Launch control - what am I doing wrong?

[M5MUTANT]

Thank you for your replies, I will try again today. Will ambient temperature cause it not to work? Although I drive the car more than 6 miles each time I have tried it, it hasn't been over 50 degrees F outside when I have?

* DSC off (not MDM; all the way off)
* transmission in sequential mode; it was already in the most aggressive shift setting ("3")
* left foot on brake
* shift lever all the way forward

At this point, there's supposed to be a flag on the instrument panel, but nothing happened. (Where does the flag appear?)

What am I doing wrong??

Don't push brake too hard. It work with my car.
