    Do you have to do this every time you start the vehicle?

    Sweet info, thanks for the details! Can we check any other diagnostics in this menu? For example boost pressure, A/F ratio, etc...?

    My below answers are based on how this works with BMWs....my Supra is lost in transport, so I am unable to verify my answers.

    Yes

    See above answer


    There is a lot of items it can display. On my last BMWs I mainly used it to monitor coolant temps.

    Others that I recall: battery voltage, needle sweep, light check, true speed, digital rpm....


    Googling or YouTubing “BMW secret menu” should reveal a list of items that are available on BMW models....can’t confirm all of those will work on the Supra, but I would say that there would be a good likelihood that they do.

    The oil temp of 111C at idle in the video is a bit of worry

    Unfortunately, no. The temp data is really the only thing I found useful other than Dyno mode.

    The car runs pretty hot around town anyways from what I've seen. Around 220F coolant temps and 230F oil temps. Neither of which are much of a concern to me. Once you start to drive the car a little harder, the coolant temps actually drop (likely due to electric water pump) and the oil temps stabilize.

    I'll have some track data regarding temps in the next couple weeks.
