034Motorsport B9/B9.5 Audi RS4/RS5 AL552 ZF8 Stage Descriptions:

Stage 1 (Included with Purchase of 034Motorsport EA839 ECU Tuning):

034Motorsport Stage 1 Transmission Performance Tuning Software for the AL552 is included in the Dynamic+ Tuning Bundle with our Stage 1/1+ ECU software.

The Dynamic+ ECU Tuning accurately reports torque values to the TCU to ensure that all safety systems are intact in both control units, and the added torque from tuning is properly adjusted for when driving/shifting, including all safety systems designed to protect the engine and transmission. This results in better shift quality as the transmission is not having to reduce engine torque or having to adapt to misreported inputs.

Stage 2:

The 034Motorsport Stage 2 Transmission Performance Tuning Software for the AL552 is designed to further improve 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.

Stage 3:

The 034Motorsport Stage 3 Transmission Performance Tuning Software for the AL552 is designed to further improve the drivability and acceleration performance of your Stage 3 Dynamic+ Tuned Audi B9/B9.5 RS4 or RS5. Dynamic+ Stage 3 TCU Software is designed to be used with Dynamic+ Stage 3 ECU Software. 034Motorsport Stage 3 TCU Tuning further optimizes shift points under partial and full throttle to keep the TTE720 Turbochargers in their peak power band, and raises the redline to 7,200 for maximum performance with the larger turbocharger!

PERFORMANCE TCU STAGE 2 SOFTWARE FEATURES:

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 in a safe and reliable manner. Within both the ECU and TCU, there are factory safety tables that limit overall torque output based upon what the factory first tuned the car for. The ECU reports the output of torque 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 upon its safety tables.
  
  
• 034Motorsport takes a holistic approach with its Dynamic+ Tuning, and aims to retain as many OEM safety protocols as possible. While it is possible to tune around the factory TCU torque limiters from the ECU side, 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

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

Improved Shift Speeds

• To further enhance the acceleration of your Audi, the ZF8 shift times are dramatically decreased in all driving modes, which ultimately results 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 less lazy shifts, more firm shifts, which ultimately results in quicker acceleration.
