This is a Stage 1 calibration file for the Temic DQ200 Transmission Control Unit (TCU) in the Seat Leon 1.8 TSI with a DSG7 gearbox. This is not an engine tune, but a crucial upgrade for the gearbox itself, designed to improve shifting logic, increase performance, and enhance durability.
A TCU tune is essential for vehicles with a tuned engine, as it raises the gearbox's internal torque limiters, allowing the engine to safely deliver its new power. This calibration also significantly speeds up shift times, optimizes the shift points in D and S modes for a sportier feel, and increases the clutch clamping pressure to prevent slip under higher torque loads. This results in a much faster, more responsive, and more engaging driving experience.
