DBW is what it sounds like. A wire runs from your accelerator to a motor on the throttle body instead of a cable. There is a motor there that opens/closes the throttle. There is a delay with the motor unlike the traditional cable. Personally I think it is one of those things that is better left alone. Just something else to have to replace.

FWIW, in most DBW systems the delay is on purpose to "smooth" out small changes in throttle application. This is why they say in the TL commercial that the car "learns" how you drive and customizes itself to how you get on the throttle. In theory, it should give someone who is aggressive, more throttle sooner than someone who is always tapping on the gas.

would this apply to the S2k too, where it learns your driving style?

Why not just make the darn thing do precisely what the driver asks, just like the direct cable control on the previous models do? If the driver screws up and the stability control has to take over for a second or two, so be it. Otherwise the DBW system should just do what it's told, nothing more and nothing less.

Well I'm not disagreeing with you on this either, I wish they'd just leave it off the S2000. I do know that the system could be so fast that it would overreact to driver inputs if allowed to. They (Honda) says this results in jerky driving. It's similar to how they slowed down the speedometer display so it's not always changing between 58, 59, 57, 58 as the speed of the car fluctuates.
Technically isn't a regular throttle cable not eitirely linear either? On the throttle body the cable wraps around a cam shaped guide. This must modify the opening of the throttle plate. Maybe xviper knows for sure?

i realize everything it seems like is getting away from being mechanical and more so electronic....however i dont see where the old fashion way has its faults.i dont find it to be un-smooth or jerky personally.i like the cable,its one less thing to go wrong i guess.but im gonna go test drive a new s2k or even a new civic if i need to and ill report back with my review of it
