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.
Only use fuel equal to or higher than specified. Never use a lower octane fuel. Always follow our fuel guide, especially with race fuel and Ethanol, where available. Dynosare for reference only. Results will vary. Contributing factors include the vehicle condition, vehicle setup, dyno type, dyno setup, environmental factors, fuel quality, and more. When describing fuels, the North American Region (NAR) uses the Anti-Knock Index (AKI), (RON+MON)/2, or (R+M)/2. The Rest of the World (ROW) uses RON. RON is Research Octane Number and MON is Motor Octane Number.
The APR Difference
Who we are - We’re a global automotive engineering firm nestled in Opelika, Alabama. Our 80,000ft² state-of-the-art facility is home to some of the best engineers in the industry, who have mastered hundreds of engine management systems. We have multiple engine and chassis dynos, and the resources necessary to create our TCU Upgrades in-house, from the ground up! We're not a new company either. We've been around since the 90's and we have a strong financial backing to ensure we'll be here to support you for decades to come!
What we do - We optimize everything to make your transmission more capable. We don’t take shortcuts, and we don’t take risks. We do it the right way.
How we differ - With our proprietary calibration and direct ram access data logging tools and operating system code changes, we’re able to make some of the best TCU upgrades, without needing costly end user adjustments.
