Real-time Tuning and Datalogging: A Powerful Combination
The Hondata s300 v3 excels in real-time tuning. Calibrations and changes can be uploaded to the ECU in a mere two seconds for a full calibration, and even faster for minor adjustments – all while the engine is running. This eliminates downtime and allows for immediate feedback during tuning sessions. The SManager software reflects changes instantly, providing a dynamic and efficient tuning experience. Forget about burning ROMs or opening the ECU; all you need is a laptop with a USB port or Bluetooth.
Datalogging is equally advanced. Record data directly to your laptop or mobile device via USB or Bluetooth using SManager software. Visualize, graph, and save ECU sensor data for detailed analysis. Furthermore, the s300 v3 features onboard flash memory for standalone datalogging. Record up to 120 minutes of data without a laptop, triggered by an external switch or specific engine conditions – perfect for capturing data during track runs or dyno sessions.
