Predictive Lap timing

RaceCapture/Pro offers predictive lap timing, which relies on a robust track detection system leveraging hundreds of track maps worldwide.

How it works

• When GPS receives a lock, RaceCapture will search for a nearby track.
• If a track is detected with one configuration, it is automatically selected.
• If a track is detected with multiple configurations, the RaceCapture app will prompt you for which configuration you're using.
• If no tracks are detected nearby, the RaceCapture app will offer the ability to create a track on the spot.
  • If you're not able to immediately create the track, you can do so later under Setup.
• Track not found? Submit the track to us and we'll get it into our online database.

Analysis

The RaceCapture app will automatically record your session when triggered by the threshold you configure under Setup / Automatic Control.

• Note: The system default is to trigger on Speed

To view the data, enter the Analysis mode and load an existing session. The session will be automatically named with the local track or with a timestamp.

You can load a session by pressing the (+) button at the bottom of the pop-out list of laps, or by pressing the gear icon on the dashboard and selecting Sessions.

Reviewing Laps

If the data contains lap times, the laps will be shown in the dropdown list on the right. Select the laps you wish to compare; up to 4 laps can be compared at once from the same session or different sessions.

Navigating data

Cursor across line chart

Swipe across the line chart to correlate different points with the position on the track map.

Playback Control

You can also use the controls at the bottom to automatically play back the selected lap(s).

Swipe across the data to compare various points correlated with the position on the track map.

• Zooming For line charts, you can zoom on the data using a two-finger pinch gesture, or using the mouse scroll wheel or your laptop's trackpad scroll gesture.

Selecting time vs distance

You can switch between time and distance data comparison by accessing the chart options, or pressing the -> or clock icon in the line chart.

Reviewing raw data

If your data contains no laps, such as data from a static test or dyno pull, the data will be present in one entry under the loaded session. Select this entry to view the data. The RaceCapture app will auto-select the Time dimension if it detects no significant distance traveled within the data.

Comparing laps / runs between sessions

You can compare data between sessions if they are in a coinciding location - just load multiple sessions and select laps between those sessions.

Exporting Data

You can export your sessions from your list of saved sessions.

Android

• Press the gear icon to access your session list
• Select the session you wish to export - Android will let you save it to a file, share to email, or any other app that accepts files.
• Note: - if you save it to your local device, you can download it to your computer using a USB cable when your Android device is set up in File Transfer mode

iOS

• Press the gear icon to access your session list
• Export this to your local iOS device storage.
• Connect your iOS device to your computer using a USB cable.
• Access the iOS device using the iTunes file sharing capability. We recommend iFunBox as an easy to use tool.
• Copy the exported log file from your iOS device to your computer.

Importing to 3rd party software

The RaceCapture log file format is plain CSV, which can be imported into 3rd party software.

• RaceRender provides native support for the RaceCapture log file format. See the exporting to RaceRender guide.
• DashWare has been used by RaceCapture customers - Rowan Hick has a write-up on Dashware integration.

System Setup

You can configure all of RaceCapture's options under Setup.

When the RaceCapture app detects the connected hardware, it will read the current setup from the device.

• The setup information is presented as a series of pages, by topic.
• When you change something on a setup page, you'll need to Write the changes back to the RaceCapture device before they take effect.

Explanation of buttons

• Save: Save the current RaceCapture setup to a file, for backup.
• Open: Load a previously saved setup file.
• Read: Read the current setup from the RaceCapture device.
• Write: Writes any updated changes back to the RaceCapture device. Note: when you see the write button glowing / pulsing, it means there are pending changes to write back to the RaceCapture device

Race Tracks

On the Race Tracks page you can create a custom track, which will be included in the library of track maps for automatic detection. To create a custom track, turn off 'Automatic race track detection' and then press the add (+) button. You will be presented with an option to create a circuit or Autocross (point-point) style course. Follow the on-screen instructions to create your track.

GPS

The GPS page allows you to adjust the GPS sample rate and enable/disable various channels.

• Note: We highly recommend you keep the default channels enabled for proper operation of analysis and lap timing.
• 10Hz is the recommended sample rate for the best balance of performance / accuracy. Getting the best GPS performance

Race Timing

These enable the lap timer and predictive lap timer. Leave these 'on' to enable these features.

Analog Sensors

Here you can configure and calibrate your analog sensors.

Pulse/RPM sensors

Here you can configure and calibrate RPM and pulse-type sensors, such as wheel speed.

Digital In/Out

Here you can configure the General Purpose Input/Outputs (GPIOs) for your RaceCapture system.

Accel / Gyro

The recommended mounting orientation for RaceCapture is square with the chassis, with the harness connectors facing the front of the vehicle.

• You can re-map channels by re-assigning the physical axis to the mapped channel.
• Once defined, you can calibrate the accelerometer + gyro by pressing the calibrate button, and then pressing the write button to write the calibration back to RaceCapture.

CAN bus

To enable CAN bus communications, set the CAN bus setting to ON. CAN bus baud rates are configurable; common rates are 250K, 500K and 1MB. RaceCapture defaults to:

• 500K for CAN1, which is common for OEM and aftermarket ECUs
• 1MB for CAN2, which matches the standard for our CAN bus accessories.

CAN bus mapping

RaceCapture offers a powerful CAN bus mapping capability, allowing you to map CAN bus data frames to real-world sensor values.

OBDII

You can select from a standard list of OBDII channels on the OBDII configuration screen.

Selecting sample rates

For channels that require a faster response rate, like RPM and TPS, we recommend 10, 25 or 50Hz. More slowly changing channels like EngineTemperature should be set to 1 or 5Hz.

• Note about unsupported channels: If your ECU does not support a channel, the value will remain at 0. RaceCapture will time-out waiting for a response from the ECU, which will affect the performance of other channels. We recommend removing all unsupported channels to ensure optimal OBDII performance.

Automatic Control

Wireless

You can configure RaceCapture's WiFi for both Access Point and Client mode.

Client Mode

To enable client mode, specify the SSID and password for the network you wish to connect to and turn the client mode switch to on

Access Point Mode

To enable the RaceCapture access point, specify the SSID and a password.

• Note: If specified, passwords must be minimum of 8 characters. Leave the field blank to create an open network.

Real-time Telemetry

With the real-time telemetry feature you can live-stream your data to Podium so you can compare and share laps and runs with your friends. Enable by setting your Podium Device ID provided by your Podium Account

See the RaceCapture real time telemetry setup guide for details on setting up this feature.

Scripting

You can customize the behavior of your system by writing small Lua scripts; you can do things like:

• Create live math (virtual) channels that are calculated on the fly
• Broadcast Custom CAN bus messages
• Control a fan based on the temperature of an analog channel (e.g. EngineTemp)

See the Lua scripting guide for a complete how-to, including helpful examples.

Diagnostic Logs

To view the log messages provided by the RaceCapture unit, you can enable the Poll log check box. You can copy the current log to the clipboard by pressing the Copy button.

• Note: These logs are useful for diagnosing issues with your RaceCapture unit.

Firmware

Here you can update your system's firmware, perform a factory reset, which restores the system to its original settings, or perform a reboot of the unit without needing to do a power-cycle.

• Note: Before updating your firmware, be sure to save your current configuration to a file.
