APR is pleased to present the ultimate transmission control unit (TCU) upgrade for the DL501 Gen 1, Gen 1.5 and Gen 2 S Tronic transmissions! APR's TCU upgrade is available for 3.0 TFSI platform vehicles and is conveniently flashed to the vehicle's TCU through the OBD-II port with user definable options selectable at the time of install.
APR's TCU upgrade goes beyond the overly simplistic norm of raising a few limiters, and offers a wide gamut of changes designed to completely enhance the driving experience. With an in-depth knowledge of the transmission's inner workings and control strategies, APR's engineers have improved many aspects of the transmission from accelerative performance to daily drivability, while also incorporating new features including several typically reserved for higher-end Audi Quattro GmbH RS models.
Depending on the driving scenario, APR's calibration experts have created multiple operating modes designed to deliver ideal performance for the given driving condition. When using launch control, the transmission enters a maximum acceleration mode designed to provide the fastest possible acceleration through a heightened application of torque, optimized shift points and shift strategies among other performance related enhancements. Under blistering, near wide-open throttle, the transmission enters a different state of performance with shift maps optimized for power delivery on vehicles with modified engine software. Manual and Tiptronic mode are tailored to the driver's desired auto up/down shift preferences at the time of install include several features to enable quicker paddle response times and faster upshifts on Gen 2/B8.5 models. Finally under part-throttle daily-driving in both Drive and Sport mode, the transmission remains calm and smooth. Common clunks and driver annoyances are addressed and the transmission comfortably responds to the driver's input without constantly and aggressively seeking the highest gear possible.
