135i dct - possible to burnout [warm up] the tires
without using the second launch control option?
i know there are two types of launch control in our cars one is the burn out, the other is the launch control. im going to hit a local drag strip soon, and wanted to know if i can burnout using the brake + gas. brake the front wheels and do a slow, low rpm burnout to moderate the wheel spin is that ok for our cars?

Like the start of this I've tried doing that then getting on the brake and it doesn't work, it cuts the throttle. I'd like to find a way as well. I know some M3 guys managed to reprogram the DCT so you could do a burnout. http://www.m3post.com/forums/showthread.php?t=538284 |

To get proper launch control (checkered flag), you need to have DTC on, be in S or manual, have the sport button pressed and the engine has to have reached a certain temperature. Then one foot on the brake, one on the accelerator and it will rev up to around 3000 rpm and sit there until you take your foot off the brake. This is a bit useless, and you never know if it's going to work or not. Would love to just be able to do a normal burnout. |

easy
1. make sure you have driven atleat 10 km [it wont allow it for less] 2. come to a stop and press the brake during all of the next 3. press the DTC button ONCE 4. press the SPORT button 5. move the gearstick to S\M 6. WHILE PRESSING THE BRAKE - hit the gas pedal to the max! [make sure to push the kickdown switch under the pedal] you will see the checkered flag on ya dash, and revs will stand at ~3700 rpm when you feel ready, just leave the brake pedal and get ready to rumble to do a burnout you just press the DTC for 10+ seconds press the sport button move the gear to M1 hit the gas

Completely stock exhaust, I tape a lapel mic to the diffuser and run the cable through the car to the camera. That's why the exhaust sounds good because the mic is right next to it |

by the way, another question
on the DCT trans, is there a way to hit the limiter in manual mode without it shifting to the next gear?

I've known about the "real" LC with the checkered flag since I got the car (it is in the manual after all) but that total TC off with the quick rev I did not know about.
I tried it on my way home last night... fast rev up and car goes sideways quick - lots of fun! thanks for the tip on that as there are times when you want to show off a bit :P

Probably not something to use all the time though. Last time I did it I spun all the way through first and second and when I changed into third it threw the car into limp mode.

Excerpt from 2011 135i owners manual: Launch Control enables an optimum acceleration when starting off on a road surface with good traction. Do not use Launch Control too often; otherwise, the powerful stresses on the vehicle will lead to premature component wear.< Launch Control is ready for use when the engine is at operating temperature, i.e. after uninterrupted travel of at least 6.2 miles/10 km. 1. With the engine running, step on the brake with your left foot. 2. Activate Dynamic Traction Control (DTC), refer to page, 72. 3. Activate Driving dynamics control, refer to page 55. 4. With the vehicle stationary, activate the manual mode and select 1st gear. 5. With your right foot, push the accelerator pedal past the resistance point. The acceleration speed is adjusted. A flag symbol appears in the instrument cluster. 6. When you release the brake pedal, the vehicle accelerates. Keep the accelerator pedal floored. 7. The upshifting occurs automatically as long as you keep the accelerator pedal pressed past the resistance point. Launch Control will be ready for use again after you drive a certain distance. Launch Control is not available for use during the break-in phase, refer to page 104. To maintain driving stability, keep DSC activated whenever possible. |
