RaceCapture App User's Guide

The RaceCapture/Pro V2 firmware and app represents a major upgrade to the capabilities of the original RaceCapture/Pro system.

What's New

Multi-Platform, touch oriented application

Capable of running on Windows, OS X, Linux, iOS and Android, the new RaceCapture app will ultimately combine RaceAnalyzer and the current Mobile app into a unified configuration, dashboard and analysis solution.

With this beta/preview release the RaceCapture app will initially support configuration for RaceCapture/Pro system running the V2 firmware. Dashboard and then Analysis features will follow to make the official application launch.

Automatic Track Detection and configuration

The RaceCapture/Pro firmware supports automatic track detection and configuration, supporting up to 40 of your favorite race tracks.

When RaceCapture/Pro is powered up and GPS locks on, the system searches for a track within a 2 mile radius. If one is found, the start/finish line and sector points are automatically configured, enabling lap, sector and predictive timing features without having to alter configuration.

The latest race track configurations can be automatically downloaded and synchronized from http://www.race-capture.com via the application. If your track is not in the list, email us at [email protected] and we will work to get it added.

Automatic configuration can still be disabled and manual start/finish and sector points can be defined.

Multi-Sector Timing

We've expanded timing from a single split point to up to 20 sectors, enabling true sector based timing. The sector timing information are exposed as two additional channels:

• sectorTime - indicates the time of the last completed sector
• sector - indicates the last completed sector

Separate Start/Finish Lines

Not yet implemented To enable auto-x/rally/hillclimb scenarios we've enabled the ability to define a separate start and finish line.

The beginning of a lap is triggered by the combination of a start point which defines the general area where the race car is staged, and a launch detection algorithm combining a speed and g-force delta threshold.

The completion of a lap is detected using the conventional GPS target detection mechanism.

Predictive Lap Timing

A new predictive lap timing algorithm augments current 'lapTime' channel with a new channel called 'predTime'.

Once a lap is completed, the data is used as a model to predict the next, ongoing lap. The predicted time sample rate is configurable up to the native GPS data rate.

CAN bus expansion

a single CAN bus channel is supported using the CANx expansion module, which plugs in to the expansion port next to the green terminal block.

The CAN feature can be configured with a variety of standard baud rates.

CAN send and receive commands are made available via Lua scripting and can be combined with the Virtual Channel feature.

OBD2 support

Enabled via the CANx module, standard OB2 PIDs can be queried and mapped to RaceCapture channels along with other sensors.

Due to the design of the OBD2 protocol, individual channels (PIDs) are requested sequentially, so individual channel rates decrease based on the number of channels enabled.

Virtual Channels

A virtual channel (aka 'Math channel') can be used to derive new channels from existing channel values. Examples include:

• Detecting gear based on RPM and speed ratios
• Turbo intercooler efficiency by calculating the difference between inlet and outlet temperature probes
• A calculated 'engine load' indicator by integrating RPM + Manifold Pressure Sensor value.
