The FCSP does have that option but I haven’t tried as it’s working great with the lightning on 80a (after it had problems the first few weeks I don’t want to mess it up lol).
I talked to @FlasherZ they said it worked with a model X, I sent follow up questions and they never replied unfortunately. I have dremeled a j1772 adapter, it fits in the FCSP perfectly and locks into the Tesla model Y perfect. It recognizes 48a max and all but when you go to charge the FCSP...
Hasn’t overheated in a couple weeks for me since temps have gone down which is nice but we will see again next summer, not sure if the firmware or just the temps has helped. I have tried to charge my model Y with a couple different adapters but it’s no go, throws an error in the Tesla every time...
