I did a search already and still dont understand, it would be nice to have it put in a lamens term for me. If i were to consider of changing my DBW to throttle cable what steps are necessary, and or would you even recommend doing this modification. I know you must get RSX cable and something to do with the ECU or even a K pro. And last question do Euro R's have DBW??

Thanks

and if your going to hate and be expletive if i made a repost please dont throw fire at me i will cancel if you guys wish.

 

Why do you want to get rid of your DBW?

It's possible to do, but you'll lose a lot of features like cruise control, HVAC, gauges, traction control, etc.

 

This is my understanding of DBW, someone corrects me if I am wrong --

With the old-fashioned throttle cable, the accelerator pedal is connected to the throttle or fuel injectors in the engine directly, hence, the response is direct. You push more on the accelerator pedal, more fuel is burned in the engine and RPM increases. With DWB, the accelerator pedal is hooked up to a computer or a microchip, which interpretates the action or the traveling of the pedal. The computer then controls the throttle in the engine.

 

The non-DBW TB uses a direct cable links to the accelerator pedal. The throttle plate movement is proportion to the gas pedal input (providing the cable is properly adjusted). It's normally a few % open during idle and close to ~98 or so during WOT. The throttle plate connects to a TPS (throttle position sensor) which provides feedback to the ECU along with other sensor inputs for fuel management. There is a separate cruise control actuator for the non-DBW TB.

The DBW TB on the TSX also has a direct cable linking to the gas pedal. However, this cable connects to a Accelerator Position Sensor on the firewall. This sensor sends the input to a controller which sends the drive signals to the DBW TB actuator to move the throttle plate. The drive motor is on the TB housing. There is no separate cruise control actuator for the TSX. It's done via the DBW TB. Other sensor inputs for support traction control also affects how the DBW TB moves the throttle plate.

 

Thanks you guys I dont think im gonna go through with it haha. I heard if i changed I could run K Pro but reflash is fine.

 

just wondering why some guy on Honda-tech told me u can run K Pro, i thought u couldn't because of DBW

 

did all tsx model come with DBW?

 

 

FYI, EuroR didn't have DBW. And you can change to a k20a throttle body, convert to cabled throttle and gain the ability to use the K-pro. But you will lose cruise control and maybe VSA.

 

^^ Oh, and you will most probably need an aftermarket instrument cluster as well.

 

Honda's DBW is like Ford's automatic transmission. Both are equally shit compared to the good stuff.

 

keep the dbw......i personally liked the newer cars cause of this

 

If Acura can refine the DBW system to fix the lag problem, then fine. As it is now, it can be pretty annoying.

 

what you mean, can be?!

It is annoying!

 

With the cold weather and my recent intake mod, I've been testing the throttle a bit more than usual, and thinking about the messages about the DBW lag that I've seen in the past. I'm not noticing much of a lag, or at least not one enough to annoy me.

What kind of lag are we talking about? I tried searching, but I can't seem to find anyone willing to commit to a time.

Is it .1"? .2"? It can't possibly be more than that; not in my TSX, anyway. My guess is .1 at the most.

 

It's not the amount of time that matters. Almost all cars(DBW or not) have a small lag. It's the magnitude of the hesitation that is absolutely pathetic on our TSXs. If it was just a small hesitation it wouldn't matter if it even lasted a whole second. The hesitation brings the engine to an almost complete halt making the driver's head almost bang into the steering wheel.

I don't understand how some people don't notice this. Anyone who is used to shifting gears in a normal fashion should be able to notice this annoying crap and complain about it.

Today I unwillingly ended up in the right-lane of a 2 lane street behind a red-light. There was a truck on the other side of the intersection blocking my lane. This meant that upon the light turning green I had to find a way to get into the left lane. Normally this would be an easy task even if I had a 106HP Civic, let alone a 6MT TSX. But no! The driver to my left decides to be a dick and doesn't want to let me in. I either had to stop in the middle of the intersection or floor it. I chose the latter forgetting how my lovely DBW would f*** me over and decide that it's best to halt the injectors while I'm trying to apply full throttle.

Before this incident I never thought of the DBW as a safety issue. I decided to not think about it and try to get used to it, but not anymore. It almost got me into an accident.

I'm hoping enough people finally come to their senses and complain about this while my 06 is still under warranty so a recall is generated and Honda/Acura fixes this major screw-up before too late.

 

The TSX's DBW cuts fuel to the injectors upon full throttle? I don't understand. When I floor it, my car just goes. I often drive hard to 7,300ish through the gears, and have never encountered DBW problems with my '06 6-speed TSX. Maybe newer TSXs have been updated?

 

That's what I'm saying! I don't understand the "bang the head against the steering wheel" comment at all. The time it cuts fuel for me is when the mediocre tires start to slip -- that's the VSA, not the DBW.

Mine's a late '05.

I can shift quickly too. No short-shifter needed here.

Maybe we don't notice because it doesn't happen? There must be something else going on.... Maybe attend a TSX get-together, and ride along with someone else who claims to not have the problem? At least to try to see that it's not all TSXs... Then take it back to Acura and demand that they fix it.

If you floored it from a dead stop, I'd say that it was the VSA kicking in. But if the street was OK and you were already moving at part throttle, then floor it, then I don't know why it would all of a sudden kill the engine. The most I would expect is that it just would take time as it builds up some steam...

I mean, if you're side-by-side even with a slower car that floors it, you're going to need a lot of room to get in front of it, if they want to really put the screws to you, so I think you're describing a tough situation anyway.
