Another consideration: my eMMC replacement took three days. This was around October 2020. I, like others, subsequently went to MCU2 as I’d already had HW3 installed. I was afraid that if I stayed with MCU1, I’d end up with less than FSD operations.
It's obvious that FSD will NOT work properly with MCU1/HW3. Don't be "afraid", demand what you paid for.
