APR DQ381 7-Speed DSG and S Tronic TCU Upgrade

Transmission

APR is pleased to present the ultimate Transmission Control Unit (TCU) Upgrade for the DQ381 7-Speed DSG / S-Tronic Transmission!

APR’s TCU Upgrade dramatically improves upon the DQ381 transmission’s function, drivability, and performance through a myriad of enhancement and custom features. Normal daily driving is smoother as we’ve improved upon the normal quirks and complaints associated with the driving experience. Sporty driving is far more capable with increased torque capacity, clamping pressure, faster shifting times, more capable launch control, and more, handily shaving .2 seconds off our Stage 2 S3's quarter mile time! Both are optimized to deliver faster acceleration by matching the power output delivered by our ECU Upgrade. This all comes with customizable features you can choose while flashing the TCU to personalize the transmission to your desire! Lastly the software loads to the factory TCU through the OBD-II port, resulting in a clean and headache-free install.

Feature List

icon

Optimized part throttle drive and sport maps

At lower throttle input, the system doesn’t race towards the highest gear. In doing so, we keep the turbo spooled between shifts for a more enjoyable driving experience.

icon

Optimized wide open throttle drive and sport maps

Shift strategy matches the output of our tuned ECU upgrades. In doing so, each gear will shift at the ideal point for the fastest acceleration.

icon

Increased clutch pressure

Maximum targeted clutch pressure is raised to 17.5 bar / 255 PSI giving the transmission the ability to continue raising clutch pressure, as needed, to help prevent slip in higher torque situations.

icon

Increased clutch torque limits

Clutch limits raised, allowing the transmission to function properly at higher torque levels. In doing so, the TCU does not artificially reduce torque.

icon

Manual downshift lockout limit increased

In manual mode, the transmission will allow you to downshift so long as the next is below redline. This includes removal of the first gear lockout.

icon

Lightning fast paddle response

Pulling the manual paddles results in a quicker shift with artificial delays and lag times removed and reduced.

icon

Lightning fast shift times

Shift times are reduced to be as fast as physically and mechanically possible by the transmission. During cruise and light throttle, shift times are transitioned to a slower comfort mode.

icon

Reduced pull-away delay

We’ve reduced the delay experienced when pulling away from a stop for a more natural driving experience.

icon

Customizable auto up-shift behavior

When flashing the transmission, you can choose to have manual mode auto up-shift at redline or stay in gear and bounce off the limiter until you manually shift.

icon

Customizable 3-step launch control

When flashing the transmission, you can choose your maximum launch RPM, which includes 3 launch RPMs that are selectable depending on throttle position.

icon

Lightning fast launch control

We’ve greatly reduced the delay experienced after you release the brake pedal for a quicker reaction time when using launch control.

icon

Launch control enabled with ESP on

Launch control can be used with ESP on. In some situation with the right setup this may improve your launch, although ESP will get in the way with too much tire slip.

icon

Launch counter

There’s no software limit to the number of launches possible on the transmission.

icon

Gear display active in drive and sport

Drive, sport and manual mode all display the current gear in the MFD, digital dash or virtual cockpit.
