COBB Tuning Accessport V3 for Porsche 997.2 Carrera S/4S/GTS
The COBB Accessport V3 is the most powerful and versatile ECU tuning solution available for the Porsche 997.2 platform. Porsche’s factory ECU calibration is intentionally conservative; COBB’s OTS (off-the-shelf) maps unlock sharper throttle response, smoother power delivery, and meaningful gains in horsepower and torque. As you upgrade your 997.2 with bolt-on performance parts, the Accessport grows with your build—making it the last tuning device you’ll ever need.
Installation is simple: download your preferred COBB map, connect the Accessport to the OBD2 port, and flash the ECU in about 20 minutes. Your original Porsche factory tune is safely stored so you can revert to stock at any time.
Off-The-Shelf Maps & Power Gains
COBB's OTS mapping for the 997.2 Carrera S and GTS delivers noticeable gains in power and drivability across the rev range. Available maps include:
- Stage 0 v101
- Stage 1 91 v101
- Stage 1 93 v101
- Stage 1 100 v101
Stage 0 is the stock Porsche calibration. Stage 1 maps are designed for otherwise stock vehicles; aftermarket mufflers or cat-back exhaust systems are fully compatible and will not affect tuning.
Dyno testing of the Stage 1 91-octane and 93-octane maps shows consistent gains in both horsepower and torque throughout the entire powerband. The 100-octane file offers an additional 4–5 peak horsepower for track use or high-performance driving.
The Accessport V3 features a large full-color screen, customizable multi-gauge layouts, interchangeable faceplates, and real-time monitoring of up to six engine parameters. With room for 100 calibrations, this is the ultimate plug-and-play tuning tool for the 997.2.
