Product Information
APR TCU DL501 Transmission Upgrade Tune For Audi S4/S5/S6/S7
Brand Description:
USP Motorsports is proud to offer products from the global leader in performance aftermarket products, APR. APR develops and manufactures hardware, software, calibration & data-logging tools for engine and transmission controllers, including intakes, exhaust systems, intercoolers, turbocharger systems, suspension, brake systems, wheels, and more.
Product Description:
Optimize the driving experience with our performance tuning software for your vehicle's Transmission Control Unit (TCU).
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 torque limits
- Manual downshift lockout limit increased
- Lightning-fast paddle response
- Lightning-fast shift times and AMAX mode
- Reduced pull-away delay
- Customizable auto up-shift behavior
- Customizable auto down-shift behavior
- Customizable 3-step launch control
- Lightning-fast launch control
- Launch counter
- Temperature management optimized
- Gear display active in drive and sport
- Direct Port Programming - Clean and easy install through the OBD II port without removing the ECU
Applications:
- Audi S4 3.0T (2010-2016)
- Audi S5 3.0T (2010-2017)
- Audi S6 4.0T (2013-2018)

At Home APR Flashing - How does it work?
USP Motorsports has made at home APR Software as easy as 1, 2, 3...
1. Purchase the software applicable to your vehicle (this page)
2. Purchase the required hardware (APR Cheetah Cable) - Links below
3. Complete the form that will be emailed to you after checkout. This will arrange all the necessary steps to complete the flashing process.
Required Hardware: APR Software Flashing Cheetah Cable (Get Up to 80% back of what you paid for this*)
Recommended Hardware Kit: APR At Home ECU/TCU Flashing Kit (This kit includes the cheetah cable above)
After checkout, you will receive an email from USP Motorsports with instructions on how your ECU/TCU can be flashed.
NOTE: This software must be purchased along with a required APR Software Flashing Cheetah Cable. (Note: We highly recommend getting the complete APR At Home ECU/TCU Flashing Kit to avoid any potential issues during the flashing process)
TCU Features:
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 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 auto down-shift behavior
When flashing the transmission, you can choose to have manual mode auto down-shift feature enabled or completely disabled.
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.
Temperature management optimized
If an overheat condition occurs, the factory tune shuts down the transmission. We dramatically limit torque so the vehicle is still usable enough to get out of harms way.
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.
Acceleration Improvements
Our TCU Upgrade improves acceleration. This is accomplished by adjusting Launch control, optimizing shift points, enabling AMAX mode, reducing shift duration, reducing shift intervention, and more. The graphs show longitudinal acceleration G-Forces and vehicle speed on an APR Stage 2 Audi S4. With our TCU Upgrade, acceleration is stronger after the launch, and carries with the modified redline. During the shift, intervention is far less, keeping G’s higher. The 0-120 MPH spring was reduced .75 seconds and .97 seconds on a vehicles experiencing a short shift. Furthermore, some models, such as the 3.0T, experience maximum power at an RPM unachievable on the stock transmission software. With our TCU Upgrade, the transmission will shift higher, and create reach higher HP levels.
