Powered by GNSS
At the heart of CircuitStorm is a Global Navigation Satellite System based data logger. GNSS offers an excellent price point for entry into race car data logging and analytics. There are many GNSS and GPS receivers available to choose from, as well as some best practices for their use. Please read our GPS for Motorsports page to familiarize yourself.
Powerful Video Processing Engine
CircuitStorm allows you to combine your data and videos on your Android device. You can generate overlaid video showing a number of data channels, as well as picture-in-picture video to show an alternate view or to compare to another run or driver.
Here is an example of a video overlay created with CircuitStorm:
CircuitStorm allows you to use a combination of video sources, including the front or back facing internal camera, a Wi-Fi camera, as well as 2 additional auxiliary cameras that you manually control.
Petrel Cloud Integration

What Do I Need?
You will need to supply your own Android phone or tablet. Read the Hardware Requirements.
If your vehicle is legacy OBD II compliant (1998 to 2007), then you want to add a Bluetooth OBD II reader. This will allow you to log throttle position and RPM which are key for driver coaching as well as vehicle tuning.
If your vehicle is CAN OBD II compliant (2008 and newer), then consider the RaceCapture/Track data logger. This will allow you to log OBD and other CAN bus channels at higher sample rates. On some vehicles (FRS/BRZ/GT86, for example) you can also log brake pressure and steering angle.
If you want to log values such as throttle and RPM but you don’t have an OBD II compliant vehicle, or have a standalone ECU with CAN bus support, then consider the RaceCapture/Pro data logger. This data logger features analog sensor inputs, CAN bus connectivity, internal accelerometer and gyros, and much more. You can also run brake pressure, steering, or custom sensors with this logger.
