How does it work?
The track you’re racing on has a MYLAPS system installed at the start and finish line and at intermediate points along the track. The system picks up the signal sent out by the transponder mounted on your car. This signal is analyzed and lap times are measured. The system knows exactly on which lap you are and what your position is. This data is passed on to race officials and is published to your personal MYLAPS account on mylaps.com.
*Ask your club or race organization if they support MYLAPS transponders
