034Motorsport is proud to offer Stage 2 TCU Software for B9/B9.5 Audi RS4 or RS5 models equipped with the AL552 8-Speed ZF8 transmission! Flashed directly through your vehicle’s OBD-II port, 034Motorsport’s proprietary calibrations for the AL552 TCU safely and effectively optimize its operation for Stage 1/1+ Performance ECU Software. The result is a noticeable improvement in acceleration, dropping your 0-60mph time by 0.1 seconds without sacrificing comfort or reliability.

In addition, End User Flashing allows Dynamic+ Performance Software customers to receive and install software updates and revisions, flash back to stock, or upgrade to the next stage of performance software for their vehicle. Some TCU Box Codes may require additional development time or a read of the factory ECU before the software is available.

The 034Motorsport Stage 2 Transmission Performance Tuning Software for the AL552 is designed to improve further the drivability and performance of your Dynamic+ Tuned Audi B9/B9.5 Audi RS4 or RS5. Dynamic+ Stage 2 TCU Software can be used with our Stage 1/1+ ECU software.

034Motorsport Stage 2 TCU Tuning further improves shifting performance and speed for casual and track driving in all driving modes. Dynamic+ Tuning also activates AMAX shifting to ensure the quickest and most efficient shifting strategies while launching your vehicle. These changes result in a significant improvement in acceleration and lower 0-60 and ¼ mile times.

Improved Torque Management

• As with any automatic transmission vehicle, the ECU and TCU computers work synchronously to properly apply torque to the vehicle's drivetrain safely and reliably. Within the ECU and TCU, factory safety tables limit overall torque output based on what the factory first tuned the car for. The ECU reports the torque output from the engine to the TCU, and the TCU decides if this is suitable or too much. If it is too much, the TCU will command the ECU to reduce torque output based on its safety tables.
• 034Motorsport takes a holistic approach with its Dynamic+ Tuning and aims to retain as many OEM safety protocols as possible. While tuning around the factory TCU torque limiters from the ECU side is possible, this is done at the expense of torque safety features that are integral in keeping your transmission running safely. 034Motorsport’s calibrators tune the ECU to work with the TCU to provide accurate torque values and recalibrate the appropriate safety ranges for the TCU. Taking these extra steps to retain OEM safety systems on the ECU and TCU side is just one of the many reasons that Dynamic+ software provides substantial yet reliable performance increases.

Optimized Shift Points

• Dynamic+ Tuning optimizes the shift points in all driving modes to maximize acceleration during wide-open throttle scenarios to take advantage of the increased powerband from the turbochargers.

Improved Shift Speeds

• To further enhance the acceleration of your Audi, the ZF8 shift times are dramatically decreased in all driving modes, resulting in quicker acceleration. Shift times are now up to 70% faster!
• Shift pressures are also increased in Sport Mode to maximize performance. In Sport Mode, you will notice fewer lazy and firm shifts, resulting in quicker acceleration.

AMAX Shifting

• AMAX Shifting is a shifting strategy that stands for “Acceleration Maximum.” These gear shifts are the fastest and quickest possible for optimal acceleration. These are activated in shifting after launching your vehicle from a stop using launch control.
• AMAX is now activated in the 4>5, 5>6, and 6>7 shifts where it was previously disabled from the factory.
• When in AMAX mode, line pressures in the transmission have been optimized to increase shift speeds safely.

Increased Launch Stall RPM

• The launch stall RPM has been raised for a significant increase in force, allowing you to get off the line as fast as possible.

Delay Time Between Launches Reduced

• The delay time between launch control activations has been shortened. This is useful when drag racing to heat up tires using launch control and re-activate quickly before launching down the drag strip!
