034Motorsport Dynamic+ TCU Software Upgrade for DQ381 G2 DSG Transmission – VW / MK8 / GTI

401 Bootloader Flashability

While these newest Full Torque on Locked TCU files allow those with unflashable 401 bootloader transmissions to experience the fullest power potential of the EA888.4 Engine, it does not allow us to apply the whole host of transmission tuning improvements found in our DQ381 G2 TCU tuning. 034Motorsport Engineers are still working diligently at unlocking the 401 bootloader to allow for future TCU tuning. This process is incredibly complex and thus has no formal timeline for when it will be complete, but rest assured our team are still working to provide the full suite of tuning to all Locked TCUs. For more details on what this process looks like, watch this video here:

Unlock the true potential of the EA888.4 Engine with 034Motorsports new Full Torque ECU Files for Volkswagen MK8 GTI’s with 401-Bootloader Locked Transmissions! Designed for owners with locked TCUs, these files allow your engine to deliver the full torque output of your 034Motorsport ECU Tune while remaining fully compatible with the factory TCU tune. These files are available for all stages and fuel octanes, including Stage 3R & Powermax files for GTI.

Through specialized calibration changes, our Full Torque on Locked TCU files enable the ECU to communicate higher torque values to the locked TCU, which ensures the Stock TCU provides increased clutch clamping pressures, allowing for seamless integration of the enhanced torque output. The result? Unmatched performance with safe and reliable power delivery. This means you can safely enjoy Full Torque on your Locked TCU vehicle without concern for long-term reliability. These files have been rigorously tested in-house in high-abuse racing scenarios, on the road, and with a fleet of early adopters around the world to ensure safety above all else is retained.

To flash this new file, simply select the option designated in your flashing portal, “Locked TCU,” choose your octane, and flash!

PRODUCT DESCRIPTION:

Flashed directly through your vehicles OBD-II port, 034Motorsports proprietary Stage 2 calibrations for the DQ381 G2 TCU safely and effectively optimize its operation for Stage 1 and Stage 2 Performance ECU Software. The result is a noticeable improvement in acceleration, without sacrificing comfort or reliability.

034MOTORSPORT MK8 GTI DQ381 G2 STAGE DESCRIPTIONS:

Stage 1 (Included with Purchase of 034Motorsport MK8 GTI Stage 1 & Stage 2 ECU Tuning):

034Motorsport Stage 1 Transmission Performance Tuning Software for the DQ381 G2 is included in the Dynamic+ Tuning Bundle with our Stage 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 DQ381 G2 is designed to further improve the drivability and performance of your Dynamic+ Tuned MK8 GTI. Dynamic+ Stage 2 TCU Software can be used with our Stage 1 OR upcoming Stage 2 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 improves the launch control strategy to ensure you have the most optimal launch possible.

DYNAMIC+ TCU FEATURES:

STAGE 1 TCU TUNE:

Torque Safety Strategy Enhancements:

• 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.

Clutch Pressure Increases:

• In order to safely apply the increased horsepower and torque, DSG Clutch Pressures are increased in all drive modes. Expect to feel firmer and more solid shifts!

STAGE 2 TCU TUNE:

Torque Safety Strategy Enhancements:

• 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.

Clutch Pressure Increases:

• In order to safely apply the increased horsepower and torque, DSG Clutch Pressures are increased in all drive modes. Expect to feel firmer and more solid shifts!

Optimized Shift Points:

• In order to take advantage of the increased powerband from the turbocharger, Dynamic+ Tuning optimizes the shift points in Drive & Sport Mode to maximize acceleration while retaining smooth drivability.

Improved Shift Speeds:

• To further enhance the acceleration of your GTI, the DQ381 G2 shift times are dramatically decreased in all driving modes, which ultimately results in quicker acceleration.

Launch Control Optimizations:

• From the factory, the DQ381 G2 launch control strategies used are very neutered and designed for a vehicle on a non-optimal surface with low-grip tires. 034Motorsport Engineers have optimized the launch by raising the factory torque limit to take advantage of a better surface and a grippier tire. This ensures that your GTI will 60ft much more effectively and efficiently!
• Additionally, significant work was put into refining how AMAX shifts are applied during Launch Control, ensuring that each shift maximizes potential acceleration without inducing wheelspin.
