The Calibrations screen, opened from Settings, corrects readings that arrive different from the car's dashboard, sets alert thresholds and gathers the settings that trade precision for performance. It is split into the Sensors, TPMS, Performance and Default sensors sections.
Correct the speed
Speed correction makes up for the difference between the speed read over OBD and the one shown on the car's dashboard. The correction is applied to the reading, so every screen and feature that uses speed reflects it automatically.
Overspeed threshold is the value above which the Safe Score counts a speeding event. The default is 120 km/h.
Tune the sensor check
Alternative detection of supported sensors tests the sensors one by one instead of trusting the list the ECU reports, because some ECUs publish that list incorrectly. Turn it on only if sensors the car has are missing, because every connection becomes noticeably longer.
Group identical probes asks the vehicle each distinct question only once during sensor discovery, which makes it far faster. Turn it off only to compare results.
On Nissan and Infiniti cars, Manufacturer sensor list (Nissan/Infiniti) asks the ECU which manufacturer sensors it serves, 32 at a time, and Open and close a diagnostic session serves modules that only answer that list inside a session, returning the module to normal reading afterwards.
Set the TPMS thresholds
In the TPMS section, Minimum pressure and Maximum pressure set the alert thresholds: tires below the minimum appear in red on the Tire pressure screen, and above the maximum, in amber.
Tune the performance
Live Data Chart Refresh Interval sets how often the Individual and Integrated tabs are redrawn; higher values keep scrolling lighter in the rest of the app. Panel Refresh Interval does the same for the Panel: lower values make the animation smoother, and higher ones cut processor use.
Priority sensor reading sets the reading rate of the priority sensors, which can be read several times a second. Zero keeps the reading continuous, and speed and RPM stay continuous at any value. ECU tolerance before reconnecting sets how many standard sensors may fail in a row before the app checks whether the ECU is still answering; higher values are more forgiving with slow adapters.
Choose the sensors recorded per trip
Default sensors lists the sensors recorded at the end of every trip and available in the playback forever. The other readings stay available for a number of hours after the trip ends, shown on the screen itself. Add sensor includes other sensors in the permanent recording.
- Speed correction
- Makes up for the difference between the OBD speed and the dashboard one. Applied to the reading, it holds for every screen.
- Overspeed threshold
- Above it the Safe Score counts an event. 120 km/h by default.
- Manufacturer sensor list (Nissan/Infiniti)
- Asks the ECU which manufacturer sensors it serves, 32 at a time. It speeds the first check up on those makes.
- Open and close a diagnostic session
- For modules that only answer the manufacturer list inside a diagnostic session.
- Alternative detection of supported sensors
- Tests the sensors one by one instead of trusting the ECU's list. It makes every connection longer.
- Group identical probes
- Asks the vehicle each question only once during discovery. Turn it off only to compare results.
- Minimum pressure and Maximum pressure
- The TPMS alert thresholds: red below the minimum, amber above the maximum.
- Live Data Chart Refresh Interval
- How often the Individual and Integrated tabs are redrawn.
- Panel Refresh Interval
- How often the Panel updates. Lower is smoother; higher uses less processor.
- Priority sensor reading
- The reading rate of the priority sensors. Zero keeps the reading continuous; speed and RPM stay continuous.
- ECU tolerance before reconnecting
- How many standard sensors may fail in a row before the app checks the ECU.
- Default sensors
- The sensors recorded at the end of every trip. Add sensor includes others in the permanent recording.
