Launch Control

[JCClem]

I seen mention of this in a couple of threads - is it just a case of building the engine rev's with the foot on the brake, or is it something special and if so do all dsg boxes have it?

Not all DSG boxes allow launch control, no. I believe it's only the pokier engines i.e. GT, GTD, GTi.

Google confirms:

- sport mode OR 1st gear with tiptronic
- disable ESP
- left foot on break
- right foot on throttle (it won't rev above 4k)
- release brake, travel back/ forward in time once 1.21 gigawatts is achieved

For what it is worth my dealer told me (after I had the car 3 months) it is not on the 7 speed boxes - I know it is not on my 1.4 TSI 7speed DSG.

So did he say which engines did have this mystical device?

It was more the 7 Speed box does not have it - no mention of engines.

The 7 speed DSG can't handle as much torque going through it at the 6 speed one can, hence you don't get the 7 speed DSG with the Torquey TDIs and the 2.0TSI engine (and above, as the range may increase).

1.4TSI (160PS) and below petrol engines will have the 7 speed dry clutch DSG.

Launch control would fry the clutches on the 7 speed DSG. Sitting at lights holding 4000rpm for the launch control (until the lights change) will make you look a bit of a *** anyway.

Well I'm slightly disappointed to find that my new car (160 TSi) will not have launch control, but on the other hand I can't see me using it all that often to say the least.

What are the advantages of a dry clutch DSG system compared to the wet clutch 6 speed? Why not just create a wet 7 speed?

[maisbitt]

7 speed dry clutch has less resistance to movement and so gets better economy, not only from the extra cog, but as it takes less effort to drive the gearbox than the 6 speed that has an oil submerged clutch.

That oil bath on the 6 speed does offer a lot more protection for the clutch and makes it a lot more resilient, hence its use on the torquier engines.

A wet 7 speed clutch will probably end up having negligible economy gains over the 6 speed, rendering it pointless.

Thanks for the info; is this why the power is 10bhp down on the old GT?

Also does this mean the engine management should not be tinkered with as the DSG cannot handle more power?

the torque is the same at 240nm. Understand its more to do with better fuel consumption

[maisbitt]

I think VW probably didn't want 2 versions of the same engine in the range, 160PS seems a good compromise between having a 140 and a 170 version.

I've read somewhere that the 7 speed DSG is only rated for 250NM of torque, and so can't be used for the TDIs (140=320NM, 170=350NM), or for the 2.0TSI, whereas the 6 speed is rated for 350NM.

So there isn't much room for upping the output on the 1.4TSI or 2.0TDI 170 if you have a DSG. The manuals can handle much more power going through them.
