If mkx is your primary concern, that makes things much easier. You could bypass the stock pcb completely and use forced ps3 mode until you get a better solution worked out.
I suppose a more important starting point would be to ask if you have a hitbox layout panel for the TE2, or a means to acquire one. If not, you would probably be better off selling the TE2 while it’s hot and paying a modder to fix up your current hitbox (assuming you already have one).
Test the te2 for socd in windows per my YouTube reply
