# Indian Thunder Stroke: decoding motorcycle CAN signals

> Indian Thunder Stroke documents a listen-only J1939 CAN decoder for a 2017 Indian Springfield motorcycle, with ESP32-S3 firmware and an Android instrument cluster. Its findings map messages for tyre pressure and temperature, fault codes, controls and engine state, including measured PGN and byte positions; the hardware publishes decoded values over BLE.
