These maps govern (For each profile) the input RPM threshold for changing up or down gears based on the users pedal position (Which correlates to load demand).
This map governs how much MPC pressure is required to hold the gear when given a certain load. The load column is rated in terms of gearbox load. Where 100% would be the max rating of the gearbox. For example, on a small 722.6, 100% load would be 330Nm.
This map governs how much current is needed for the MPC or SPC solenoid to create a requested pressure. The current changes as the ATF temperature increases due to the viscosity of the ATF changing at higher temperatures.
This map governs how much duty cycle (PWM) is required by the TCC solenoid to produce a certain pressure in the converter lockup clutch. As the value is 12bit, the max value 4096 correlates to fully on, and 0 correlates to fully off. Again, the PWM changes based on ATF temperature due to viscosity differences at different temperatures.
This map denotes how much pressure shall be sent to the to-be-applied clutch during a shift to fill the clutch drum up. Too much pressure here will cause a premature shift. Too little pressure will cause a flare or jerk shifting.
Eventually, the TCU will adapt this value on the fly to get smooth consistent shifts
This map denotes how long to hold the filling pressure of the clutch. This map changes based on ATF temperature due to viscocity changes in ATF.
Eventually, the TCU will adapt this value on the fly to get smooth consistent shifts
This map states how much additional MPC pressure to add to the current clutch during the fill phase. This can help with avoiding a flare situation due to a drop in MPC pressure during the prefill phase of the shift (As some pressure is diverted to the SPC line).
Eventually, the TCU will adapt this value on the fly to get smooth consistent shifts
These maps are the target shift time for the TCU to achieve when changing gears. If you want faster or slower gear changes, these maps should be edited.
This map is constantly overwritten by the Torque converter program as it adapts!
This map is used to store the pressure required by the torque converter to achieve a 'bite' on the torque converter clutch at lower loads.
