I have a HPWC installed on a 60 amp breaker charging my car at 48 amps, usually around 36 mi/hr (2013 P85 w/ dual chargers). After the last software update I received about a week ago, the car suddenly only charges at 40 amps, 30 mi/hr). I changed no settings. The car shows I have it set at 48 amp, but is only charging at 40 (so the display 30 mi/hr, 245v, 40/48a). What would cause the drop in charging rate? I cant seem to figure out how to get it to charge at 48 amps again. And yes, I've reset the car, triple checked the settings, etc. Anyone have any ideas?

I didn't think of that, but thats a possibility. I'll have to plug into another charger and see what happens.
I did double check the rotary switch on the charger and it is properly set.

Yeah, that sounds suspiciously like a firmware or hardware issue with one of your two chargers.
You sure you can’t hit the plus button while charging to jack it up to 48 again? I thought the first number was what you had the limit set to and the second was for what the upper limit actually is? A friend had this issue. They did not realize it was settable and it had gotten bumped.
