FYI - not that I use LC much at all, but I couldn't get a good launch a while back and after taking it to the M tech at the deale he said there was a tranny fault preventing it from performing a full launch. It's not the Euro 4K rev like launch but it's tons better after having the dealer clear the fault code.

We kind of have the crippled version of the launch control in the states.
General consensus is that if you put shift speed into S6 and stomp on the gas from a stop, you will do much better than our launch control ever will.

Launch control on a US Spec M5 only works about 20% of the time, so if you are just having fun and have the time to keep trying over and over again, eventually you'll get a good launch out of it.

But usually you like it to work the first time so just throw it in S6, mash about 50-60% throttle and hold it until the car gets moving about 20mph and then wait for the tires to grab and punch it and go through the gears. Much more reliable and faster too.
