Logging
Here's just an example of what kind of data you can record with Race Capture Pro:
Software
A data acquisition system like this wouldn't be complete without software. Race Capture Pro includes software which allows you to configure the hardware settings as well as perform analysis on your racing data. Read on for more details!
Control
Race Capture Pro doesn't only collect data; it can process it in real-time and control devices on your race car.
With Race Capture Pro's control capability you can do things that range from simple to sophisticated. Things such as:
- Activate a fan when a temperature threshold is exceeded
- Log data at a higher resolution near a certain GPS coordinate, like at that one problematic corner of the track
- Control an intercooler sprayer based on temperature and boost level
- Intercept and re-map an OEM sensor to override stock engine management behavior
- Experiment with active aerodynamics by controlling a wing based on GPS velocity
- Lay down a thick smoke screen against your competitors ;)
How does this work?
We've embedded a simple yet powerful scripting language right on board called Lua, which lets you easily create commands to read sensors and activate outputs based on logic you define. It's easy, and you don't have to be a firmware developer!
And if you need help getting something to work, our community will get you started with sample scripts, help and reference - sharing at its best.
Open Source
Race Capture Pro isn't just a powerful data acquisition and control system; It's an Open Source Hardware and Software project. We will open the design for your inspection, tweaking, and customization. No secret file formats and no expensive, proprietary add-ons. Frankly, we think this is silly and it's time that a project like this exists to serve the enthusiasts first. And we're excited to share it and see where we all can take it together!
When will we release source code and hardware design files? Our plan is to release source code and designs upon fulfillment of the last IndieGoGo campaign Race Capture Pro unit, before we make it available in our regular store and via distributors.
Software / Firmware Features
Race Capture Pro includes software that allows you to configure the system and perform analysis on your recorded data: Race Analyzer.
The powerful 32 bit ARM processor combined with the onboard firmware allows Race Capture Pro to record real-world values in real time - not just raw values that have to be dechiphered later as found on other, even more expensive systems.
Configuration
GPS
- Configure Latitude, Longitude, Velocity and Time channels. Logging rate of 1, 5 and 10Hz are supported
- Configure start / finish line detection for Lap Count and Lap Time
Accelerometer / Yaw
Measure G forces in 3 axis using one of the most precise digital accelerometers in the industry. A yaw sensor measures car rotation to detect oversteer / understeer conditions.
- Configure channel name and logging rate (1, 5, 10, 20, 30, 50, 100Hz)
- Re-map accelerometer channels so the enclosure can be mounted in any orientation
Analog Input Channels (1 - 8)
Measure sensors for engine temperature, air intake temperature, suspension travel, boost pressure, oil pressure, and much more.
- Configure channel name and logging rate (1, 5, 10, 20, 30, 50, 100Hz)
- Map the input to real-world representations of pressure, temperature and so on using these 3 options:
- Raw Value
- Linear Scaling (simple)
- Mapped Value (using a interpolated table)
- Channel 8 is a dedicated channel for measuring battery voltage
Pulse Input channels (1 - 3)
Measure engine RPM, wheel speed, and any other pulse or frequency signal.
- Configure channel name and logging rate (1, 5, 10, 20, 30, 50, 100Hz)
- Configure the channel scaling so real-world values are logged, such as RPM, MPH, frequency, etc.
General Purpose Input / Output Channels
These channels are individually configurable for input or output (jumper configurable).
When configured as output, these can be used for activating accessories, such as video cameras (e.g. GoPro) , warning lights, relays, and more.
When configured as input, these can be used to read a switch, the state of a low speed sensor, and so on.
- Configure channel name and logging rate (1, 5, 10, 20, 30, 50, 100Hz)
- Set for input or output mode in software (also requires jumper setting)
Analog / Pulse output channels
The analog / pulse output channels can be used to provide a variable voltage or pulse for controlling other system or devices. This can be used to control external systems, override ECU settings
Analysis
Race Capture Pro's included analysis software, Race Analyzer, lets you import data from multiple sessions and compare them side by side, using a variety of charts, gauges and visualization tools.
Furthermore, Race Capture Pro records data in a simple comma-separated value (CSV) format, allowing you to load your data into a variety of other tools.
Expandability
Real Time Telemetry
In beta testing now is a dedicated cellular module that allows streaming of race car data right to the internet, allowing monitoring from the pits or anywhere else in the world. With just a pre-paid SIM card, race cars can now have a dedicated connection to the internet! Plans such as T-mobile offer unlimited data at $3 a day - $6 for an entire weekend of racing.
