Open Lap is a simple, no-nonsense slot car race management app for Carrera® DIGITAL 124/132 systems.

In a nutshell, Open Lap lets you

- connect your mobile device via Bluetooth using Carrera AppConnect®.
- take it easy during free practice, go for fastest lap in qualifying, or compete in lap or time based race sessions.
- get informed about important events, such as fastest laps or low fuel conditions, by personalized voice messages.
- adjust vehicle speed, brake force and fuel tank size for each car individually.
- measure up to three intermediate or sector times (S1, S2, S3) using Carrera® Check Lane or compatible equipment.
- send out the pace car in case of emergency, or temporarily disable lap counting during a "yellow flag" phase.

Please note that it is necessary to enable location services on your device to connect to Carrera AppConnect® via Bluetooth on Android 11 or lower. Also some features, such as the start light and pace car buttons, require Carrera® Control Unit firmware version 3.31 or higher. Carrera® Check Lane support requires at least firmware version 3.36.
