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®, or a suitable serial to USB On-The-Go adapter cable. - 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. Some features, such as the start light and pace car buttons, will require Carrera® Control Unit firmware version 3.31 or higher. Carrera® Check Lane support generally requires at least firmware version 3.36.
