2012 335i DCT "soft launching" and Procede v5?
I'm thinking about getting a Procede and want to check on something with you guys before I seal the deal.
The DCT has a particular "hidden" feature that I've grown quite fond of: Instead of using launch control to launch the car full blast, one can actually from a standstill slam the throttle (to the kickdown point) with all systems in normal mode (DCT in normal automatic D mode, sport mode off, DTC/DSC fully active) and the engine will rev to about 3000-4000 rpm before engaging the clutch swiftly but smoothly for a very nice controlled launch with minimal wheel spin. I believe you can in fact have the DCT in either D or S mode and the sport button on or off according to your preference, and this will still work. I actually like this much better than the rather violent and conspicuous launch control feature, and I think it's a smart and creative use of the kickdown switch in combination with a DCT box! So I was just wondering, since the Procede modifies the DCT shift logic in various ways, would this feature still work with the Procede? |

Cool stuff, didn't know that (but I drive a 6mt)
The Procede doesn't change anything about the shift logic as it has no direct control on the dct. But it does remove torque to ease shifts (remove timing briefly) |

http://www.1addicts.com/forums/showt...launch+control One thing that does concern me about your method though, especially when you add proceded/more power - do you have DTC traction/stability control on/off etc? I would of thought that on any road that isn't smoother than a baby's arse cheek, it would cause them too interfere with the fun if turned on - especially when modded (something that the stock LC system fails on massively when modded, as you can't use it with everything off ). |

From reading your post, the 335 seems to differ from the 135 in a few ways. For one, my LC "works" regardless of whether I have DTC in play mode or completely off. I say works in quotation marks because with the DTC off the LC is basically little more than a very efficient way to burn rubber. |
