Open the software, select the correct COM port, and choose your specific ECU profile.
Apps associated with this niche allow you to customize a fully digital dashboard on your phone or tablet. You can choose neon styles, retro pixel designs, or minimalist layouts. If you mount your phone on the windshield, it acts exactly like a premium Head-Up Display found in luxury cars.
For older Delphi MT05 ECUs, a cheap (featuring the FTDI FT232RL chip) is highly recommended. Hud Ecu Hacker

A clear example of illegal ECU modification is A case in China illustrates this vividly. A person named Zhang was sentenced to three months of jail time (suspended) for using a DTS diesel‑vehicle decoder to modify ECU parameters on multiple diesel trucks. Zhang manipulated values such as the "urea injection temperature max/min" to disable the vehicle's emission control systems, allowing the trucks to run without using diesel exhaust fluid (DEF) and illegally bypass environmental regulations. This not only caused excessive pollutant emissions but also disrupted public order and severely harmed the environment. Open the software, select the correct COM port,
Always ensure you have a backup of your original ECU calibration, and use the software in a controlled, safe environment. Conclusion
: The software’s core logic is stored in an XML "parameter file," meaning users can adapt it to scan almost any ECU in the world by defining their own commands and responses. If you mount your phone on the windshield,
Record live sensor data during a test drive to analyze performance bottlenecks or intermittent faults later.
: If using a serial adapter, ensure the correct COM port is selected in the settings.
