Defines % of absolute clutch pressure during prefill phase of shift procedure in function of GEAR x LOAD.
This is related to first phase of the shift while still off-going (currently driven) clutch is pressurized. On-going clutch is turned on with that pressure for defined PREFILL TIME period.
Too low value will cause flare/slip and eventually poor quality shift as shift pressure won’t match slipping scenario. Too high value will cause too big drivetrain preload / lock that can be recognized as car decelleration at beginning of the shift like the brake would be pressed a bit.
Editing per each gear is not mandatory and ODD / EVEN clutch pairing can be used as tuning method – this way adjust all ODD clutched with same values and all EVEN clutches with same values.
Pressure is directly related to torque.
