𝗧𝗩𝗦 𝗗𝗦𝗚 𝗦𝗢𝗙𝗧𝗪𝗔𝗥𝗘 — 𝗢𝗘𝗠+ 𝗗𝗥𝗜𝗩𝗔𝗕𝗜𝗟𝗜𝗧𝗬. ⚙️

Not every DSG calibration is built for maximum performance. For many applications, the objective is refinement.

TVS Drivability calibrations focus on improving gearbox behavior during everyday driving while enhancing comfort, consistency and overall drivability.

⚙️ Smoother upshifts and downshifts
⚙️ Improved low-speed operation
⚙️ Optimized take-off behavior
⚙️ Refined D and S mode shift strategies
⚙️ Improved overall driving experience

The result: the gearbox behaving the way it should have from the factory.

𝗧𝗩𝗦 𝗗𝗤𝟯𝟴𝟭 𝗗𝗦𝗚 𝗦𝗢𝗙𝗧𝗪𝗔𝗥𝗘 ⚙️🔓

TVS DSG software for the DQ381 GEN2 platform is developed as an application-based calibration system, allowing the transmission behavior to be adapted depending on drivetrain configuration, torque level and usage.

Instead of a fixed “one size fits all” file, multiple calibration strategies are available depending on required operation.

𝗖𝗔𝗟𝗜𝗕𝗥𝗔𝗧𝗜𝗢𝗡 𝗙𝗢𝗖𝗨𝗦 𝗔𝗥𝗘𝗔𝗦

⚙️ Shift strategy optimization (D / S / M modes)
⚙️ Clutch pressure and torque capacity adaptation
⚙️ Launch control behavior and response tuning
⚙️ Thermal and durability-oriented calibration adjustments
⚙️ Engine–gearbox torque coordination refinement

𝗦𝗬𝗦𝗧𝗘𝗠 𝗢𝗣𝗧𝗜𝗢𝗡𝗦 (𝗗𝗘𝗣𝗘𝗡𝗗𝗜𝗡𝗚 𝗢𝗡 𝗔𝗣𝗣𝗟𝗜𝗖𝗔𝗧𝗜𝗢𝗡)

⚙️ Improved D-mode drivability (OEM+ refinement)
⚙️ Faster and more direct S-mode shift logic
⚙️ Manual mode response optimization (paddle & downshift logic)
⚙️ Adjusted take-off behavior and low-speed calibration
⚙️ Launch control activation and enhancement
⚙️ Multi-step launch control (application dependent)

𝗣𝗘𝗥𝗙𝗢𝗥𝗠𝗔𝗡𝗖𝗘 𝗖𝗔𝗟𝗜𝗕𝗥𝗔𝗧𝗜𝗢𝗡𝗦

⚙️ Increased usable torque capacity within gearbox limits
⚙️ Modified clutch pressure mapping under load
⚙️ Reduced torque intervention during gear changes
⚙️ Optimized shift timing for acceleration phases
⚙️ Enhanced repeatability under repeated load conditions

𝗗𝗘𝗣𝗟𝗢𝗬𝗠𝗘𝗡𝗧

TVS DSG software is applied through the TVS dealer network using controlled calibration and flashing procedures, ensuring consistent software behavior across supported applications.

𝗕𝗲𝗵𝗶𝗻𝗱 𝘁𝗵𝗲 𝗗𝗤𝟯𝟴𝟭 𝗚𝗘𝗡𝟮 𝗚𝟬𝟰 𝘂𝗻𝗹𝗼𝗰𝗸 🔓
What looks like a locked system on the outside took over a year of deep engineering work on the inside.

At times, the project reached a point where even internally it was considered non-viable — until a critical exploit changed everything.

To reach that point, deep hardware-level reverse engineering was required:
⚙️ MCU decapping to reconstruct debug architecture
⚙️ Full low-level debug environment setup and enablement
⚙️ Months of firmware reverse engineering and analysis

Step by step, a system that appeared fully secured started to reveal its structure.

What followed was not an adaptation of existing tools — but a fully in-house engineered solution. The result:
🔓 A controlled, repeatable unlocking system for the DQ381 GEN2 G04
💻 Fully integrated into the TVS calibration ecosystem
🚗 Available through the global TVS dealer network
