- Advanced parameterization — adjust controller parameters and configure new ECU units precisely
- Live data recording — record and analyze real-time sensor data and measurement values for deep diagnostics
- Error management — read and clear Diagnostic Trouble Codes (DTCs) with detailed fault descriptions
- Service functions — reset "Hot Shutdown" counters, perform "Splash Oil" calibrations and monitor emergency starts
