034Motorsport Dynamic+ Tuning ECU & DQ381 G2 TCU Tuning Bundle - VW / 2.0T / EA888.4 / 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.

Unlock the true potential of the EA888.4 Engine with 034Motorsport’s 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!

Customize Your Dynamic+ Tune Like Never Before

Built for Real-World Performance

The 034Motorsport Dynamic+ Tuning Software for MK8 Volkswagen GTI equipped with the EA888 Gen 4 2.0T inline-four engine is designed to transform the driving experience of your vehicle! Flashed directly through your vehicle’s OBD-II port, 034Motorsport’s proprietary calibrations for the ECU safely and effectively increase the power output of the turbocharged inline-four in a refined manner. The result is a significant improvement in acceleration and throttle response, without any sacrifice in drivability or reliability.

034Motorsport MK8 Volkswagen GTI EA888 Gen 4 2.0T Dynamic+ Performance Software was developed entirely in-house on 034Motorsport's Development MK8 GTI. The calibrations were then refined on multiple enthusiast-owned beta tester cars around the world.

Included at no extra cost is the Stage 1 Dynamic+ Performance TCU Software for MK8 Volkswagen GTI equipped with the DQ381 G2 7-Speed DSG transmission. At an extra cost, upgrade to the Stage 2 TCU Tuning to further enhance the shifting and acceleration of your DSG Equipped 2.0T! Flashed directly through your vehicle’s OBD-II port, 034Motorsport’s proprietary calibrations for the DQ381 G2 TCU safely and effectively raise the torque limits of the DSG, allowing your car to make use of Stage 1, Stage 2, Stage 3R, or Stage 3 PMAX Performance Software.

034Motorsport Dynamic+ offers manual transmission users Low Torque files to maximize performance and the clutch life of stock clutch equipped manual MK8 GTI’s. These files are included at no additional cost for all octanes!

034Motorsport Engineers develop special in-house tools that allow us to access the firmware and maps inside the factory ECU—this level of engineering is required to prevent workarounds and band-aids that many aftermarket companies resort to. 034Motorsport engineers and optimizes the ECU calibrations just like Volkswagen engineers would, accessing the source of how the ECU controls the engine and making changes at the base level.

NOTE: The E85 calibration is not a flex-fuel style tune. The tune will work with E85 directly from the pump, both summer and winter blends (ethanol content can vary from E60-E85). This tune requires only E85 be pumped into the fuel tank. Gasoline blends and race fuel mixtures should not be used, and engine damage could occur if the incorrect fuel or octane is used. We strongly recommend an ethanol content gauge be used so that you can monitor the actual ethanol content at the pump you are using. When switching fuels, it takes about 20-30 minutes of normal driving for the new tank of fuel to fully circulate through the system when filled at E. Please minimize load (don’t floor it!) until you have driven the car for at least 30 minutes.

***All octane ratings are in US standard AKI (RON+MON). Some ROW countries such as the UK use a RON octane rating that differs from US Octane ratings. Please email tuning@034motorsport.com to ensure you are running the correct octane file for your area. Running the incorrect octane file for your fuel can result in irreversible damage.
