Hey guys, new member here. I picked up a 2011 335IS DCT last year and have been enjoying it. It's currently FBO and the plan is to build a nice 10s street car. So wish me luck I'll no doubt need help along the way to do it.

I don't mind at all.
Best I could do was 11.5 @ 125mph I think. That's at the track on a prepped surface with PSS4S tires.
The trick is getting a DCT to "Launch" is super hard to do. I have xHP Stage 3 DCT tune and launch control set at 3000rpm but in the end just easing into throttle worked better for me the LC.
You might have better results with it but I can tell you any tuned N54 cannot use the stock DCT launch RPM, I think its like 4500 or something high.
yeah, I think I'll focus on getting the car to launch first. I have a dragy to measure progress. I am hoping I can tame the LC but it seems pretty difficult to work with because the only tool we have (that I am aware of) is xHP. I primarily bought it to adjust the LC rpm, and tune the shift rpms and tune the clutch engagement. The standard D mode drove around with shift points too low, and S mode 2-3 shift seems too high (around 4k) for part throttle.
I have a few questions about the DCT (GS7D36SG) that I don't know the answer to such as:
- Does it really have a limitation of 100 launches before it disables that feature?
- Does it prevent you from using LC if you use it in succession? What rules does it enforce? and Does xHP disable those rules?
- Does it feather the clutch in 1st, LC mode? If so how long does it feather it, what stall RPM does it target when feathering it?
I wish there was an engineering manual on the software portion of the DCT. (Please link if anyone knows of one, not including the M DCT Drivelogic Manual, since it doesn't go into enough detail) I think I'll most likely have to datalog a few LC events and see what I discover.
