#B4mad racing

Community driven SimRacing data collection and analysis.

A telemetry data collection and analysis pipeline for simracers :racing_car:

The pipeline start at CrewChief. This means we can take data in from any simulation that CrewChief supports. CrewChief will send your simulator telemetry data to an endpoint hosted on the Operate First Community Cloud. You can then visualize your telemetry data in our B4mad Pitwall or do some data science

Installation

1. Install CrewChief
2. Enable the telemetry collection by checking 'MQTT Telemetry enabled' in the CrewChief Properties
3. Choose a 'MQTT drivername' in the CrewChief Properties
4. Enable text to speech
5. If all works you should see connection messages in the CrewChief console
6. Join our Discord and say hello :wave:

Drive some laps to send some initial data. Now any time you run your simulator you will be sending data. If anything doesnt work, check out the FAQ.

Coaches

At Paddock find your drivername and enable the coach.

Visualization

Head over to the B4mad Pitwall and explore your recent sessions or signup for an account to create new dashboards.

Check out the flux scratchpad for some flux query examples.
