Hello,

I have an 2007 Acura TL. I noticed the throttle response isn't as quick as other cars such as the TSX. When i press on the gas slightly harder than normal, I noticed that the car shifts its weight back a little then it goes off forward. I think it's because of the throttle response is bad.

What do you guys think?

 

We all know the low end torque isn't impressive but I wouldn't say it's better than a TSX..

 

Where in his post do you see him talking about low end torque? He specifically stated that he notices throttle "lag" when he steps on it.

I too have noticed this in my 08 base. I drove a 2010/2011 Honda Accord Crosstour V6 today and was blipping the throttle slightly and to my surprise that car has a very good throttle response. The car immediately sped up when blipping the throttle.

When I do the exact same thing in my TL, all it does is rev the RPMs up but the car doesn't actually accelerate at all. At low speeds I can literally quickly mash the pedal to the floor and let go and the car only revs up and doesn't even pick-up speed. In the Accord Crosstour V6 however if I did the same thing, the car would pick up speed before I could even let my foot off the pedal.

Throttle response in the TL is pretty laggy. I don't know if it has to do with the DBW system or not, but I think the Accord Crosstour is also DBW..

 

how many miles on the car?

mabey it needs a tune up?

the vtec motors make power at higher rpms, if you have an auto it will only make the response that much slower.

my auto is the same, however, when i floor it and it hits vtec, the car is pretty quick.

 

Yes this is exactly what I mean. I step on the gas and the RPM revs up high but the car doesn't speed up right away. It "lags". Is there any way of making the response faster?

 

There is a huge thread on how to reset the ECU which many say gives the car better response and throttle feel.

 

I drive a 2008 Honda Accord 6MT and I have seen and heard of the lag issue with some of the Accords and they use the Ithrottle to make the response better, or you can set it so the response is slower for better mpgs.

I am not sure if you could use the same thing on the TL or not..

 

To improve this response, take out the delay valve retainer on the slave cylinder if you have a 6 speed manual. This will not cure the DBW lag, but will cure some clutch lag. But most importantly if 6 speed or automatic, you have model year 07-08, get yourself Hondata Flashpro. You'll get no more DBW lag.

 

What?

Isn't this simply just the nature of drive-by-wire?

 

Lol, I don't know, cause I don't know what/how automatic feels.

 

Auto, manual, we're all drive-by-wire.

I knew a guy once that traded in his CBP Type-S because he couldn't stand the throttle in our cars.

Bet he'd sing a different tune after doing a retro cable job...

 

honestly; our drive by wire isnt that bad.

I get instant throttle.

 

OP is comparing two DIFFERENT vehicles.
A) a small and nimble car
B) a heavy car

we have no clue how his car is performing unless he provides more details.

 

No, it's really not. We are talking a very very small delay. But, there is a very very small delay. People who are used to cable throttles don't like it.

It's because the car is pretty heavy, it's not *that* noticeable... lol.

 

I believe there is a 3G or two around here who have done the cable conversation. Jumping from one to the other I bet you would be able to tell a difference.

Splitting peas though we are talking fractions of a second.

 

I also remember, at one point in time, that there was some kind of module you could buy that increased voltages or something that removed or shortened the DBW delay. Not sure if that was one of those eBay scams or what though.

 

I know people weren't happy about it when they switched (rsx had cable and the new si had DBW IIRC). I test drove both and didn't feel like there was a huge difference in lag.

Maybe one of those idle relearn processes to reset ECU would help?

 

Not unless you drove an SI with Flashpro, lol. Other than stock, there's a difference.

 

Do any of you guys feel the car shifting back a slighg bit before it zooms off when you hit the gas pedal? What is the cause of this?

 

Inertia

 

That makes zero cents. You describe a delay but the symptom is acceleration...something don't jive

 

I am talking about the weight of the car shifts back a slight bit just before it accelerates up. Anything i can do to prevent the weight shifting?

 

I guess I don't understand. You're describing the feeling OF the car accelerating when you say the car dips back. Maybe it's the vtec kicking in that you're not used to?

 

Have someone sit in your passenger seat and video tape it.

 

OMFG i busted out laughing.

OP, what you are describing is natural physics at work.

 

Well the car will squat if you mash it...
The engine will rock...

For instance the ETD helped that feeling on my car. I'm sure I've got a poor rear mount too. Probably the others as well after 90k.

Get in your car next time, leave it in N, and mash it. Do you get that little "rock" feeling without even moving?

 

Do you put premium fuel or regular 87 fuel?

Mileage on car and last spark plug change/tune up?

Get your car into the hospital ( dealer/shop ) and get her checked out if you feel that it's not supposed to be as what you say it is.

 

this thread is just so full of win.......

 

What "rock" feeling do you mean? Can you describe it. Sorry I am new to this.

 

As you can tell from your 3 threads on the same subject; people have different views on what is going on with your TL.

only; we have no fucking clue on what the fuck is going on with your TL.

 

Is this for real?


Have solid steel welded around your rear springs.

 

 

unsubscribed...

 

does the type S have better throttle response? I think it does...

 

Buy a stiffer suspension

If money is no object buy an advanced electronic suspension system like that of the GT-R or Ferrari.

 

when I brake the car rocks forward. maybe if you try a combination of the two you could keep it perfectly level

 

I am new here. I have an 06 base that has never had anything done outside of my dealer's shop. (yes I am broke). But they always tell me they "applied all the electronic upgrades" whatever that means. My little gal jumps when I touch the throttle. No hesitation. No lag. Maybe they did something to her at the dealer that prevents this? Just a thought. 99,500 great miles. BTW it costs me to take her in but when the dashboard cracked over the passenger air bag, they replaced it free. Sorry. Did not mean to derail the thread. and I get a free loaner and I get a free detail. So for a non-mechanical person like me it's the way I have to go. (just trying to explain and head off the enviable comments about dealer repairs). :-)

 

^great to hear that your TL is awesome and that your Dealers are treating you welL!

 

Wish I knew why so many people still think DBW systems have "lag" most cars these days are DBW and I notice no lag whatsoever. Infact during some diagnosing on a previous Type S I had the air cleaner box and tube off and watched the throttle blade under the hood as I played with the throttle. It is dead on exact to what your foot is doing. If there is a delay in acceleration it has to do with some other system and certainly not the throttle. For what it's worth, the 6mt TL definitely feels more responsive than the auto, but I would have thought that's obvious when dealing with an auto trans and torque converter.
