Live Race Car Telemetry: See the Data While the Car Is Still on Track
In motorsport, data is most valuable when it reaches the right people at the right time.
Data logging allows teams to review what happened after a session—but live telemetry gives the pit crew visibility of what is happening while the car is still on track.
The RACE Telemetry Modem Kit transmits live data from compatible Bosch Motorsport and MoTeC ECUs, displays and loggers directly from the race car to the pits over 4G LTE.
Instead of waiting for the car to return and downloading its logger, the team can monitor important performance and reliability data during the session.
From the Race Car to the Pits
The system uses two compact telemetry modems: one installed in the car and the other positioned with the pit crew.
The CAR modem connects to a compatible ECU, display or logger through its RS232 telemetry output. It then transmits the data over the 4G LTE cellular network to the PIT modem.
The PIT modem provides an RJ45 Ethernet connection for integration with the team’s pit-side telemetry setup.
This creates a live connection between the moving race car and the team monitoring it from the pits, provided suitable 4G coverage is available at the circuit or event location.
Why Live Telemetry Matters
Reviewing logged data after a session remains an important part of vehicle setup and development. However, it can only show the team what has already happened.
Live telemetry changes when that information becomes available.
Depending on the sensors and channels configured in the car, the pit crew may be able to monitor engine temperatures, pressures, electrical voltage, engine speed and other important vehicle data as it is generated.
This can help the team recognise changes or unusual readings sooner.
If a temperature begins climbing, a pressure reading starts falling or an electrical value becomes unstable, the crew may have an opportunity to investigate or call the driver into the pits before a developing issue becomes more serious.
Live information can also help teams make better-informed decisions during testing, qualifying and racing. Rather than relying only on radio feedback from the driver, the crew has objective vehicle data available at the same time.
Telemetry does not replace post-session analysis. It adds another layer of information that can be acted on while the car is still circulating.
A Compact Modem Designed for the Car
Space and weight are always important considerations when installing electronics in a race car.
The RACE CAR telemetry modem uses a compact aluminium enclosure that is well suited to motorsport installation. It operates from a 9–30 VDC power supply and is fitted with a robust Autosport connector for reliable integration into a professional race car wiring system.
A flat surface-mount antenna is also supplied for installation on the vehicle.
The compact RACE CAR telemetry modem features a robust Autosport connector for professional motorsport integration.
One Pit Modem Can Support Multiple Cars
The PIT modem receives the telemetry data and connects to the team’s pit-side equipment through Ethernet.
For teams running more than one vehicle, a single PIT modem can receive data streams from multiple cars. This makes the system particularly useful for multi-car operations that want to monitor their vehicles from one pit-side location.
Each car requires its own appropriate car-side telemetry setup, but the ability to use one PIT modem provides a more practical and scalable solution for larger teams.
The RACE PIT telemetry modem receives live vehicle data and provides an Ethernet connection for the team’s pit-side setup.
Bosch Motorsport and MoTeC Compatibility
The RACE Telemetry Modem Kit is suitable for a range of professional motorsport electronics with an appropriate telemetry or data output.
Compatible applications include:
- Bosch Motorsport ECUs with a suitable telemetry output
- Bosch Motorsport DDU10 and DDU11 displays
- MoTeC colour displays and enclosed loggers
- MoTeC C127 and L120 systems with the required MoTeC T2 telemetry upgrade
- Other compatible motorsport display and logger systems with a suitable RS232 telemetry output
Because the electronics and configuration can vary between race cars, compatibility should be confirmed for each application.
What Is Included in the Kit?
The RACE Telemetry Modem Kit is supplied with the main car-side and pit-side components required to establish the telemetry connection.
Each kit includes:
- One CAR telemetry modem
- One PIT telemetry modem
- One flat surface-mount car antenna
- One pit antenna
- One pit power supply
- One Ethernet communication cable
SIM cards and active cellular accounts are required for the telemetry system to operate over the mobile network.
RACE can supply the required SIM cards, assist with establishing the accounts and professionally configure the modem settings before the system is dispatched.
Installation and configuration support are also available.
Who Is the System For?
The RACE Telemetry Modem Kit is designed for motorsport teams that want to:
- Monitor important vehicle data during a session or race
- Identify developing performance or reliability issues sooner
- Give engineers and pit crew more information while the car is circulating
- Add live telemetry to an existing Bosch Motorsport or MoTeC system
- Monitor data from multiple cars at one pit-side location
- Receive professional setup and configuration support
Whether the car is being used for circuit racing, endurance events, rallying or testing and development, live telemetry can provide the team with a clearer picture of what is happening inside the vehicle.
Turn Logged Data into Live Information
A logger tells the story after the car returns.
Live telemetry allows the team to start reading that story while the car is still on track.
The RACE Telemetry Modem Kit provides a compact, professional solution for sending compatible Bosch Motorsport and MoTeC data from the race car directly to the pits—helping teams see important information sooner and make more informed decisions.
