No, it doesn't. I use Linux.

 

We're in for a world of hurt if the '06 runs on Windows...

"Hey man, how's your s2k's new DBW?"
"I don't know."
"What the hell??? You've had the car for a week! Whaddya mean you don't know?"
"Just what I said: I don't know. Every time I push the start button the throttle stops working."
"Bloody hell, dude!!!"
"Yep. Service Pack 47 should be out next week."
"Damn. That sucks. I bet having to take the bus sucks, huh?"
"Shut up."
"Sucks, sucks, sucks..."
"I hate you."

 

You must have a Windows PC and Windows Mobile Phone.

 

Ok, I was not expecting to get this kind of response to this thread. So, I wonder how the setup on the new 2006 Yamaha motorcycles do for lag? If it has the best of both worlds with the lagless throttle response of a cable and the ECU efficiency of a DBW throttle, the dual throttle bodies could be a real solution.

 

Here is a little nugget on heel-toe with DBW...

On my S4, the ECU will not allow the throttle to open if the brake pedal is being pushed. Audi calls it a safety feature (which I suppose is true) but I believe they are also doing a little CYA from the sudden acceleration fiasco from the 80s.

The system is designed to allow heel-toe downshifting if the driver applies the brakes, waits momentarily, then hits the gas while still on the brakes. The problem is the the lag in engaging the throttle makes the whole process seem like forever. Going into turn 7 at Mid-Ohio I got it right about 1 of every 7 times.

Furthemore the throttle gets sloppy over time and needs to be recalibrated. Easy enough to do with a laptop PC. In the end, I would prefer a conventional cable/spring throttle for spirited driving.

 

I'm not sure you can use Yamaha motorcycles as a point of comparison. Having 2 throttle bodies does not address "lag" because the computer still controls how they both open and close. Any lag with one would be also evident with the other. Having 2 won't eliminate if it was there in the first place. Yamaha has traditionally used 2 fuel/air metering devices NOT to address "throttle response" but to increase the amount of fuel and air that the engine needs during certain running parameters.
This goes back to the "V-Boost" used on their V-Max bikes where 2 carbeurators fed each cylinder when the revs were up and the demands increased. "V-Boost" felt like what our "VTEC" feels like. I don't think Yamaha uses dual T.B.s to deal with throttle "lag" or response in any way. Motorcycles tend to have very short intake runners and the distance between the carb (or TB) to the valves are quite short by comparison to anything you'd find on a production car. They wouldn't need to deal with "lag" to the same extent (if at all).

 

It all depends on the programming of the DBW system -- here's a perfect example..

02 G35 w/ DBW -- def. lag. H2T was a pain b/c of the lag. Off the line driving was hard. It was generally a big PITA.

04 350Z w/ DBW -- no noticable lag. H2T was perfect. Off the line driving was easy. Seemed like it was a cable to be honest...

The difference? Programming -- I think they purposely engineer that lag into the car, I'm not sure why though. Most racing cars today that use any form of Electronic Assists use DBW (F1, WRC) so...I'm sure DBW can be just as good as cable...(as far as throttle response goes)

 

This is the ONLY thing that concerns me with the DBW component....

I just don't see how it can keep up with rev-matching and heel toe throttle inputs.

I gotta get my ass out to test drive.

 

I don't think thats what he meant. Here is another post from Jeff on vtec.net.

While in LA last week, I had the chance to very briefly drive an '06 S2000.

By very briefly, I mean like maybe 5 miles. Anyhow, I'm very happy to report that the conversion to DBW seems to have had no immediately noticeable impact on throttle response. In other words, the dreaded lag isn't there. So now there are two Hondas with DBW that don't exhibit the infuriating lag - the S2000 and NSX. I just wish other DBW Hondas could be so good.

It was nighttime when I drove the car (it was the new blue color) so it was hard to really see much of the interior changes. The stereo sounded ok, though the new rollbar mounted speakers are partially blocked by the new solid headrests. I was hoping to have another look at the car on Saturday during the daytime but it didn't work out.

He's done some articles and projects with the dbw lag so I'm guessing he knows what to look for with dbw lag.

 

I'm not saying it's impossible, just saying it seems a lot less likely.

My cell phone has never crashed though.
