COBB Accessport for Porsche 991 GT3 / RS with PDK Flashing

Pair supported GT3 engine calibration with the dedicated PDK map functions on the listed 991 generations. This package excludes manual-transmission cars and requires the correct GT-specific ECU/TCU software.

Technical Details

• Dedicated GT PDK package adds supported transmission maps to the ECU license.
• Use only the listed 991.1/991.2 GT3/RS PDK configurations; manual GT3 is excluded.
• Map-dependent shift behavior and transmission data are available through the supported device/software.
• Use a compatible PC or Mac with Accessport Manager for maps, logs and device updates.
• Unknown non-OEM/non-COBB software must be resolved before installation; COBB specifically warns of control-unit damage when flashing over an incompatible tune.
