Car diagnostic port interface (ISO-9141) for a microcontroller

Speeduino ECU serial protocol simulator with a realistic engine model and full Speeduino protocol implementation. Streams live telemetry to tools like TunerStudio via UART or WiFi TCP serial. Runs on Arduino, ESP32, and ESP8266 for testing dashboards, loggers, and ECU integrations without real hardware.

This project features an engine control unit (ECU) for a gas turbine, built on the ESP32 platform. The code is developed using the Arduino IDE and leverages readily available libraries for ease of integration and development. The repository also includes optional code for a turbine engine instrument cluster, designed to run on a separate ESP32.
