Integrated Race Module and Data Logger for Supported aRacer Systems.
The aRacer Race Module 3 combines race module and logger functionality into one advanced expansion module for supported aRacer systems.
By integrating race module and logger functions, Race Module 3 helps reduce the number of devices on the CAN bus while also reducing wiring volume and overall system weight.
What It Is
A combined race-function expansion module and data logger designed for advanced tuning, testing, suspension setup, race analysis, and performance development applications.
Key Features
-
Integrated Race Module and Logger Functions – reduces CAN bus device count, wiring volume, and system weight
-
Real-Time External Sensor Reading via USB Power – external sensor signals can be read in real time when powered by USB
-
Suspension Zero Calibration Support – useful for on-vehicle suspension zero calibration
-
Selectable Logger Data Rates – supports 512 Hz, 128 Hz, and 32 Hz external sensor logging rates
-
Real-Time CAN Bus Data Transmission – external sensor data can be transmitted to the ECU in real time via CAN bus
-
SpeedTuning X Display and Recording – supported data can be displayed and recorded in SpeedTuning X
-
Improved Log File Access – new file format significantly improves data loading speed
-
Expanded Internal Memory – 50% capacity increase to 480 MB
-
Long-Duration Logging – supports approximately 7–24 hours of data logging depending on data content and setup
-
Real-Time Lap Time Gap Function – supported after Race Panel version update
External USB Functionality
-
External USB Storage Support – supports data logging to external USB storage
-
Up to 90 Minutes of Continuous USB Recording – useful for quick access to track data during race sessions
-
Fast Trackside Data Access – allows quicker data retrieval and review during racing and testing
-
Dual Recording – records simultaneously to internal memory and USB storage
Internal Memory and USB Recording
Race Module 3 records to both built-in memory and external USB storage where supported.
-
Internal Memory: optimized for long-duration logging
-
USB Storage: optimized for fast access and trackside analysis
This dual-recording setup provides a more complete logging solution for race teams, builders, tuners, and advanced users.
Data Access Performance
The updated file format significantly improves data loading speed. As a reference, a 30-minute log file may load in approximately 37–90 seconds, depending on data content.
