APR TCU Software DQ250 S3 8P/MK5/MK6 GTI/R

APR is pleased to present the ultimate transmission control unit (TCU) upgrade for the DQ250 Exx & Fxx DSG and S tronic transmissions! APR’s TCU upgrade is available in engine and power level specific variations and is conveniently flashed to the vehicle’s factory TCU through the OBD-II port. APR’s DirectPort Programming Suite allows the end user to customize the TCU upgrade to their individual needs.

APR’s TCU upgrade enhances the driving experience by incorporating many of the same features typically reserved for high-end Audi Quattro GmbH RS models. Under blistering, wide-open throttle acceleration, the transmission shifts even more quickly than before with a higher rev limit. However, during normal, day-to-day driving, the TCU Upgrade delivers a smooth, yet responsive and refined driving experience.

APR’s DirectPort programming suite allows users to custom tailor the TCU upgrade to their needs at the time of installation. Users are given the following options, which they may change at an APR dealer at any time:

• User definable APR pre-optimized shift patterns based on current stage of engine performance
• User definable launch control RPM
• User definable manual mode max RPM
• User definable manual mode automatic upshift on or off
• User definable manual mode automatic downshift on or off (Kickdown switch)

Drive Mode Characteristics: Drive mode’s performance and comfort is greatly improved based upon the current stage of engine performance. Gear change upshift and downshift points occur based on engine load and throttle position, rather than hard set points, and as such occur more smoothly and less abruptly.

Launch Control: APR’s TCU upgrade enables launch control on all vehicles. At the time of installation, the user is able to select their desired launch RPM, as they see fit! Launch control activates quickly, with a wider operating window, by limiting some of the stubborn activation criteria some models face during activation.

Gear Display Indicator: APR’s TCU upgrade enables the gear display indicator for Drive and Sport mode in the vehicle's multi function display.

Torque Limits: APR does not charge extra to "raise the limits." Raising the limits does not increase performance and does not increase the transmission’s ability to hold more torque. The maximum torque limiters are simply removed, allowing customers unrestricted operation.

Manual Mode Characteristics: At the time of installation, the user is able to select several options that change the behaviour of manual mode. The user has the ability to enable or disable either the manual mode automatic kickdown switch for automatic downshifts as well as the automatic upshift that occurs at redline. For safety and acceleration, APR’s engineers kept the automatic upshift present in first gear.

DSG Temperature Management: Temperature management is an important part of the DQ250 transmission. While some software may simply remove temperature protection routines all together and claim increased cooling performance, APR’s TCU upgrade only allows the maximum safe temperature levels before intervention.
