Making fancy youtube race videos... duh

Maintenanceman

I checked the oil level as soon as somebody mentioned it, exactly on the top mark. So, no oil missing.

i like to drive fast sometimes... it's fun to do a 3rd gear pull on the freeway....

too bad this car isn't faster..it would be even more fun.

so is this just "normal" for our cars???

My car does it too. And my car is pretty quick, esepcially 3rd gear. But I have a few goodies to help

RL.

Just tried this today and to my amazement my car does the same damn thing! Wtf design flaw for sure!

Maintenanceman

Annoying feature, i want to get rid of it.

Matt W

Did we ever find a solution to this? Mine also does the same damn thing, this is probably my biggest disappointment with the RL, takes 1-2 seconds off before it will actually get past this hesitation so I can shift to 4th and keep plowing on.

BTW LOVE THE TAGS ON THIS THREAD

Maintenanceman

I think no.
Maybe it is some bug in the software because it doesnt do it when using "auto mode", only when using those flaps.

I'm not sure, short of reprogramming the shift points how it could be fixed.

I would also think its there for a reason, well, a reason other than "because not racecar"

oo7spy

Hasn't it been determined that not all RLs do this?

I would love to try it out, but I don't go to secluded straight-aways alone very often and am not trying it on a freeway since I can't take defensive driving for another 7 months.

I think I saw mine doing it, but honestly I didnt really care.

oo7spy

When I hit VTEC, it is in 1st and 2nd. It is not very often that I need to hit 90 in a hurry, and if I do, it is probably a better option to slow down than speed up.

oo7spy

It doesn't always happen with all RLs. Even BDogg was able to replicate once and not again. What I find most interesting is that the acceleration never stalls. The speedometer is always going up even as the tachometer stalls. I'm not sure why anyone is concerned about a dip in RPMs if they are still accelerating.

Yea maybe its there to keep the RL in a sweet spot in the power band

I was time testing my new intake compared to OEM and saw this..
I tested 4th gear pull from 60kmh to 200kmh.. didn't notice this with my OEM intake but noticed it with the intake..
I made a video.. goes to steady from 25000 to 3400rpm than falls to 3000 than keeps climbing again and no stall .. 4th gear in sport..
Funny I didn't see it happen in 3rd just 4th

stefce

stefce

here is 3rd gear pull

oo7spy

Proof again that it doesn't always happen...

stefce

See the speedometer.. even when the rpm fall it still moves with same pace.. like no pulling power is taken away.. its from 110-120kmh

stefce

Well it can only be one thing.. and has nothing to do with the engine..
Its a issue connected with the torque converter in the transmission.. I would like to see if this sort of thing happen in the 6 so transmission..
They say they put a better and more robust torque converter in it that can handle more power..
That's why this happens in some cars and not in other and in different gears..

Matt W

His video clearly shows it happening at about 4.5k RPM, I would bet that this happens on almost the majority of all RL's.

I would have to see a video of BDogg doing a 3rd gear pull to believe that his RL doesn't do it, maybe he isn't noticing it, it only last 1-2 seconds and it can be hard to keep your eyes on the gauge while traveling at that speed.

ichi d

if listen to your car, it does not hesitate only the gauge does.

ichi d

you are suppose to leave it in D and give it wot. thats when you will notice it in 3rd gear. btw nice cdn RL. must be 09+?

oo7spy

But that isn't the same symptom. Numerous people have explicitly stated that it happens in third gear right after crossing the VTEC threshold which is at 4950 RPM.

Chas2 and BDogg are very competent in posting their experiences. If they say their car didn't do it, then I believe them.

Matt W

I can hear my car hesitate, you can clearly hear his car hesitate in the video at 12 seconds.

