Start it up

Plug it in

Unpackage the RaceCapture system and included OBDII cable and GPS antenna.

  • Plug one end of the OBDII cable into the RaceCapture Power/CAN port.
  • Plug the other end of the cable into your car's OBDII port.

LED status

Your RaceCapture system has a status LED that will indicate the current status of the system:

  • CAN - Shows activity on OBDII / CAN bus network, indicating data from your ECU and sensors is being received.
  • GPS - Shows GPS activity. Slow flash indicates acquiring a lock; rapid flash indicates GPS is locked.
  • Error - Indicates an error condition with the unit - see the RaceCapture app status page for details. It can also indicate an error with your Lua script (an optional feature of the system)
  • Power - Illuminates when the unit has power via 12v or USB.


  • Very fast green flash: Very rapid green flash indicates the unit is in bootloader mode, during firmware updates. If you see this when the the unit powers up and you cannot connect with the RaceCapture app, it usually means a failed firmware upgrade. You can resolve the issue by going through the firmware update process again.


Place the RaceCapture system on a level surface in your car, with connectors facing the front of the vehicle. This is the factory orientation for the accelerometers and gyro.

Note If you must install the unit in a different orientation, install with 90 degree orientation to the plane of the vehicle; e.g. flat/upright, on-edge, upside down - etc. Avoid installing at an angle. If installed in a non-standard orientation, you can go into Setup and re-map the accelerometer and gyro channels to match your changes.

Ideally, install the unit in a hidden location, shielded from heat and moisture. You can attach the unit with hook and loop fastener, if that is convenient.

Attach GNSS antenna

Attach the GNSS (AKA GPS) antenna connector to RaceCapture and screw to 5-6 inch lbs - just beyond finger tight to prevent the connector from vibrating loose. Do not overtighten.

Locating Antenna

  • Ideal: Mount the antenna on the roof of the vehicle, using the magnetic mount. Place the antenna with minimum 3 feet spacing from other transmitting antennas (car radios, cellular antennas, etc).
  • Alternate Mounting: You can mount it on the dashboard in clear view of the sky, or on the rear parcel tray under the back window. Note, this may degrade your GPS performance vs. roof mounting.

Download the app

On Mobile

Windows / OSX

Download the Windows or OSX app from the downloads site

  • Windows 10 and OSX: No USB drivers are needed for OSX or Windows 10.
  • Windows XP, 7, 8: Not supported due to outdated video drivers, but may work depending on the video hardware used. USB drivers will require installation instructions below.

First Time Setup

Windows / OSX

Connect the RaceCapture device to your computer via the supplied USB cable; this will also provide power to the unit. This is a good way to set up and test your RaceCapture system on the bench.


We recommend connecting with Bluetooth when using Android devices.

Connecting with Bluetooth

  • Ensure RaceCapture is powered.
  • Under your phone/tablet's Android Settings, navigate to the Bluetooth section.
  • Select the option to pair a device. Your phone/tablet will search for available devices.
  • Once the RaceCapture device is found, select it to pair.
    • Note: The default password is 1234 - you can change this later under Setup.

Connecting with WiFi

  • Ensure RaceCapture is powered.
  • Under Android settings, navigate to the WiFi section.
  • Wait until you see the RaceCapture WiFi network.
  • Select this network to connect.
    • Note: No password is required for the initial connection - you can set a password for your WiFi network later under Setup.


Due to iOS's limitation for Bluetooth connectivity, only WiFi connection is supported for RaceCapture.

Connecting with WiFi

  • Ensure RaceCapture is powered.
  • Under your iOS settings, navigate to the WiFi section.
  • Wait until you see the RaceCapture WiFi network.
  • Select this network to connect.
    • Note: No password is required for the initial connection - you can set a password for your WiFi network later under Setup.

Automatic Setup and Verifying Connectivity

The RaceCapture app will guide you through a brief automated setup and tour. During this process the connection to RaceCapture/Pro will be verified.

Alternative ways to power


You can power RaceCapture using the included USB cable, plugged into your car's USB charger.

  • You can optionally power RaceCapture from a battery like the kind you would use to recharge a phone (1000 mAh or higher recommended)
  • Note: OBDII is enabled by default on CAN1; CAN2 is recommended for secondary sensor networks.
