Launch Control, where is it and what I have learned.......

Re: Where did you get the notion...... (cb1111)

From Car and Driver:
For all-out acceleration, DSG has a launch-control feature in which the engine holds at 3000 rpm and, when the brake pedal is released, takes off with a tuned amount of clutch slip and wheelspin. Using this method, we managed a 6.0-second 0-to-60-mph sprint and a 14.7-second quarter-mile at 95 mph, even though we thought the computer allowed too much wheelspin.

I think I remember that the first M3 with automated manual tranny had an amount of launches you could do until the computer would not allow this anymore since it abused the clutch too much, I don't know if you could get the dealer to reset it or anything, but just bringing this as what might be the real concern.

I definitely know what you're talking about here - Launch Control used to be considered an "Easter Egg" in the bimmers of yore. From what I remember it would only let you drop the clutch like 10 or 20 times and that was all you got

...LC limits the amount of power to the rear wheels to control wheelspin....
If we can't control wheelspin at 1500/1800 rpm, what good is 3000rpm?
I can control wheelspin with my right foot - what else does LC do?
If it does nothing then we're just getting all upset about nothing.....

The Launch control is not a separate computer it is software already in the DSG, it is not a different DSG tranny or anything to the likes. It is just software.
As posted above, the Launch Control DOES control wheel spin, it feathers the clutch so you get going as fast as possible with a controlled wheels spin.
that is why they get better numbers using the LC, the only thing that I didn't like about is is that after you let go ir took a bit to actually launch, a little bit of time but noticeable.

I doesn't do anything else, just a better job than you could ever do, just like the DSG changes gears faster than you could ever do. Or anybody could, this is not a flame, but if you don't like a computer doing a better job at something then why go DSG at all, just get the manual or ask for VW to keep a torque converter automatic as an option and that's it.
It is not worth getting all upset about, I'm definetly not getting upset, but just think that this option should be turned on by VW, if it's already there why not use it, hey if it sells one more GTI than turning it off then so be it, bring more people to the brand.

The funny part is that they read the many posts right here on Vortex by members saying things like "What, are they crazy, kids will be killing themselves and VW will get sued", and that got them thinking again......

They read the vortex for guidance?
WTF, is VWoA being steered by idiots!?!?

I've been told otherwise, but let's hope it's just an ECU flash of sorts.
I'd like to have it just so I can play around with it.

Yes this suggestion is ludicrous...

.........you are assuming, of course, that it is there. Popular consensus on this board, however, is that it requires swapping out the TCU.
I agree, it might be a nice thing to have, but to listen to some of the folks it is as if VW decided to deliver the car with only three wheels....

But none of the cars are coming with it at this point. It is a misconception that is is a week 50 change, the only things that Brian says he heard (IIRC) is the ride height drop and the headlight washers. The LC has always been week 22.....
the system is on hold, and the decision of whether it gets included has not yet been reached. The funny part is that they read the many posts right here on Vortex by members saying things like "What, are they crazy, kids will be killing themselves and VW will get sued", and that got them thinking again......


so that means current 07 models have LC but they are not activated
or unlocked?
and then can current 07 models get their LC unlocked if VW decide to allow that feature in U.S?

Well, they have changed the origin of manufacture from Germany to Japan for the DSGs for 07, so maybe something is different?

06 transmissions were manufactured in both countries as far as I know.

And that's why these ads disappeared, I guess....
And I forgot to add, I was told that when an if LC gets in the cars, it WILL appear on the window sticker, as the window sticker is the only legal provider of equipment in the car you buy.


I got an ad in the July 2007 issue of Road & Track.
But I think they ship those in like May... so maybe not.

But the real reason they disappeared is because people probably stuck the stickers in places they didn't need to be stuck.

nvm i'm tired.

Maybe the problem is not so much about the lawsuits from people getting hurt but from people abusing the option and then having clutch problems and warranty claim

I think that comment has a lot of validity IMO .
LC is not even mentioned in the GTI handbook here as if it doesn't exist & it wasn't promoted IIRC . unlike the US ad. in this thread.

I have LC in my car. It doesnt feather clutch and it doesnt control wheelspin. All it does, is allows for increased RPM's for quicker takeoff. Clutch bites in pretty hard when you release the brake. And you still need to use your left foot to control the throttle. WOT results in a burnout. This is in 2006 model car, unless they have changed it to 2007 model.

I have an Aussie GTI DSG built in June 06...it has launch control. I'm still running in the vehicles so I haven't tested at high revs...I did test it with the demo car and I must say it wasn't the quickest getaway, due to the immense wheelspin and tyre smoke that was generated when letting the brake off at 3000RPM. However it did put a smile on my face a mile wide!! Sure we don't need it and it's unecessary, but it's a pile of fun when the mood strikes you. I'm sure with some practice, with the right balance you can achieve a faster take-off than just plonking your foot on the accelarator (due to the bogging down). Shame you can't have this on the USA spec modeld...it must be a software re-program or something simple???
