The APR TCU Upgrade enhances the operation of the DSG transmission in all aspects. Performance and comfort is greatly improved in both Drive Mode and Sport Mode In Drive Mode gear change upshift and downshift points occur based on engine load and throttle position, rather than hard set points for a more natural feel. Under part throttle driving, the transmission will stay in the current gear until the appropriate moment necessary to shift, rather than jumping to higher gears too quickly. In Sport mode extremely fast gear changes are possible as the wide-open throttle shift times are reduced. APR has taken a two-stage approach to wide-open throttle operation as well. Shift points are optimized to deliver the fastest acceleration possible under wide-open throttle by following the torque curve of each available stage. However, with the pedal pressed far enough to hold the kickdown switch, shifts points override the torque curve and now occur at the maximum engine RPM! Finally, a user definable launch control system is enabled which allows a 3 step launch RPM based on pedal position.
