Ford finally managed to steal my old travel charger and swap for one of the new units with the thermal sensor in the NEMA plug. Seems it has a PIC microcontroller running things.
I *may* try to reverse engineer the board and load my own code to a similar PIC to have the unit offer 16A - even if I have to just write my own from scratch. Along the same lines, the vehicle was registering the pilot duty cycle as 19-19.5% when running it on 240V, which translates to 11.4 and 11.7A. It seems my car consistently underestimates the pilot like this, which could explain why I've never actually seen 30A of draw from my wall charger.
I could even see the "available charger power" reading go up and down on ForScan when the pilot duty cycle changed. I'm curious to see if I can get it to underestimate the pilot value instead or even get it to underestimate the current draw by just a little to compensate.
