BMW's HAVE A HIDDEN LAUNCH MODE!

Yes, if your BMW has ASC+T, DSC or DTC then you have a hidden launch mode. That covers BMW's from the early 1990's right up to the present. This strange feature is a part of the traction control system and was known on the E31, E38 and E39 as a system to help get traction in poor conditions such as snow and mud - but, no-one really knew how it worked or what it did. The later models have the same hidden feature - does it really make a difference - or is it just a an old tale passed along each generation of BMW owners?
