This product is currently unavailable.
APR is pleased to present the ultimate transmission control unit (TCU) upgrade for the S6 and S7 DL501 DSG and S Tronic transmissions! APR’s TCU upgrade 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 enhance the driving experience especially when combined with APR’s performance engine software and hardware. 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.
