APR's TCU upgrades for the Porsche 911 (991.2) 3.0T/3.8T 7-speed PDK platforms are here! The PDK is an amazing transmission on its own, but our engineers have made it even better, especially when combined with our ECU upgrades. We've totally reoptimized the transmission allowing it to hold more torque, accelerate more quickly, and drive more smoothly, all while adding more features to greatly improve the driving experience! The software and calibration engineering teams at APR spent the better part of a year fully testing, tuning, and understanding the PDK before ever releasing PDK transmission tuning to the public. This included countless trips to various tracks under grueling conditions to ensure the changes we made were truly better, but also reliable. The following are a list of features, improvements, and conditions improved upon with our tuning. Features: Maximized transmission torque capacity Increased clutch pressure and current Optimized wide open throttle shift points Clutch kick enabled (Configurable behavior) Creep mode disabled (Configurable behavior) Optimized launch control strategies (Configurable ECU behavior) Launch control enabled in more modes, without Sport Chrono Optimized shift strategies High lateral G-force shift strategy fix Flash counter does not increase with each flash Free lifetime updates Direct OBDII port flash (No TCU removal) 30 day money back guarantee Find your boxcode and revision Performance notes: When updating the TCU, always check for and update to the latest ECU version, if available. We have only validated our TCU upgrades while using our ECU upgrades. When not using both in combination, various behaviors and features may not be predictable or as described. Even on completely new and stock vehicles the PDK exhibits inconsistencies during launch control. Our TCU upgrade does as much as physically possible to minimize this, but simply put, the PDK, on a stock or tuned vehicle, may not always launch perfectly. We recommend ensuring the gearbox temperature is at least 60c to help limit shifting irregularities, especially on the first to second gear shift during launch control. Please Note: Each vehicle's year, make, and model may have multiple factory engine or transmission controller software part numbers, known as box codes, each with unique revisions. Manufacturers periodically release software updates that alter this information, which can only be determined by scanning the controller and is not publicly provided. Due to the variety of codes, some stages, octane levels, features, or options may not be available for specific codes. Therefore, our website provides a general guide based on general info such as Year, Make, and Model. Our system allows you to request unavailable software, and we offer a 30-day money-back guarantee if you're not satisfied. This part is legal for sale or use on Emissions Controlled Vehicles, Uncontrolled (Non-Emissions Controlled) Vehicles, and Racing Use Only Vehicles because it does not affect vehicle emissions and is not covered by emissions regulations.
