Help with Launch control
I tried to use my launch control today without success. The engine was properly warmed up, DSC disabled, and the trans in S3. The launch control flag wouold activate only when I moved the shifter forwartd and then release it. With the LC active, I would then move the shifter forward and hit the gas. The RPM's would run up to 3K and surge up and down. When I release the shifter, the car just moves forward at idle speed and the laucn control light goes out. I have activated the LC before, but never actually used it. Is there something that I'm doing wrong or is it a service issue? Any help wpuld be appreciated.

I have never gotten the LC to work worth a shit. There is a serious delay after you letting off the shifter as to when the car actually launches.
You are better off drag racing the car in auto mode because it will shift more precisely and LC makes you use manual mode. LC will engage auto shifting ONLY IF you have the pedal all the way to the floor but that just results in violent tire spin. I gave up on LC. Brian

Mine works seamlessly. DSC off, D3 or S3, lever forward and then mash throttle, release lever and instantly launch.
By the way, with the Michelin PS2s at low pressure even, launch control was an utter waste of time, rubber, and gas. Like Brian said, all my M6 would do is scarily go sideways, forcing me to let-off the gas in order to avoid a wreck. But, now that I have P Zeros, I'm getting exponentially better traction and the launch control is actually really effective and quite fun. |

Activate Launch Control Launch Control is available when the engine is warmed up, that is, after uninterrupted driving of at least 6 miles/10 km. 1. Deactivate Dynamic Stability Control 2. Select Sequential mode with driving program 3 3. With the engine running, lightly apply the brakes with the left foot. 4. While the vehicle is stationary, press the selector lever forward and hold it. 5. Fully depress the accelerator pedal. The starting engine speed adjusts. 6. If necessary, change the starting engine speed by 500 rpm via cruise control. 7. Release brake. When the selector lever is released, the vehicle accelerates. Keep the accelerator pedal depressed. Upshifting occurs automatically as long as the accelerator pedal is fully depressed. Notes Launch Control is available only after a certain distance has been driven.

Thanks for the input. It probably isn't very useful to me, but I do want to make sure it works. Im following all the correct procedures, but it doesnt launch when I release the lever. I guess a service call is in order, although I don't want the dealer to have all the fun.

Make sure you have driven the car at least 3-5 miles and that is warm.
Make sure traction control is off Press break and when lever is pushed forward make sure flag shows up You can adjust revs launch (ie from 3000 down to 2500) when you are about to launch when you are floored down with the gas and the lever still forward reduce the launch RPM with the left steering wheel speed adjuster for the cruise control . Let go the level around 2500 to prevent wheel spin and better launch. Don't release the gas at all You won't be able to do another one like in the next 20 min or so |
