Leon, you should be able to set the speed through accessing the VSM in the normal way through the dash, you could do it with the PC tool but I don't think its nesarssary, unfortunately I'm out of. The country and don't have access to my notes, maybe swoop will jump in and help you with this one. I if you can access calibrations you will find the settings there.
