well there are two ways of launching the car.... redlining and then extensively abusing the clutch to give max performance and limiting wheel spin....
other is rducing the wheel spin by less rpm, like dus engage the clutch at low rpm so that there is less wheel spin and then floring the throttle...
the launch controls works onthe second method.... and basically is in high end cars wher the clutch is more or less binary, i mean is either it is on or off..... like in formula1....
so launching our normal day cars will be the best on first method.....

this is my own observation and if anything is wrong then please correct me
