Summary

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).

Added Files:

Added Ecu Emulator for testing
Added Torque app PID.csv
Wokwi PCB Design
My custom PCB build
L9637d pinout
Realdash XML (Plug and play)
racechrono.rcz file

Added OLED Support:

0.96" I2C

Supported PIDs:

MCU Uptime seconds (Wraps around after 65,536 18h.20m)

Requirements:

To build this project, you will need the following components:

L9637D
510 pull-up resistor Not needed for RX
Level conversion components

Additional Information:

It's possible to pozi-tap the loom for other sensor data not sent via the k-line.
