ECU Map Notes:


All maps are designed for vehicles with stock clutches.  If you have upgraded clutches it's recommended to get a custom tune   

Shift Schedules: 

  • Enhanced shift schedules during more aggressive driving conditions (higher throttle input)
  • Normal driving conditions retain stock shift schedule.

PDK Relearn

  • A step-by-step guide on how to perform this procedure with the Accessport can be found here: How To: Perform PDK Clutch Re-Learn      
  • Over time clutches can wear and the thickness can decrease.  Performing a PDK relearn will help the PDK verify clutch thickness and position.  This is particularly useful after a clutch replacement or in cars with higher mileage.
  • The adaption process an be quite loud and the car may clunk or lurch somewhat violently.  This is normal during the adaption process.

Closing Warnings and Precautions:

  • Use of inappropriate calibration/modification combinations may promote transmission damage.
  • Some higher mileage PDK cars may have driveability problems that may be exacerbated by flashing the PDK, most notably a shudder when starting from a stop at low throttle in 1st gear or reverse.  In most cases a simple PDK fluid service is all that is needed to remedy the issue, however the issue may be more indicative of a failing valve body.  A PDK Relearn will unfortunately not fix this issue.  We suggest doing a PDK fluid service before installing the PDK flash if you are still running original fluid regardless of milage.
