I've never noticed that effect unless the engine is operating a very low RPM. The only delay I've noticed would be when using the clutch. Even then it's not a bad thing in day to day driving. Might smooth out the shift a bit. It might lack the linearity, but it is still very easy to modulate small throttle changes.

Again, you are all complaining about the CDV, same as the other guy LagunaS2k or whatever.

CDV != DBW, VSA or anything related.

In fact, the CDV (clutch delay valve) has been in use since 2004.

If that clutch delay annoys you, simply perform the CDV removal mod.

\My only beef with the DBW system, is about the only beef I have with my 06 S2k - When I dip into the throttle when taking off from a light, or when applying power again, after shifting, the damn system applies barely any power at first, and then kicks in. Kind of like some of the other "on-off" comments I often here about DBW. It lacks the lineararity of a cable system. Can any 06 owners corroborate this, or is it all in my head?

My '06 does exactly the same thing, and this has absolutely nothing to do with the CDV. I had the Honda tech ride with me and he clearly saw the stumble. Then, they did nothing and listed it on the warranty ticket as "could not reproduce problem." When I challenged the service manager, he then claimed that Honda considers it a "known issue" related to fuel supply???

Whether it is a DBW problem or not, it appears that Honda has no intention of addressing it.

If I have to drive in the ran I turn the VSA on. Asides from that it's pretty much off.. I <3 my VSA.

As for the DBW. The S2k is my 1st DBW car and I don't feel any difference what so ever..

Does turning the A/C off help this? This helps with the initial lag, otherwise, I've noticed it too, but assumed it was "lack of low end torque" I have to wait until I get the car up to at least 3000rpm before I really take off.

For shifts though, no symptom, if I want power after the shift, I wait until the redline. In the next gear, I'm in VTEC, with power to spare. If you want power from this car, you gotta keep it above 6000rpms. Hard to do starting at a traffic light, but plenty easy in upshifts.
