Does the launch control do as much long term damage as the old E46 M3's ie, you are only advised to use it a max of 3 times!!???
Nope Launch Control can be used as many times as you want. After each launch control the car needs to cool oil temps before it will let you do another one. I have not lag in kick down. All in all its a very good gearbox...

Thats about it...my preference is DCT...its totally different from the E46 SMG which I also really liked despite its many quirks. I don't have any problem with "lag" that seems to mostly annoy USA DCT drivers but 6 years of M3s with SMG probably allowed me to adapt quicker. I think a test drive should decide whether you think the DCT is worth the premium...it was for me and I hung on until I found a 09my M3 with DCT in January at what turned out to be a good price. 3000 miles later I have absolutely no regrets but the M3 is so good that I'm sure manual box drivers think exactly the same thing.

Thats good to hear from you guys with the DCT.
Naz - that ACS front splitter - is it similar to the Vorsteiner one or completely different?? Also, in your pics i cant see the rear diffuser?? Is it fitted yet - any pics of it?? Ive just ordered front and rear CF splitter/diffuser from Vorsteiner so its too late now - but would love to see pics of it. I assume you will be coming to the M3 meet im organising so look forward to seeing it in the flesh!!! Steve

Put the smg in s6 with dsc of and it changes gear between 60-80 millisecs and it makes a big difference to acceleration. If you feather the throttle slightly on change up the changs can be velvety smooth. The blip on downshifts is perfect, and does it alot better than i could do in a manual.

Have a look at this video of M6 vs 997 turbo from driversrepublic the results are suprising but it demonstartes the effect of the fastest setting on the smg. Please watch all the video.

ive tried to embed it but im a bit thick
Sorry to drag up an old thread, just been going through them so to speak!

These two are interesting in comparison to say the least!

2/ During normal driving you are sitting at say 60 in 7th gear and then you floor the accerlerator.What happens is the revs immediately jumps from 2000 to 6500 revs approx and then it changes into 4th or 3rd a second later. Feels like forever. Does ths happen with the M3?
3/ Does anyone else have a DCT 335i as I can't get the launch control to work?
4/ Apart from the above can't really see much of a difference from the six speed box.

Dougie.
I have an E93 M3 DCT.....

1. Nope my M3 doesn't do that
2. Nope revs seem to change at the same time as the downshift
3. Assume you've gone past 1250 miles already? If the process is the same is the M its DSC Off > set to highest S shift mode (S6) > foot brake and hand brake must be off/untouched (so you need to be on a flat road!!) > hold DCT lever forward > gas pedal to the floor > dash will show the chequered flag and revs will sit at 5k > release DCT lever on hold on for dear life!!!! If you lift off at all or change gear after starting off it will revert to normal mode and you'll clatter off the rev limiter
