Yamaha DataLogger

ESP32 s3 BLE Yamaha Datalogger
Description:

The Yamaha DataLogger is an ESP32-S3 based device designed to convert k-line data into Canbus ODB2 standard, using ELM327 emulation. Enabling compatibility with apps like RaceChrono, Realdash, and Torque.

• Displays PIDS via OLED screen.
• Handles automatic gear ratio tuning via BLE Serial "gear learn", (using gipro gear indicators learn function approach).
