Sorry if my explanation was rather cryptic
, I used the face buttons, circle for gas, triangle for brake, cross for e brake, square for reverse. L1 for shift down, R1 for shift up, steering with left analog, right analog is only for left / right view. Analog stick are the same on all PS2 or PS3 controller, the difference are in the face buttons and the D pad.
My DS2 pad uses USB converter, it also has been modded, I added a piece of tissue paper between the rear casing and the electronic board, then I also replaced the rubber pad for the face buttons and as well as D pad plastic holder inside. I took them from other broken DS2 internals.
I have 2 other DS2, they have different sensitivity than my DS3. What I am using now is perfect stick for my preference, it took at least 3 times the pressure of DS3 to full throttle and brake on the face buttons. If you saw my video somewhere here, I could apply any amount of percentage in brake and throttle quite easily without any trouble.
