Modern Yamaha vehicles—ranging from motorcycles (YZF-R1, MT-09) to outboard motors (F115, LF250)—incorporate electronic control units (ECUs) that require proprietary diagnostic software for fault code reading, sensor calibration, and actuator testing. The (YDT) software enables communication between a Windows-based PC and the vehicle’s ECU via a dedicated interface cable (e.g., YDIS, YDT-01). However, obtaining legitimate software remains problematic for independent mechanics and enthusiasts. This paper addresses the following research questions:
