Well, you asked for in-game calibration (nvram) not emulator calibration. For emulator calibration i use different profiles for Racing Games (works for Ace Driver, MotoGP and Wangan Midnight) and for Fighting Games (works for all Tekken games, but i still not tested on Soul Calibur), i know you use Chinese (Mandarin ?) language, but i use google translator when trying to help others here because my native language is Portuguese.
The localization of Steering, Accel (or GAS) pedal and Brake pedal are in these yellow marked inputs. So i set the config to Right Trigger (R2 in PS Controller) and Left Trigger (L2 in PS Controller).
Remember to set the opposite axis to another key so it not conflicts in-game command.
This is my Tekken diagram:
The icons of PS2 controller i placed are equivalent to their commands on Console port.
