In releasing a product that has never before been offered, our Porsche Calibration experts created PDK calibrations that we felt would give the greatest performance impact as well as appeal to most enthusiast owners. While the specifics of the map for each vehicle may differ slightly, below is a general representation of what to expect when using one of three provided PDK OTS maps.

All supported vehicles will have the following maps to choose from:

• COBB Sport Map

• A nice mix between the factory Normal and Sport Drive Modes.

• COBB Aggressive Map

• More ideal for vehicles being used on track or during competition.

• COBB High Torque Aggressive

• All COBB Sport and COBB Aggressive features plus increased clutch pressures

Below we highlight features that are integrated into the PDK Off The Shelf Maps. For a complete list of changes made to the PDK OTS Maps please see the PDK Map Notes Page.

• INCREASED MINIMUM SHIFT POINTS

• The factory shift schedule is geared towards maximizing fuel economy in Normal mode. Our calibrators have increased the Minimum Shift Point for each individual gear, giving cars a more sport like feel during normal driving. This feature increases the lowest RPM at which the PDK will shift to the next gear in Normal and Sport drive modes.

• INCREASED AUTO SHIFT POINTS

• This feature increases the highest RPM at which the PDK will shift to the next gear in Normal, Sport, and Sport Plus drive modes.

  • COBB Sport does not increase the auto shift limit.

  • COBB Aggressive and COBB High Torque Aggressive increase the auto shift limit to a maximum of 7900RPM

• RACE START LITE

• This adds Race Start to Porsche Normal and Sport drive modes for all cars (including vehicles that do not have Sport Chrono). In COBB Sport, COBB Aggressive, and COBB High Torque Aggressive maps Race Start Lite is set at 5700RPM in Normal and Sport drive modes. Race Start in Sport Plus remains at the factory 6700RPM.

• INCREASED SHIFT FIRMNESS

• COBB Sport, COBB Aggressive, and COBB High Torque Aggressive maps raise the shift firmness to help reduce clutch slip.

• INCREASED CLUTCH PRESSURE

• COBB High Torque Aggressive maps raise the maximum clutch pressures to help reduce clutch slip after shifting. The COBB High Torque Aggressive map is typically used on vehicles that have an increased engine torque output of 50% or more over stock. If the COBB High Torque Aggressive map is flashed to the TCU a PDK Relearn must be completed when changing maps back to COBB Sport, COBB Aggressive, Simulated Stock, or when uninstalling. Failure to do so may result in less than desirable shifting and/or TCU errors. PDK Relearn instructions are located below.

• MINIMIZED CONTINUOUS CLUTCH SLIP

• COBB Sport, COBB Aggressive, and COBB High Torque Aggressive maps decrease the RPM at which the clutch is engaged in continuous slip, generally between 1000-2500RPM.
