DBW Throttle could be better than a Cable

I hate it with my Cooper S and M3. Don't even think about coming out of a turn hard cause the DBW won't let you. I notice for both cars that when ever the steering wheel is not straight, the ecu would alway interfer.

Of course one could turn the "DSC" or Traction Control off, but why buy something to turn it off.

I love my cable 04' S2k.

Having such a feature is to make the car more "idiot proof" in day to day, mundane driving scenarios, which will most likely be 95% of the time for most owners. Being able to turn it off would be for track duty and times of more exuberant driving.
For example, the S2000's cruise control is always ON and ready to use. You can also turn it OFF, but how many of us actually do it?

I have to turn it on in my 04.

I drove a MB with DBW ad didn't like it. Not sure where the problem was, but throttle tip in was very abrupt, you'd go from not enough to too much when starting out - made parking a nervous event.

Even if the DBW "maximizes performance" by adjusting the throttle setting in response to gas pedal pressure and ECU data, does that mean that the performance is "maximized" for horsepower/torque, fuel economy, emissions or something else. Although maximizing each characteristic would have some desirable effects, settings that minimize emissions or maximize fuel economy may do so at the detriment of maximum horsepower/torque. Conversely, settings that maximize horsepower will likely reduce fuel economy and increase emissions. It seems that it will be important to know exactly how the ECU and throttle pressure interact and, if the DBW-system does change the throttle setting to "maximize performance," to determine exactly what performance characteristic is maximized.

Speculation: Although it may mean nothing because of the lack of precision, I believe that the fuel economy for the 06 listed in the sales booklet is identical to the 04/05 and am unaware of any claims by Honda that the DBW-system will increase fuel economy or horsepower. Doesn't the 06 S2K meet a lower emissions standard than the 04/05? How did honda do this with the same engine? OMG, could this be a hint that the DBW-system minimizes emissions, possibly, at the expense of performance? That might make the tree-huggers happy but not the performance drivers.

You won't be able to turn-off the DBW throttle. It's the only way the throttle will be connected to your foot in the 06.

He was talking about the Stability Assist, not DBW. You can turn off that ONE negative aspect of the DBW...while still experiencing the lag that MAY NOT EVEN BE THERE!

In the words of Bill Clinton, "that all depends upon what the definition of it is" ..., but you're probably correct in spite of the title of the thread.

I don't think DBW or stability control is bad/disadvantages. I drove my friends new bmw 330 and 325 (both have DBW, traction control, and one has active steering), and the car was so easy to drive with DBW working with stability system. I would take a freeway off-ramp at pretty decent speed and the DBW and stability control system would do the work for me... and with active steering it even corrects my steering a bit to further enhance stability of the car... I can't say it is more fun than my s2000, but it was easier to drive. the car felt very stable throughout the turn and I didn't really have to "try" to control my throttle or steering too much. for those people who wants to have fun, but don't have good hand eye foot corrdination will benefit and enjoy the new technology...

but I did notice a "slight" lag under full throttle
