COBB Accessport for Porsche 997.2 GT3 / GT3 RS

Calibrate the supported naturally aspirated 997.2 GT engine and monitor its operating data with an Accessport V3. Match the exact GT3 or RS software, particularly the separate 4.0-litre version.

Technical Details

• Application-specific device for the listed 997.2 GT3, RS and RS 4.0 manual engines.
• Stores the supported engine calibrations and records relevant operating channels.
• Choose the actual engine version and fuel rating; a GT3 map is not automatically an RS 4.0 file.
• Use a compatible PC or Mac with Accessport Manager for maps, logs and device updates.
• Before flashing, identify any existing third-party tune. COBB warns that writing over software other than original or COBB files can damage the ECU/TCU.

Use restrictions

Use only the current calibration approved for the exact application, fuel and hardware. Any CARB Executive Order coverage is limited to its listed vehicles and configurations; no blanket approval is asserted for all maps or modifications.

With over 20 years of parts experience, PMB Performance can help check the application. Share your VIN, ECU reference, intended fuel and installed hardware before ordering if the match is uncertain.
