The 034Motorsport Dynamic+ Tuning Software for MK8 Volkswagen Golf R and 8Y Audi S3 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 driveability or reliability. 034Motorsport MK8 Volkswagen Golf R and 8Y Audi S3 EA888 Gen 4 2.0T Dynamic+ Performance Software was developed entirely in-house on 034Motorsport's Development 8Y Audi S3. 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 Golf R and 8Y Audi S3 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 Performance Software. 034Motorsport Dynamic+ offers manual transmission users Low Torque files to maximize performance and the clutch life of stock clutch equipped manual MK8 R’s. These files are included at no additional cost for all octanes! 034Motorsport Engineers develop special inhouse tools that allow us to access the firmware and maps inside the factory ECU, this level of engineering is required to prevent work-arounds and bandaids that many aftermarket companies resort to. 034Motorsport engineers and optimizes the ECU calibrations just like Volkswagen engineers would, but accessing the source of how the ECU controls the engine and making changes at the base level. This is the ONLY way 034Motorsport can ensure our calibrations meet our high standards for ultimate power with smooth drivability, perfect function, reliability and added functions and features even beyond what the factory programming can provide. 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. Ethanol content analyzers installed close to the fuel rail will also help you see when the ethanol has fully run through the system. UNLOCKING EXTRA TORQUE IN THE DQ381 G2 EQUIPPED GOLF R AND 8Y S3 As with any automatic transmission vehicle, the ECU and TCU computers work synchronously to properly apply torque to the vehicles 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. For vehicles that have a TCU that cannot be tuned, the ECU will safely limit the overall torque that is able to be produced. It is safe to drive your car in this condition with only the ECU tuned. 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. We are happy to provide our Stage 1 Dynamic+ TCU tuning at no additional cost ($150 value) to the customer in order to ensure that you are maximizing the performance and reliability of your MK8 Golf R and 8Y Audi S3!
