Open APP SETTINGS from the home page, then Unit and Values. Here you set speed units, distance units, vehicle speed source, temperature units, power units, time format, pressure and weight units, date format and the fuel consumption display.
Set the vehicle speed source deliberately. It decides whether displayed speed comes from the ECU, from GPS, or from wheel speed, and the three will not always agree, particularly on a vehicle with non standard tires.
| Setting | Common choice |
| Speed units | km/h for UAE, mph for export |
| Distance units | km |
| Temperature units | °C |
| Pressure units | bar or psi, match your tuner’s convention |
| Time format | 24 hour |
| Vehicle speed source | ECU, GPS or wheel speed |
