jump into first gear. i am not explaining this well. it always seems as though i am hitting the gas more then i need to in order to accelerate.
Basically, you hit the gas, and it THINKS about whether to respond or not.
is there anyone out there who knows what the heck i am talking about. at first i thought it was because of the A/C - my older cars did that. but that was just an excuse. HELP - i go to dealer tomorrow!!
A friend had one that did that, new car, she almost got hit a couple times but hers was severe...it would hesitate...go...hesitate before it'd go again. No it wasn't a honda.

I also had a slight hesitation every once in awhile when pulling away from a stop sign. (base, manual) It was like the engine did not get the signal from the gas pedal to increase speed.
I just completed the "idle learn procedure" to help with the gas mileage, but have also noticed the hesitation is gone. You might want to try it out to see if it cures your problem.

CA and crudy MPG
CA uses that reformulated Water that smells like gas. Both my 97 DelSol S 5spd and Civic DX Auto get about 28mpg...until i went to OR with them then it was 33-35mpg each time.
28, CA, 20/80% got 30mpg out of a tank this week but it was 95% highway.
Now I have a lead foot, drive 80-90mph all thge time and ma usually using the padle shifters and rack it to 5500rpm to 6K when shifting.

I had a similar hesitation off the line with mine but it has since goen away. I have had the car for 33 days now and already have around 4200mi on it
The gas milage has DEFIANLTY improved by about 4 mpg.

WOW. I've been reporting 29 MPG to 31 MPG avg.. Today, I hit the half gas-tank at 175 Miles. When my light goes off, it's usually 9.5 gallons. So assuming 5 gallons for 175 miles = 35 MPG. If this is the case, then the idle learn mode may really work.
And keep in mind, I haven't been babying the pedal. I don't go crazy, but I try to allow it to accelerate smoothly without any interruptions to the pedal. I am very light on first gear, then on second gear, I give it a little more gas, and as the gears shift up, I progressively allow more gas since theres more momentum already going.

Sure... I'll go with that
Paying attention to the RPM gauge when driving shows that if you're ACCELERATING at 55 mph to... say... 60.... VERY VERY SLOWLY.... you'll be around 1000 RPM faster during your acceleration period.
On the other hand... if you downshift to 4th, rev up 1000-1500 rpm from where you were, you can be at 60, upshift to 5th, and drop those extra 1000-1500 rpm that you'd still be using if you accelerated more slowly.
I hope that makes sense...
I guess... staying in 5th and accelerating 5 mph would take probably 40 seconds or so... an average of 40,000 rmp in excess of what you should be using...
Dropping to 4th and accelerating at a faster rate.... (just for fun we'll say 20 seconds...) at 1500 RPM above standard same speed driving... you're only using 30,000 RPM more than when doing your standard driving.
10,000 RPMs less means that much less gas, right?
Down here (Laguna Beach...) with all the hills, I guess I see the car struggling more in 5th at 55.... and dropping it to 4th and getting it back up to speed then upshifting the RPM during cruise (flat speed) drops 800-1200.
Now... the 40 second and 20 second examples aren't timed... aren't actually tested...
Just a proof of concept... So to speak.
A way of showing how accelerating faster can give you better gas mileage (and helping me understand why my car's doing better now...)
