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 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. When you drive on a track with a MYLAPS RC4 timing system installed, your account will also show you information about the connected voltage and ambient car temperature.
