034 Motorsport Australia - Audi S3 8Y - Stage 2 DQ381 DSG/TCU Tune
034 Motorsport is proud to offer Stage 2 TCU software for your Audi S3 8Y equipped with the DQ381 G2 7-Speed DSG transmission! Flashed directly through your vehicle’s OBD2 port, 034Motorsport’s proprietary calibrations for the DQ381 G2 TCU safely and effectively optimise its operation for Stage 1 and Stage 2 Performance ECU Software. The result is a noticeable improvement in acceleration, without any sacrifice in comfort or reliability.
In addition, End User Flashing allows Dynamic+ Performance Software customers to receive and install software updates and revisions, flash back to stock, or upgrade to the next stage of performance software for their vehicle. You will need to purchase a Dynamic+ flash cable to tune your TCU - 034-103-3306
* please note some later year gearbox software is in development. We will not know if your gearbox is compatible for flashing until your stock TCU software version is identified when you first flash your ECU. If your gearbox is not compatible 034 Motorsport will supply an alternative ECU file to run.
STAGE 2 DQ381 G2 DSG 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!
Kickdown Switch Disabled in Manual Mode:
When in Manual mode, you no longer need to worry about accidentally pushing through the kickdown switch on the throttle pedal!
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 Golf R and 8Y Audi S3, 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 Golf R and 8Y Audi S3 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.

This will send an email to you that will allow you to set your own password, which you'll need to use to log into the flashing client software. Once you are logged into the flashing client, please click on the controller that you wish to program (either ECU - engine, or TCU - transmission) and proceed through the steps listed in the "Getting Started" guide to flash that controller. The files labeled "Stock" are completely OEM software calibrations, as you would have received from the factory, so please only flash these if you wish to go back to stock tuning.
I received an error message stating that "No products are available for this controller", what do I do?
If you receive the error message "No products are available for this controller", please email tuning@034motorsport.com directly, and someone from their tuning support team will advise you on the steps that they will take to get you access to the files that were purchased.
A: This is NOT a difficult process. If you have the ability to open and email and send an email, this is the same level of computer literacy needed.

A: The total time to tune the car is around 30 mins. Flashing between files, upgrading and so on once you have done the first installation is a couple of minutes.
I need some technical support. Who do I contact?
Please email tuning@034motorsport.com and a dedicated tuning support representative will help address any concerns or questions you may have.
Q: My car already has a tune on it, how do I remove it?
A: You may need to flash your car back to stock. You can do this by flashing the car to stock using the 034Motorsport flashing portal.
Q: Do I have to flash my ECU and TCU?
A: Yes, these are separate control units and need to be individually flashed.
Q: What is 91 AKI and 93 AKI? RON to AKI?
A: 91AKI is 95 RON and 93 AKI is 98 RON. When flashing select the file appropriate to the fuel octane you are using.
