Gearbox calibration

  • this tool is available in the app toolbox but can be also opened directly by tapping the [N...5] selected gear indication
  • calibration is fully autonomous, gears are detected by observing ratios between actual engine speed (SP-REVS) and vehicle speed (SP-VSS) [rpm/kph]
  • selected gear will start showing correctly after all gears have been detected and calibrated successfully (Confidence percentage % highlighted in green color)
  • you can speed up the calibration by driving in each gear at steady speed uninterruptedly for at least 10 seconds then shift up so the app can register a gear change, as demonstrated in the video (Note: you don't need to have the calibration dialog open as the calibration is always running in the background)
  • if your gears are not showing correctly or the indication is stuck on "Calibrating" open the calibration dialog and check for gears with question mark ? highlighted in "red color", drive your car in the highlighted gear to calibrate it for at least 10 seconds, in case you don't see any highlighted gear, just drive in all gears for at least 10 seconds, starting from the 1st gear (Note: lower gears have higher ratio e.g.: Gear 1 (~150)... Gear 5 (~30))
  • a falsely detected gear can be manually removed by long-touching the row with the gear and confirming removal in the confirmation dialog window
  • detection range:
    • set wider range if the number of detected gears is higher than actual count (e.g. 5 gears detected for A/T 4-speed gearbox) or the algorithm detects false gears frequently (highlighted in red color), after adjusting press "reset" to restart the calibration or remove the false gears manually
    • set narrow range if the number of detected gears is lower than actual count (e.g. 4 gears detected for M/T 5-speed gearbox), after adjusting press "reset" to restart the calibration
