So unplugging the yaw sensor (deep under the passenger seat (as defined for LHD cars, I.e. the right seat), under the carpet/pad to the right, follow small wiring harness, best to put the seat all the way up and forward) unlocks full hoon mode: no traction or stability control, you keep ABS and AWD. I haven't noted any other detriment- reduced power mode, etc. From my research there shouldn't be any issues plugging/unplugging, the calibration in the brake controller is specific to the individual yaw sensor. Long term plan is to put a switch in the power to the yaw sensor and then have on/off capability.
