    For those who may not know (I didn't) here is the message you'll see on the touch screen if you try to install a firmware update while supercharging.

    It makes sense. The car is basically a brick while the update is ongoing and the speed of charge and cooling systems are closely monitored by the car's computers. BTW, they usually say 1:40 for an update, but I don't think I have seen one more than 30 minutes.

    But of course the onboard chargers must be autonomous (sorry) enough to be able to handle AC charging while updating because usually you are plugged in to home power when updating.

    Interesting note about supercharging, don't think we've seen it before!

    You will get that notice so as to not block a supercharger for the duration of your update which can be UP to 1:40. However, just as an FYI, the car will not charge at all while an update is in progress, supercharger or regular charger. If you notice when an update starts you will hear all kinds of clicks and sounds, that is the car preparing to update and that includes disabling charging. If you are ever charging at home and start an update your charging will be interrupted and restart once the update is complete.

    Duh! Would you think you could use your computer while it's installing an operating system update? Even opening a door can cause a problem with an update. They're best done overnight, when you're away from the car and aren't tempted to "check on it". That's why the default installation time is set for the middle of the night.
