that's one more problem to deal with a car that you want to tune and add more parts and tune.

ferrari's and 911 gt3's don't need those seriously, they're tuned enough from the factory, unlike the underpowered s2000.

"...don't expect too many non DBW cars in the future"

they've been saying that for years. boooooo

Yeah, but with the demand for every car to come with VSA and traction control more companies are going to move this direction.
Look at the S. They changed a car that was not originally dbw to add these functions.

I don't know about years, but are there any new hondas that aren't DBW?

How many new models from other brands? By new models I mean released within the past 2 years or so as a model, or new generation of an existing model.

And they did the same with the NSX many many years ago...

Everyone wants stability control, and it's easier to implement a more effective system with DBW. As for me, the "string from steering wheel to foot" method works just fine, hehe.

What is "drive by wire"? A plague upon mankind. An answer in search of a question. But then they probably said that about ABS for a few years, too. I know I did.

Bit by bit our cars get heavier and our driving experience more remote, in the name of refinement and sophistication and reduction in NVH. And vehicle safety which is a little harder to argue against...but then again it would be nice to have a choice. After all, how safe is a motorcycle?

which do you feel is better for traction control and stability?


A> The ECU limiting the throttle angle and smoothly reducing power to the wheels combined with abs to maintain stability? The engine and the wheels work together for stabilty.

B> the driver holding the throttle wide open, while the ecu cuts fuel and/or spark and uses abs to attempt to maintain stabilty?

IMO situation B led to an unpleasent and jerky form of traction control... Situation A makes much more sense since the throttle/power of the engine and the abs system can work toegther instead of fighting each other.

DBW is the future.

I drove an 07 with DBW and it was nice. Very smooth and transparent. Cant say i was going balls to the wall or anything but in DD it was nicely done.

If you have an '06 SI, go to the dealer and have it reprogrammed. I have an '07 and I dont have the issue.

There was a TSB for it
those dumbasses (as usual) said they understand what i'm saying and they did the reflash. but there was no change.

Your statement is not accuate. A non-DBW system can cut the the throttle even with the drivers foot planted down. It is done mechanically. Look up the service manual of an early model NSX to see how it is done. It is an ingenious design with no compromises in driver command. Bottom line with DBW is that it is cheaper. That alone is the motiviation. The drawbacks we've already discussed.

BTW, the reflashed Civic Si and even the 2007 still has some DBW Rev hang issues. Granted it is not as bad, but many owners still complain about it. Honda's positions is that this is all they can do with a reflash.

Some folks in Japan has converted their JDM Accords (US TSX) to mechanical cable throttle.
