Overall impression:
In the second TCU tune minor changes are noticeable in a subset of the shift cases.
Recorded Data:
The chart below shows the engine speed at which the TCU downshifts the transmission when the car is coasting, meaning 0 pedal input.
Blue dots are recorded data, orange dots are suggested shift points.
The chart below shows the engine speed that a shift from 1 to 2 takes place for a given pedal input.
Blue dots are tune Version 1, orange dots are tune Version 2. The red line is the suggested behavior.
The next chart shows the engine speed that a shift from 2 to 3 takes place for a given pedal input. Blue dots are tune Version 1, orange dots are tune Version 2. The red line is the suggested behavior.
The next chart shows the engine speed that a shift from 3 to 4 takes place for a given pedal input. Blue dots are tune Version 1, orange dots are tune Version 2. The red line is the suggested behavior. 
The next chart shows the engine speed that a shift from 4 to 5 takes place for a given pedal input. Blue dots are tune Version 1, orange dots are tune Version 2. The red line is the suggested behavior. 
The next chart shows the engine speed that a shift from 5 to 6 takes place for a given pedal input. Blue dots are tune Version 1, orange dots are tune Version 2. The red line is the suggested behavior. 
The next series of charts show the engine speed that a “kickdown” downshift, occurring with moderate to heavy pedal input, takes place.
The first chart shows the “kickdown” engine speed for a given pedal input from 6 to 5. Blue dots are tune Version 1, orange dots are tune Version 2. The red line is the suggested behavior. 
The chart below shows the “kickdown” engine speed for a given pedal input from 5 to 4. Blue dots are tune Version 1, orange dots are tune Version 2. The red line is the suggested behavior.
The final chart shows the “kickdown” engine speed for a given pedal input from 4 to 3. Blue dots are tune Version 1, orange dots are tune Version 2.
