This behavior (bug?) doesn't seem to be related to the 3.0 upgrade. My 2.0 (original battery) is manually set for 24 amps charging. It's plugged in right now (2nd generation "mobile connector 240", 14-50 pigtail), not charging, and the main screen properly shows "0/24A". Went to the charging menu. 15 amps is the highest offered. Moderately confused...
What are you using for an EVSE? I'm guessing the bug is in the UMC, and that the pilot signal to the car is incorrect when not charging (signaling a 120v outlet instead of the 240v it really has). When the car is charging the UMC's limit of 40 amps is seen and honored. Seems that the car gives us the benefit of the doubt when not plugged in at all, as all settings up to 70 amps are offered in that case.
@hcsharp can probably correct me on all this... Am I close?