He is in third gear, obviously I can't get an accurate reading on the guage from this video but re-watching it it looks more like 5k than 4.5k rpm. I have seen at least 5 videos showing the same thing. When somebody can show me a video where there is no hesitation in 3rd gear at that RPM I will believe that this doesn't happen to all RL's. Until then all the evidence shows that this is normal behavior for RL's except for a few people who say it doesn't but haven't shown any proof. One person even said he test drove another RL at the dealer and it did the same thing, there are multiple threads on this issue.

oo7spy

Maybe you missed this post? I completely agree it is normal, repeatable, and frequent. I just know it is not the rule; there are too many exceptions. I would bet some RLs could do it in auto mode, unlike the testimonies we've seen here. The problem is you are asking for a sample of data that requires typically unsafe conditions to occur. Asking me to throw my camcorder on the steering wheel is putting more risk to a rare event. By the same argument, show me it happen 10 times in a row and I will believe it happens to all RLs.

The common theme among people who have seen it not happen is cold weather. Stefce, what were the temperature differences between your first run when it happened and your last when it didn't?

Maintenanceman

Mine does it every time if i am using "manual" mode (only third gear).
Doesnt do it at auto mode but then if i floor it it wont go near the redline, shifts so far from the redline that rpm`s drop much under the vtec point.
I can hear the rpm`s drop but speedo seems to be climbing...

stefce

I filmed the 4gear run 3 times and happens on all runs the rpm fall ..OEM intake was tested on 16c and this video is at 20c
I filmed all runs and happens on all ..I can post them if you like
What I want to see if this happens on the 6sp auto.. can't somebody that has a 6sp RL chime in? Or at least someone else try it on a 6sp dealers car or so?
Does this happen on a TL sh-awd?

oo7spy

So, I had some time on open highway today away from the city, the moto-cops, and their lasers. My car definitely does it at 5600 RPM, but it depends on the circumstance. I first started in 5th going ~65, dropping down to third, and flooring it. The RPMs climes smooth to 6k, but I started almost in VTEC because of my speed. I did it a few times and couldn't get it to happen. Then I had the chance to go from 2nd to 3rd (much lower RPM) and it happened very obviously. The RPMs hit 5600, stalled, dropped to 5500, and then started to climb again. It was very noticeable. From there, I did another drop from 5th and WOT. I got a similar response, but less drop and a faster return to climbing. I tried it once more at speed but pushed the throttle harder, and the tach only stalled. It never dipped before continuing to climb.

I think it is a very common occurrence when coming out of 2nd and trying to red line in 3rd, but if you are in 4th and need to drop down, you may or may not see it depending on how aggressive you are with the throttle.

stefce

The obvious question is if someone reported this to a dealer and got an answer or at least tried to get an answer. Also we need test from a 6sp tranny.. I can bet that this doesn't happen to it.

oo7spy

It has been reported to the dealer. Check the thread linked in the first page. They don't have an answer. (Not that dealers know what they are talking about anyway. )

I did have another chance after my last post dropping down from 5th again, and this time it happened at 5400 RPM. I did it twice and it is much faster of a dip and recovery at speed.

It is kinda weird in that it is almost acting like their is a turbo kicking in. I know their isn't, but the decrease in RPMs and constant power seems like the engine is getting more air than just before it happens. I agree it is weird, but I still stand by my statement that since you are not losing power/acceleration, it shouldn't really be considered an "issue".

oo7spy

Lockup doesn't happen until you have reached a reasonable equilibrium between shaft speed and fly wheel speed. Namely, the RL will not lock the TC unless you are in 5th and cruising. It definitely isn't locked while accelerating.

oo7spy

Don't know why Türk's video didn't embed.

@oo7spy

So, do you agree with me?

oo7spy

I am not sure I understand your hypothesis. Can you restate it?

The drag at 90 mph/150 kmph is so great that even a slight decrease in throttle will immediately stop acceleration. I can agree to a point that at low RPMs and low speed, acceleration will not stop immediately. However, you gained 5 kmph between the time the lag started at 5800 rpms, dipped to 5500, and got back up to 5800 rpms. Also, your speedometer movement never changed. The acceleration during the dip was just as quick as before and after.

getakey

there can be no acceleration without a force applied, right?

oo7spy

You can't even maintain speed with drag without force.
