Shift Schedules Adjustment

Adjustments to shift schedules can be done in using a few different methods, some more indepth than other, in this example a simple accel pedal axis and shift RPM changes were made in Drive mode, very few changes were made to ECU and Sport schedules as there are deemed to be OK.

...

Downshift Schedule (ALT Dive & ECO) for all Downshifts (6 → 1)

  • The Data and axis of these maps has been adjusted to achieve a slightly higher accel pedal value for the same downshift limit so that the car shifts downshifts a little earlier. More changes have been made to the drive maps as the ECO and Sport schedules are usually deemed OK.

...

Upshift Schedule

  • The Data and axis of these maps has been adjusted to achieve a slightly higher accel pedal value for the same downshift limit so that the car shifts downshifts a little earlier. More changes have been made to the drive maps as the ECO and Sport schedules are usually deemed OK.

...

Max Nominal Gradient for Downshifts in TT

  • Increase to allow for shifts whenever the TripTronic shifter is pulled

...

Upshift Inhibit Torque Threshold

  • Increased to 6000 to allow high torque upshift’s

...

Max Nominal Gradient for Downshifts in TT

  • RPM gradient set to 7500RPM/sec to increase the range and speed of the shift when triggered by paddle pressing

Multiple Downshift & Upshift Suppression Time

...

Sadly ProECU doesn’t currently handle arbitrary text in map Axis value so the axis of the shift maps are currently numbered 1 to 21

COBB have a very good sheet on a different method to set up the shift schedules, you can read their Shift schedule documentation here.
