Dennis - What lap timer app are you using on your phone? What mounting system are you using to hold the phone to the steering wheel? How quickly can you move it to another kart during a pitstop?

welke app is dat op je gsm?

Bonjour super relais je voulais savoir où vous avez trouvé le support gsm et l’application. Merci à vous

instead of speed, set the "delta" speed between current lap and best lap... so you can find easyer when you have a good engine or bad
