If that is true, there isn't really a valid case for LC

I have a GTech that I'll try out after break in to validate that.

Car and Driver's test yielded the following -

0-60 - 4.3
0-60 w/Launch - 4.1

I have launch control on the M3 - it is fun, but not something you would choose to use with any regularity, I would think. In the M3, one can lauch at different rpm - once in launch mode, you can alter the revs to which the car goes up to - from 4500 to 6500, I believe, in 500rpm increments. Not sure if the ///X Ms have this feature??
I think I've used it once only. It's way more fun driving on the track :)

A 4.1 second 0-60 in a 5000lb+ vehicle has GOT to be an eye opener :thumbup:

Launch control

What are the instructions?

(I can only find instructions for the SMG trans.. Not the auto.)

To activate Launch Control, the driver stops the vehicle, moves the gear selector into the M/S position and activates the Sports Power mode, as well as the M Dynamic mode, or respectively, the DSC-Off mode. Then, with the transmission in stage M1, the driver presses down the brake pedal and moves the accelerator to at least 60% throttle, setting Launch Control to standby. Standby status is confirmed by “starter’s flag” symbol in the instrument cluster. As soon as the driver releases the brake pedal, the vehicle will accelerate with full power in “genuine racing style.” In the process, the M Sports Automatic transmission automatically upshifts at the ideal points, with the fastest possible shifts and optimum wheelspin control. The driver may terminate the Launch Control process at any time by reducing the throttle position.

yep, that's about it.. manual mode, paddle shift to 1st vs 1Sport, brake on, gas to the floor - wait for the starter flag, sidestep the brake, keep gas to floor, hang on :)

B-line;
There are detailed instructions to activate Launch control in the M suppliment to the owners guide. I had read someplace a while ago that this programming had to be activated by the dealer but not sure how factual that is.

Sorry, I did too many drugs in the 90's and my memory isn't what it used to be.

The good news is, I can see through time.

Sometimes I can't remember what I did, then people tell me...the 90s were a blur. :thumbup:
