Product Details

The Accessport V3 is the world's best selling, most flexible ECU upgrade solution for Porsche. Unlock power hidden within the vehicle by replacing conservative factory settings with more aggressive calibrations. Upgrade forever with off-the-shelf (OTS) calibrations for most bolt-on modifications. The new in-cabin mountable Accessport V3 has a large, full color, higher resolution screen which allows you to monitor up to six parameters in real time. Fully customizable from the look (multiple bezel colors), layout (set up a race, street or dyno gauge cluster) and mounting options (choose from 1,000s of standard vehicle mounts). Of course, all of the great COBB tuning is included - with enough space for 100 calibrations. 

The v2.00 OTS Map revisions offer substantial improvements that benefit all facets of driving a Porsche 718 2.5L S Boxster/Cayman, and many of the improvements will be applicable to other 718 models in the future

  • Heat Management – At increased power levels and aggressive driving, the 718 has issues with managing heat. Our engineering team uncovered some factory tables that are unused in the stock tune. These new tables give us more control over the cooling system on the car, allowing the Accessport to make more power while managing heat efficiently. The same table discovery also provided access to safety modes that can actively protect the engine in the event that excessive heat is experienced in extreme scenarios.
  • Power and Control – Not only do the latest map revisions make more power, but they also do so more smoothly and consistently. Discovering and understanding new tables related to turbo and torque management along with a fundamental change in fuel injection characteristics greatly improved the overall power curve. As seen in the graphs above, torque peaks almost instantly and holds steady throughout the rpm range while also producing large horsepower gains under the curve all the way to redline.
  • High Load Transmission Smoothness – The engine and transmission are connected both literally and figuratively. Changes in engine management have an impact on transmission behavior even when no direct PDK adjustments are made. More precise airflow control in the latest maps proves that point as the cars now shift more smoothly and consistently in high load conditions. Ensuring that the car is predictable and responsive when pushed to its limits at the track.
