So I have a Samsung tablet updated with the latest Android and patches available, an OBDLink MX+ with the latest firmware, the most recent TuneECU version (updated it a couple of days ago) and the option is there for me. Have you made sure if you’re using a phone with less screen real estate that it’s not just off the screen and you have to scroll down? Otherwise as other folk said in the other thread, reach out to TomTom or Alain. They are both fairly responsive.
FYI this was just going down to the bike and turning on the ignition (one click up, one click down) and without starting or warming the engine… Just to clarify further, make sure you scroll to the “dashboard” page rather than the map page, click into ECU, then Tests&Adjustments, then Adjustments.
