The COBB Stage 1 Power Package with DSG Flashing is the ultimate ECU and TCU tuning solution for the Volkswagen GTI Mk7/Mk7.5 and Jetta GLI (A7). At the center of this package is the Accessport V3, the worlds most flexible and user-friendly ECU tuning device. With a large, full-color, high-resolution display, it doubles as a customizable gauge cluster capable of monitoring up to six parameters in real time.

This version of the Accessport supports flashing for both the Engine Control Unit (ECU) and DSG Transmission Control Unit (TCU). Off-The-Shelf ECU maps are included for common bolt-on modifications, while DSG maps deliver optimized transmission behavior to suit a wide range of driving styles. Options include COBB Aggressive, Sport, OEM+, and Simulated Stock, as well as IS38-specific calibrations for maximum torque delivery.

The Accessport stores up to 100 maps, allows you to switch calibrations on the fly, logs performance data, clears trouble codes, and even measures performance metrics like 060 mph and quarter-mile times. Features like Adjustable Traction Control, Flat Foot Shifting, and Launch Control add even more flexibility for both track and street use.

To complement the Accessport, the package includes a COBB High Flow Filter, designed with woven cotton and metal mesh to maximize airflow while maintaining filtration efficiency. Pre-oiled and washable, this reusable filter is a direct drop-in replacement that improves efficiency and extends service life.

Note: Live monitoring and datalogging of DSG parameters is currently supported only on 6-speed transmissions. Not compatible with GPF-equipped vehicles.
