Project Type TCU Stage 3 20bar
Description

Stage 3 for gearbox.

  • Up to 1100 Nm torque handling capacity
  • 20+ bar clutch pressure
  • 6800 RPM upshift target
  • Faster upshifts
  • Faster downshifts
  • Faster synchronization
  • Optimized downshift points and lockouts
  • Corrected shift delay calibration - gearbox shifts at the actual RPM specified in the shift maps
  • Disabled OEM gear simulation via clutch slip
  • Reduced torque gradient damping (torque can ramp up faster)
  • Increased launch control RPM
  • Removed launch control count limiter
  • Increased launch control timeout to 30 seconds

NB!

  1. You must use MDNORM, KFMIRL and KFMIOP from the provided example ECU file in your ECU calibration. If you do not do this the gearbox will not shift correctly. The load goes up to 240, which is enough for 1100 Nm.
  2. You must make a full write of the gearbox. If you write only the calibration, then all modifications will not be written, the gearbox will never exceed 16 bar clutch pressure.
  3. After the write you must perform "calibration of clutch valves" in basic settings with VCDS. If you do not perform this basic setting, the gearbox will never exceed 16 bar clutch pressure. During the basic settings measure the pressure, it should visit 20+ bar target during the calibration on both clutches.
  4. After calibration of clutch valves is complete you must perform "adaptation of clutch valve kiss points" in basic settings with VCDS. Other adaptations/basic settings are not needed.
