VAG Group ECU Platforms
VAG EDC15 / EDC16 Calibration
Bosch EDC15 and EDC16 ECUs are found across many older VAG diesel applications. EDC16 introduced a more advanced torque-based control strategy, with Volkswagen describing it as a torque-orientated diesel engine management system. Popular VAG EDC16 variants include EDC16U1, EDC16U31, EDC16U34 and EDC16CP34. These platforms remain well suited to tailored calibration focused on drivability, response and usable torque.
Older VAG diesel platforms still have a lot to offer when calibrated properly. Whether your vehicle uses Bosch EDC15 or EDC16, the goal is the same: better drivability, stronger usable torque and a result that suits the vehicle in the real world.
VAG EDC17 Calibration
Bosch EDC17 is a common diesel ECU family used across many modern VAG Group vehicles and is the successor to EDC16. These platforms are well suited to tailored calibration focused on drivability, response and usable torque, with the exact solution depending on the specific ECU, engine and vehicle application.
Many modern VAG diesel vehicles use Bosch EDC17 ECUs, offering a strong platform for tailored calibration. The goal is simple: better drivability, stronger usable torque and a smoother, more responsive vehicle in the real world.
VAG MD1 / MG1 Calibration
Many newer Audi, Volkswagen, SEAT, Skoda and Cupra models use Bosch MD1 and MG1 ECUs. These newer diesel and petrol platforms often require a more advanced approach, with the correct method depending on the ECU type, hardware version and vehicle application. Common VAG examples include MD1CP004, MD1CP014, MD1CS004, MD1CS014, MG1CS001, MG1CS002, MG1CS008, MG1CS011, MG1CS111, MG1CP007 and MG1CS047
Modern VAG petrol and diesel vehicles often use Bosch MG1 and MD1 ECUs, with each platform requiring the right method for the exact application. The goal is simple: a safe, informed calibration approach that suits the vehicle properly
Please note: Many post-June 2020 Bosch MD1 / MG1 applications require a mail-in unlock before calibration can be carried out. As support can vary by ECU and vehicle, the correct method should always be confirmed first. Coverage for these platforms is evolving regularly, so the latest support should always be checked before booking. We can handle this all for you
VAG TCU Custom Calibration
Modern VAG Group vehicles can benefit just as much from gearbox calibration as they can from engine calibration. On many Volkswagen, Audi, SEAT and Skoda models, the factory gearbox software is designed to suit a broad range of drivers and operating conditions, but that does not always mean it is optimised for response, shift strategy or the way an enthusiast or fast-road customer wants the vehicle to behave.
Our VAG Group gearbox tuning solutions are designed to improve the way the transmission performs in the real world. Depending on the platform and gearbox type, this can include sharper shift response, improved gear selection logic, better use of the powerband, more decisive kickdown behaviour, improved manual mode behaviour and revised torque interaction between the engine and transmission. The aim is not just faster shifting for the sake of it, but a more refined and better-matched driving experience.
For many VAG vehicles, gearbox tuning can transform the overall feel of the car. A well-calibrated transmission helps the vehicle stay in the right gear for longer, respond more naturally to throttle input and make better use of the available torque. On tuned vehicles, gearbox calibration is often an important part of the package, especially where the standard transmission software includes torque limiters or conservative shift behaviour.
We offer tailored solutions across a wide range of VAG DSG and S tronic platforms, with the correct approach depending on the exact gearbox, vehicle and intended use.
Popular VAG Group gearboxes we work with
DQ250 – 6-speed DSG
One of the best-known VAG dual-clutch transmissions, the DQ250 was the first DSG gearbox introduced by Volkswagen AG and remains a very common platform across older and mid-generation VAG performance and diesel models.
DQ381 – 7-speed DSG
A newer wet-clutch transmission introduced as a more efficient successor in many applications, the DQ381 is used in modern high-torque front-wheel-drive and four-wheel-drive vehicles, with TVS Engineering noting examples such as the Arteon, Golf 7.5 R and facelift Audi S3.
DQ500 – 7-speed DSG
The DQ500 is a stronger 7-speed transverse DSG platform used in higher-torque applications. TVS notes its use in models such as the Volkswagen Transporter, Tiguan, Audi RS3 and TT RS, which is why it is one of the most popular gearboxes in the VAG performance world.
DL501 – 7-speed S tronic
The DL501, also known as the 0B5, is Audi’s longitudinal 7-speed oil-cooled dual-clutch transmission. It is commonly found in longitudinal Audi applications and is one of the key gearbox platforms where good calibration can make a big difference to drivability and shift quality.
DQ200 – 7-speed DSG
The DQ200 is another widely known VAG gearbox, generally found on lower-torque applications. While it is common across the group, suitability and available tuning options depend on the exact vehicle and transmission condition, so this is always something we assess on an application-by-application basis. The source describing DQ250 notes DQ200 as one of the dry-clutch DSG variants used on weaker power units.

Why TCU Calibration Matters
The transmission is responsible for how performance is delivered. A properly calibrated TCU can improve shift speed, response, torque handling and overall drivability.
Why Combine ECU & TCU Calibration?
When calibrated together, the engine and gearbox can work more effectively as one system. This often results in improved shift behaviour, better response and a more refined driving experience.
