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

More Information

Easy to set up and maintain
Your FLEX transponder is easily installed by using the holder and clip. This should be done at a maximum height of 60 cm (4 ft) above the ground. FLEX transponders are rechargeable: A full charge takes approximately 16 hours. A fully charged transponder will easily get you through a race weekend. It will keep working for a minimum of 4 days. The transponder is dirt, weather and shockproof and easily cleaned with a damp cloth or brush. Use a cotton tip to carefully clean the connector pins.

Insurance and warranty
Your subscription comes with insurance. It covers damage as a result of accident or fire – but not theft or loss. This means MYLAPS will guarantee the device keeps working and is in good order. We provide an unlimited guarantee for the duration of your subscription. Should any problems occur during normal use – as described in the manual – MYLAPS will repair or replace your transponder free of charge. See our terms and conditions for further information.
