Quick Start

Powering Up

Using optional OBDII cable (2008+ vehicles)

• Plug one end of the cable into the RaceCapture unit
• Plug the other end of the cable into your car's OBDII port.
• Power and OBDII data will be provided to RaceCapture/Pro.

Powering via 12v

Plug the supplied power + CAN data pigtail into the RaceCapture system.

• Connect Red to 12v
• Connect Black to Ground

Testing on the Bench

You can power RaceCapture/Pro with just the included USB cable. Simply plug one end into your computer, and the other end into the USB connection on the front of the unit.

• Note: When powering only with USB, the voltage reference output will only be at approximately 4.7 volts, which can cause a mis-reading of sensor values. When precise sensor readings are required, provide 12v power to RaceCapture.

Install the RaceCapture app

On Desktop

• Windows and OSX

USB Drivers

• Windows 10/11: Windows 10 has built in USB drivers that support RaceCapture; no separate driver installation needed.
• Windows XP, 7, 8: Not supported due to outdated video drivers, but may work depending on the video hardware used.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.

On Mobile

• Google Play
• Amazon App Store
• iTunes

• Not sure what tablet to use? See our list of recommended tablets

On Raspberry Pi

More advanced users can run the RaceCapture App on a Raspberry pi for a more dedicated dashboard experience.

• Learn more in the Raspberry Pi Guide

Connect to your RaceCapture system (dashboard)

Use an Android, iOS or Raspberry Pi device as a dashboard in the car:

Bluetooth (Android Only)

In Android Settings, pair your device with the RaceCapture system.

• Note: Default bluetooth pin is 1234. You can change this later under Setup / Wireless in the app.

WiFi (iOS or Android)

In your mobile device WiFI settings, connect to the RaceCapture WiFi network.

• By default, RaceCapture will setup a WiFi network starting with 'RaceCapture', with no password. You can immediately connect to this network.
• Note: You can change the WiFi password later under Setup / Wireless in the app.

Launch the RaceCapture app

Once you've linked the Bluetooth or WiFi (Mobile), or USB (Windows or OSX) launch the RaceCapture app.

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.

Using the RaceCapture app

See the RaceCapture App User's guide for a full tour of using the app and setting up your system.
