Can the dyno communicate with the vehicle and read live data via OBD?

Yes. The dyno software supports OBD-II communication. You can connect a compatible OBD interface (like ELM327) via USB or Bluetooth to read real-time vehicle data such as RPM, throttle position, coolant temperature, and more — directly on the dyno screen.

Note: Make sure your OBD device is properly configured and supported by the dyno software.
