Title: Launch control?
Post by: smorg00 on 13 May 2014, 14:04
I did a quick search to see if this had been discussed before but couldn't find anything specific.

So today I noticed that if I put the car in gear and floor the accelerator, the revs will not exceed 2.5K. I tried it in 1st and 2nd gear and same thing.

A colleague reckons it's launch control? I didn't release the clutch by the way, the car is still too new for that kind of thing! I can't help thinking though that if I had popped the clutch, all that would have happened would be a lot of wheel spinning and flashing lights showing the traction control kicking in :)

Was the engine cold? Until the engine is up to temp it won't let you rev any higher to protect the engine. Even does this on our VW crafter at work lol

I had just parked up after a 20 minute drive, didn't take note of oil temp or anything like that so engine wouldn't have been classed as cold.
Good luck with the collection of your GTD by the way, it really is a lovely car to drive :)

It's just engine protection. The GTD doesn't have launch control. Only DSG equipped GTI's and R's I think... I'm sure someone will pop up and confirm that!

I watched a video a while back and correct me if I'm wrong, it's a manual GTI with launch control.

I'm not sure if this is launch control or even if this guy did it right but it's a manual.(That I'm sure of lol!)
I just hate the vibration the car did on acceleration makes me think he's harming it. It revs up to 3K as you can see but he seems to press something before launching (auto hold????)

Also, lots of videos of the Mk6 GTD with launch control on youtube but I can't confirm if the Mk7 is the same.

The YouTube vid isn't launch control.To do a proper launch control you need a DSG gearbox.You turn off traction control,select sport mode on DSG,you put your left foot on the brake pedel,you release the handbrake,you give it some revs to about 3000rpm then take your foot off the brake.Then hang on.After a few goes you learn how to control it somewhat so you don't get too much wheels pin.It works better in an R though.

Ohh alright got it. I don't think I'm going to try it any time soon though, I'm pretty satisfied with the car's launch without it! Also I read somewhere here that it might affect some warranty works on the car if you do it too many times? Wouldn't want that considering I have the 2-year warranty extension as well.

As already said, it's just engine protection, most modern cars won't rev beyond about 3k with the clutch in, GTD's do have launch control btw.

They do (DSG's) have launch control - my MK6 GT TDI DSG had it to - AFAIK its on all the 6 spd DSG gearboxes

Intrigued. Is it as stated earlier in the post.

Its quite epic tbf in the GTD, the traction the car keeps over driving yourself is quite something. Only tried a few times you need to switch off traction control and put into sport mode in a certain order too.  One for the lights  :wink:

Launch control is only required on an auto box - you don't need it in a manual because you can launch it yourself by dropping in the clutch at the right point.

That's all the launch does, it allows you to put your foot on the brake and let the revs rise before dropping in the clutch when you pull your foot off the brake.

Works pretty well too, though I have no idea when I would ever try it again (you have to do these things once though huh!)

It's not really a requirement for the vast majority of people. Only those few who may want to track their car or do 1/4 mile runs. Launch control really only works with a DSG gearbox as with manual you are never going to be able to match the gear changes and hence your not going to get the same ferocious launch. Plus for it to work to its full potential it really also requires awd for traction off the line. A DSG R is a perfect platform for launch control

This is quite interesting.. Mk6 GTI tested.

Well if the GTD's is anything like the GTi's - then the LC has been configured to use too many revs as with the TC off there is far too much wheelspin and some tramping ......

I think my car is faster going flat from rest in sport mode!

It bodes well for the R as it produces dramatically uncomfortable acceleration in a Nissan GTR or Porsche 911 Turbo .....

I've only tried it once, however it seemed to control the wheel spin well on my gti... It will depend on surface etc though I'm sure....

It's hard enough to prevent tramping in a GTD at the best of times when pulling away with more than 60% throttle from a standstill, I can't imagine the situation improving with use of launch control.

I don't want to veer off topic but I wonder if those who have changed to shorter/stiffer springs still experience the same degree of tramping?

I dont know if its the warmer roads, the bridgestone being worn in completely, or the eibachs but i havent really been suffering from 2k+ miles onwards and that is after i put the springs on...

I've never had tramping in my GTD... wheel-spin yes, but tramping... no.

You have those dodgy Bridgestones though, don't you? :laugh:

Could be the springs, it could be the warmer weather - the Bridgestones are very temperature sensitive, could be that they're worn out... or a combination...
