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]; applies to all transmission types (M/T - manual and A/T - automatic)
selected gear will start showing correctly after all gears have been detected and calibrated successfully (Confidence percentage % highlighted in green color)
in case of M/T (manual) transmission, the calibration can be sped up by driving in each gear at steady speed uninterruptedly for at least 10 seconds then shifting up so the app can register a gear change, as demonstrated in the video (Note: the calibration dialog doesn't have to be open as the calibration is always running in the background)
in case of A/T (automatic) transmission, the calibration will eventually finish after certain period of time and driven distance, it's advised to just keep driving as per usual
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 or more 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 or less gears detected for M/T 5-speed gearbox), after adjusting press "reset" to restart the calibration
