Yeah, that was sarchasm...and well placed, I think

As far as the titles, I wanna be evolved too. In fact, I want to be "way evolved member", please. And a gold star. Wait, how many posts for a gold star and when can I have "moderator" too?
I'm just messin' with you guys...I'm curious about it too.

But I also wonder at the wisdom of rewarding high numbers of posts (see Longfury!!...he's gone ape****!) (Just ribbing you, guy...you have been very active in here and that's awsome and you have a lot of good sh to say too!!...seriously!!) But what about Quality? I mean the thought and the creativity and ... and... the FEELINGS here are so very important. Can we have an awards ceremony for the all-time great posters?

This drive by wire thing has me a bit perturbed...especially if I end up getting an STi (didn't someone say it's d-b-w?) and does anyone know how hard it is to work around? Personally, I like it when I let up on the throttle and the car stops accellerating into a snow bank.

I think the term "drive-by-wire" is being used incorrectly by many people. Drive-by-wire would pertain to a car that is entirely controlled by electronically-actuated means (think fly-by-wire in the F-16 or F-117A).
We just need to be more specific, because any or all of the control systems in a car can be "by-wire". These systems have been in development for years and we will likely see them soon in passenger vehicles.
Cars with electronic throttles are not drive-by-wire, they are throttle-by-wire.
There is also brake-by-wire, steer-by-wire, and shift-by-wire. These systems use electro-mechanical actuators to perform the functions that are usually done by directly connected mechanical or hydraulic systems. We will see them become widespread once 42V systems enter the marketplace. They will bring advantages in cost, packaging, weight, and fuel-consumption.
I'm sure we'll see new kinds of lawsuits too.

I was trying to figure out what is going on with TBW and this is what I found:
1. Everything is in program. 350Z shuts the throttle after 1 sec from applying the brakes. S4 does it after 2 sec. M3 I believe does not shut it at all.
2. There might be an advantage to TBW. If you're in low RPMs at WOT you're not getteing the best out of the engine. DBW system can keep a proper throttle position to maximize power.
3. Plenty of cars we used to dream about have TBW. M3, 911, Z06..... Would you complain about driving a 911 turbo?

Yes I would. I personnally like the older ('98 and before) porsche models alot better then the new TBW, water cooled, high tech porsches. The older ones had a more raw mechanical feel about them. Much more in commen with the race car versions. They were even faster then the ones today. I hate systems like the Porsche Stability Management and I belive that complex valve systems like the VarioCam aren't nessesary on turbo engines and only complicate what doesn't need to be complicated. Call me a simplest but I much perfer a car like the '98 turbo S to any of the porsches made today.

My 2 cents

Throttle by wire.

WOW! Yeap, WOW! Go drive a SMG M3 and you will know why throttle by wire is cool. Upshifts, keep your foot down and let the computer pull the throttle back for the up shifts, revvd matched down shifts are all throttle controled. They are like butter, and smoother/ quicker than most drivers can do. I am pretty damn quick also with the S2k. If by wire is done right with enthusiasts in mind then it can be pretty awesome. Go drive one and you will understand. I wish SMG was avail on more cars. I know about the self shifting purests, but they also need to go try it for themselves. The reason I am thinking about the M3 right now is SMG. I hope we see it make it into the EVO and STi. I mean all of the WRC teams use them. Must not be bad, right? Oh and F1 also...

Also, I think some of the new Yamaha bikes are throttle by wire. Not 100% sure though. Can't be more responsive than that.

People get nervous when computers start doing things for them, change is bad right?.... It is not like have a Microsoft Product control your right foot. You think BMW would want that type of performance/reliabilty hanging over their heads? Doubt it. Change is good, thats why we have an EVO and not some huge SUV from Mitsu.

Do you know a new BMW 745i has iDrive made by Microsoft?

iDrive by MS?

Buh? MS does the IDrive in the 745i? Are you kidding me? Really? Can you confirm this with a link or something? That makes me want a EVO even more. I can't believe that. Your messing with me right?

ROFLMAO

I never said It cant be done right. I just dont think its nessesary and it is more expensive to have in a car. Plus dont try and compare a race car transmission and a production cars because the cost of most racing transmissions will exceed what consumers are willing to spend. The sequential trannys used on race cars are way more advanced than anything used on street legal cars with the exception of the 200k plus exotics and even then I dont think there are many true race spec trannys out their.

cheers

Based on all the flack the car drew for its unconventional hind end and its iDrive system made by Microsoft ......

I am not sure why not. Everything technically superior comes from race cars. Look at the inverted shocks and ACD. A lot of that reasons that makes the S2k cool to me comes from Honda's racing background. Throttle by wire is just a step. I think we both can agree on that. And as more cars use these little steps the cheaper it becomes. Speaking of cheap, aren't all motorcycle trannys sequential. I like to think that advancements in race technology get "eventually" applied to street cars. Plus, I don't remember comparing a race car tranny to anything. I just said it would be nice to have. BMW has it, so I hope it makes it's way down into other more affordable cars. First the Ferrari, then the M3, then what, an EVO Ralliart Edition? It sounds tasty to me.

Re: Re: iDrive by MS?

WoW! No wonder it did so poorly. I have heard that it is really unintuitive and is difficult to use. Wonder why BMW chose so poorly. Good thing Microsoft doesn't know anything about racing. Keep your fingers out of my car. Yuck! Next thing you know we will have Media Player 9 in our cars. Shame on you BMW. (heh heh, that rimes)
