Also, when I push the clutch down, the rev hangs for about .7s - 1.2s, somewhere in that range... should I be getting my **** flashed too? lol it IS an 08.. so, I don't know if it is needed or not.

No, i dont think you need a reflash. What we experience now is suppose to be the new and imrpoved unfortunately. The rev hang isnt so bad, except i guess it can wear the clutch a little more if shifting fast. But the freaking transmission is making me want to trade this in for a GTI next year.

I wonder if these transmission problems are common. Like with the RSX typeS.

I have mentioned the rev hang to my dealer when I first bought my SI and they said that's how it is. There's nothing they can do except wait for an update from HOA. As for the buckling when it's cold, there has been no update or reflash for that. You just have to let the idle drop atleast to 1.5k and apply the gas smoothly. It's ideal for 3 bars of temp, but that can take 2-3 minutes in the winter.

I can avoid the buckling feeling leaving for work without a full warm up, but it's impossible when going home. The reason is because there are alot of bumps in the parking lot of my job and it shifts my foot when i go over them, causing the car to buck even in third gear.

Roper · 12-11-2008, 03:36 PM

I agree. I expect we're just going to have to live with these quirks. I've gotten used to both; I don't like them, but I'm done worrying about it.

si_pinoy · 12-26-2008, 04:51 AM

my car falls under this bulletin... what should i do next once i told them that my car rev hangs and having trouble shifting from 1-->2-->3 and they refuse to fix it?

seattlecivic · 12-26-2008, 06:02 AM

My car takes over 5 minutes to warm up when I get off work and it's 34 degrees outside... It only buckles when it's cold... so I just warm up the engine. Even trying to to be gentle on the gas doesn't make the buckling go away... so you just have to be patient with it. It's not good to drive on a cold engine anyways..

As for rev hang problems... or the 3rd gear problem... i've yet to experience it. An 08 Fa5, driven for over a year now.

i think im out of luck coz i have three problems:

1. Notchy / Hard shifting
2. Popping noise off my front suspension during maneuvers
3. Rev hang that needs reflash

i really love my FG2, but im frustrated about this issues.

8.2kredline · 01-03-2009, 01:33 AM

Same behavior in my 08 SI too but I can live with it and it does make low rpm downshifts somewhat smoother. Hondata apparently knows how to fix this (ECU reflash). Why can't Honda get it right? Too bad Hondata won't do a low cost reflash that just corrects this issue.

bry · 01-03-2009, 01:41 PM

i have an 09' si sedan and i'm experiencing some rev hang problems. don't you think honda would've fixed this problem? haha

fryrice · 01-09-2009, 05:24 PM

anyone else have a 08 fa5? i do notice the bucking in the early cold morning but i think its because the car is not warmed up first...and as for the rev hang i do notice it on mine, but not experienced enough to really tell if it is a rev hang or not.

i would be in 3rd about 3500k and i press the clutch all the way down while leaving the gear in place (not neutral) and it is suppose to drop?

There was a discussion about this somewhere... It seems to be the norm for our cars... or any K-series motors? The best thing to do is just let it warm up a bit.. I usually wait for two little bars or 1.5 idle on the tach.

OrdnanceMarine · 01-10-2009, 12:52 AM

Mine stops the bucking when the coolant temp reads ~110-120F on my ScanGaugeII. I'm very gentle on my car until it's at least up to 150 and still pretty gentle on it until I see upper 180's for a little while.

To be fair to the Si, my 2005 CR-V has DBW and you can notice some bucking under the same circumstances even through the automatic transmission's torque converter which is VERY spongy compared to our directly connected manual transmission.

This seems to be a problem with other K series DBW Hondas and not just our Si.

As far as rev hang goes, I noticed it a little bit when I first bought the car but I can't seem to see it anymore. My bet is that I've just gotten used to the way it works. One thing I do love about the throttle setup is that blipping the throttle for a double clutch downshift is so easy in this car compared to others I've driven.

After owning two 8ths, I agree totally. After my early build 06 got the rev hang reflash, I pretty much forgot about the DBW. And blipping is easier because you can just stab it and the flexibility of the engine takes care of the rest... Love these cars....

As for the tranny, no issues if the car has had a chance to really warm up...
This goes for both my 06 & 08. My 06 failed to give me gears more often than the 08 but I always attributed this to cold temps, bad clutching or poor seating position...

TW_FA5_SI · 01-11-2009, 04:59 AM

sorrie guys, but what do you all mean by buckling?

well anywayz i know it is okay under 3k rpm, but it gets kinda slower upto 4k rpm...and then the nasty rev hang around 4.5k-5.5k rpm.... i showed this to my brother and he was like wtf???? you dont have reflash to fix this??? lol oh btw he owns a ITR and his is AWESOME

fryrice · 01-12-2009, 10:45 AM

i believe bucking is when the car does not have enough rpm and it is about to stall by having a chug chug motion.

It's a little like that but does it at all RPMs. It kind of feels like the throttle is opening/closing over and over again even though your foot is steady on the gas pedal. I have no idea if it does it above 3000 RPM or so since I don't take it that high when the engine is so cold and the throttle so touchy.

lilzinger19 · 01-13-2009, 08:32 PM

as weird as it sounds, i installed a K&N drop in air filter lastnight (19200 miles on stock paper filter) and it seemed to dramatically help the bucking when cold this morning. it was 26°F this morning on my way to work. i will try it through the rest of the week and update you guys. supposed to be a high of 6°F on friday.

lilzinger19 · 01-13-2009, 08:34 PM

by the way, i have a 2007 civic si sedan. I never had a reflash, it was supposedly done by the factory.

that could be it... i put the drop-in in my 06 before 500 miles... same with my 08, it was installed in the dealer parking lot... and now I have a modified stock air box and M&M scoop and the breathing improvement dramatically smooths out the throttle/clutch effort because of engine never chokes for an intake charge. Even without a proven HP benefit it makes the car much more fun...

OrdnanceMarine · 01-14-2009, 05:38 PM

Maybe I'll notice a difference when I install my AEM CAI this weekend.
