Really?

While I agree that most newer vehicles probably do hang revs a bit (like maybe for a split second) more than a vehicle built in 1980 (for example) for emissions purposes, they do it in such a way that is not as noticeable or intrusive as in the Fit. In my experience anyway. And I'm not saying that the Fit is the only car that does it, but it's the only one that I've driven where it actually impacts the drive-ability of the vehicle.

 

My 07 350z, also with TBW, does not do this. The throttle response is crisp and direct. When heal toeing, I can easily just quickly blip the throttle without problem. The RPM's also drop between very fast shifts.

In the Fit, the throttle response is delayed excessively when accelerating and deaccelerating. When trying the do a quick heal toe downshift while braking I can never get the RPMs up fast enough! Also, shifting while accelerating onto an on-ramp is like me just short shifting and never letting off the gas since the RPM's never drop before the next gear.

 

hmm does any1 have an intake and exhaust with a throttle controller? does this hang happen if u do? or has any1 got a tune yet?

 

So, not a Fit owner (former Accord owner, wow, blasphemy huh). Recently bought a Forester, and this RPM hang has been driving me crazy. It seems like there is no way to drive the way I want to: fast, smooth, and non-abusive to components. I live in Boston, and drivers here start honking and making obscene gestures at you if you don't get out of your own way in less than half a second. So, I have 3 choices:

1) drive aggressively and clutch aggressively, too -- meaning JERKY
2) clutch overly smoothly -- but feathering and slipping too much wears out the clutch faster
3) rev-match all the time -- meaning smooth and no wear, but waiting 1.5 - 2 seconds every time?

It must be an emissions issue, because when the engine hasn't entirely warmed up (thus, sensors aren't doing much, and so the ECU is in open-loop mode), this problem is non-existent and I can be smooth AND fast. What gives? I hate looking like a n00b and giving MT drivers a bad name.

This problem is made MUCH worse when driving on hills. I have to wind up the engine quite a bit higher, and slip the clutch more, because by the time the RPM time-out ends, the road speed has slowed down considerably. There are some steep hills around here. I'm 'glad' I'm not driving in San Francisco...

Anyone want to start an "angry mob"?

what's wrong with the sport AT? shifting with the paddles: does this phenomena occur here too? curious. i've got clutch knee from driving our 02 subaru outback this past week. i'm getting the sport AT.

 

how does a cvt work? i don't understand that... can anyone explain it in simple terms?

 

how stuff works - CVT transmission

 

Even driving aggressively should not be abusive to the clutch as long as you're not dumping the clutch with every shift.

I think a certain amount of feathering is okay to get the shift extra smooth, but there is a fine line between okay and too much. You don't want to rely on the clutch to smooth your shifts though, and if you do it's a sign you need more practice with your manual trans technique.

Modern synchros no longer require rev matching, but it's how I learned to drive a manual so it's habit. The throttle is super unresponsive as it is, requiring you to goose it to get the revs up there which of course only compounds the issue. I hate it, and after 14 months of owning this car it's really starting to get on my nerves. It's like Chinese water torture where it starts off okay and then slowly over time drives you mad.

Problem is, it's doubtful Honda considers it a problem and thus will not ever release any kind of TSB for it, meaning my plans of owning the car past the five year mark ain't happening.

 

I'm so happy to see another thread on this with other unhappy owners. I posted about this a little less than a year ago. I now have 20,000 miles on the car, and I still can't get used to the "rev hang". 1-2 shifts are the worst. I look like a chump when I drive this car. In my 12 years of driving, I've owned 14 motor vehicles - 13 of them had manual transmissions. It looks like I just learned to drive MT last weekend. We need a fix for this...

 

My 2007 drove me crazy when I shifted because of the rev hang thing..... I haven't noticed it since I installed the Kraft Werks supercharger.... I had completely forgotten about it doing the rev hang thing until I read this.

 

I honestly don't know what you guys are complaining about. I came from an RX-8 with a rev-happy rotary where the revs fall fast, and the stock quick shifter is like a rifle bolt. Sure, I had to get used to the Fit and looked like a retard for the first couple hundred miles. But now I don't even notice rev hang. The only thing that trips me up sometimes is the clutch engagement delay valve, but hey, I'm not delivering milk bottles... or better yet, tofu up a twisty mountain road.

 

While it probably has nothing to do with rev hang - it most definately has everything to do with driving a manual. Supposedly the Fit is equipped with a clutch delay valve, similar to what is in Civics and S2000's (AP2). The valve is a restriction that limits how fast the clutch is released. It's designed to shield the drivetrain from unexperienced drivers dumping the clutch, but it makes quick shifts and revmatch/heel toe downshifts clunky and utterly frustrating.

I drove a friends 99 Si this weekend and the clutch engagement and throttle feel makes me miss having and older Honda.

In the AP2's, one can swap the clutch delay valve out for a simple union in the clutch line, but on the Fit it is integral to the clutch master cylinder. Oh well.

 

Yes I the delay is annoying. I have also noticed the pedal popps up the smallest amount when the delay is "turned off". I do also find shifting from 1st to 2nd a pain a little bit, the syncros don't speed up enough on 2nd and I get a nice grind going into 2nd when I drive spiritly. I never noticed this in my 79 camaro 4spd, but surprisingly enough I do have a similiar issuse with my 69 beetle. Weird. So it seesm there is no Fit fix for the rev hang. Bummer.

 

I remember reading on other forums that the electronic throttle controllers are a cure for the lag thing... I also recall that I installed the one I bought from Panson at about the same time I installed the KWSC base kit on my car so it is probably why I don't have the problem.... When VW changed to the PICT 34 carburetors it really screwed them up... The little 70cc Honda Passport step through frame motorcycles were the absolute worse case of rev hang I ever experienced..

 

I'm in the same boat that I felt like a total noob getting from 1st to 2nd - usually would make the car jerk a bit during the transition and would even make the comments to any passengers that sooner or later I ought to learn to drive stick (though I've been doing so for 24 years...).

After messing around and trying different techniques, the best thing I figured is to start in 1st, and pretty much as soon as the car is moving shift to 2nd - around 5mph. If it's level or slightly downhill, I might even just start off the line in 2nd - as long as nobody is behind me to care.

Just out of boredom the other night, I started from a dead stop with my foot off the gas and ran all the way up to 5th - topped out at about 15mph on a level road.

 

I pretty much was doing the same thing as you for a long time... It was horribly embarrassing. Putting a spring on the throttle pedal and electronic throttle controller helps a lot. Enough that I don't feel like I have two left feet anyway... Somehow I have adjusted to the clutch delay valve but if I am on the throttle just a split second too soon when shifting at high RPM on boost the delay valve rears it's ugly head and the clutch slipping while there is little acceleration going on reminds me that it is still doing it's thing... Wearing something like thin soled loafers help a lot too.

 

That *&^%ing CDV is the first thing on the chopping block here.

1 month on the warranty to go..

There is no reason my race car should be smoother from 1st-2nd then my stock Fit.

This is with a ceramic sprung 6-puck disc, 2900lb pressure plate, braided SS clutch line and a chromoly flywheel attached to a super light forged rotating assembly.

 

Yeah, the rev hang does take some getting used to. I have the ETC from Panson and it DOES NOT change the rev hang...at least to any degree that I have noticed. The throttle is much more crisp (SP5), but I still have to time the clutch engagement carefully to match to ensure a smooth shift. Others have said their rev hang got better with the ETC, however, mine has not. Of course, I am not troubled by this since I have kinda gotten used to it.

Just FYI for the discussion.

 

I haven't noticed that on my Fit but it might be possible.
