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 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 DQ381 G2 EQUIPPED GTI’S
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 GTI!

DYNAMIC+ ECU FEATURES:
THERMAL MANAGEMENT SAFETY STRATEGIES:
With increased power, comes increased heat. With increased heat, comes the need for additional management. For charge air temperature, 034Motorsport has implemented key safety features to keep your engine running optimally and safely in virtually any condition - just like the OEM calibration. Substantial effort was spent on balancing the trade off of charge temp for power, and improving the compressor efficiency so that it doesn't generate too much charge temp.
Charge Air Temp: When the charge temp exceeds 80*C there is a reduction in power output. When the charge temp exceeds 85*C there is a more significant reduction in power output. This charge temp limitation is there to prevent knock events, which can severely damage a motor. With these safety measures in place, you can confidently drive your car, from the top of Pikes Peak to Death Valley, knowing the factory ECU has optimal performance and safety covered..
Coolant Temp/Fan Strategy: From the factory, Volkswagen likes to run hotter water temps to reduce fluid friction losses from cooler, more viscous oil. While better for efficiency, this strategy becomes a safety issue when loads and heat are increased. 034Motorsport calibrators have rescaled the coolant temperature targets and fan control strategies to target lower coolant temperatures when in higher heat conditions, allowing the car to run within a safe heat range rescaled for the added heat that comes from tuning the engine. Once again, this means that 034Motorsport calibrators have kept your confidence in safety fully intact from the OEM configuration.
FUEL SYSTEM OPTIMIZATION:
While E85 provides substantial increases in power, it requires about 30% more fuel than standard pump gasoline per ignition cycle. Utilizing a variety of fuel stratified injection strategies, 034Motorsport calibrators have further optimized the factory fueling system to be able to adequately support full E85 on factory hardware for Stage 1 & Stage 2.
START/STOP BUTTON MEMORY:
Dynamic+ Tuning for the EA888.4 2.0T retains the Start/Stop engine functionality, but allows users to set the memory for the system based on preference. If you do not want the Start/Stop system to run, turn it off via the in-cabin button and the car will store that selection even after key cycling the car. If you would like it to stay on, select it to be on via the in-cabin button. This is done in a completely OEM fashion, helping enhance the overall experience of driving your car!
ENHANCED CRACKLES IN SPORT MODE:
034Motorsport engineers have enhanced the crackles for maximum auditory pleasure on both Stage 1 & Stage 2! Crackles can be toggled on or off via Drive Select. They will be on in Sport and off in Comfort/Eco , giving you the ability to crackle when you want, and cruise quietly when you don't. In Individual, crackles can be toggled on or off via Engine Sound.
FREE REVVING IN NEUTRAL AND PARK
The rev-limiter is now removed while in Neutral and Park. Impress friends and annoy those around you with limitless ease!
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 AND STAGE 3 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.
