APR's TCU Upgrade dramatically improves upon the 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! 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.

Features:

  • Optimized part throttle drive and sport maps
  • Optimized wide open throttle drive and sport maps
  • Increased clutch pressure
  • Increased clutch torque limits
  • Manual downshift lockout limit increased
  • Lightning fast paddle response
  • Lightning fast shift times and AMAX mode
  • Reduced pull-away delay

User adjustable features are available at the time of flashing. Driving map profiles are also available for different size turbos. There is no charge from APR to change these settings. Some features may be limited if using an APR Plus ECU Upgrade. Compatibility notes: Some 2.0T Ea888.4 vehicles with a build date of 01/2022+ are not currently compatible due to a locked TCU. Please Note: Each vehicle's year, make, and model may have multiple factory engine or transmission controller software part numbers, known as box codes, each with unique revisions. Manufacturers periodically release software updates that alter this information, which can only be determined by scanning the controller and is not publicly provided. Due to the variety of codes, some stages, octane levels, features, or options may not be available for specific codes. Therefore, our website provides a general guide based on general info such as Year, Make, and Model. Our system allows you to request unavailable software, and we offer a 30-day money-back guarantee if you're not satisfied.

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.

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.

Increased clutch pressure

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

Increased clutch torque limits

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

Manual downshift lockout limit increased

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

Lightning fast paddle response

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

Lightning fast shift times and AMAX mode

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. During a launch, AMAX mode is enabled for high torque shifts.

Reduced pull-away delay

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

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.

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.

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.

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.

Launch counter

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

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.
