the model 3 drive unit inverters feature a PCB with both HV and LV circuits, the gate drivers, and logic. thus a simple replacement brain board is not possible. canbus control is complicated and requires use of tesla's diagnostics software for inverter pairing. this is a legal greyzone and not a fully opensource option. Instead a full fledged replacement board with gate drivers was designed to allow full lobotomization of elon, thus gaining full opensource control of the model 3/y drive units!
