Leon Cupra 2.0 TFSI CDLA — MED9.1 502834 Bosch — ECU Files
This Stage 1 tune is engineered to unleash the full enthusiast potential of the Seat Leon Cupra 2.0 TFSI, powered by the renowned CDLA engine and managed by the Bosch MED9.1 ECU (software 502834). This calibration is designed to transform the driving experience, making the already capable hot-hatch feel significantly faster and more responsive.

Our remap focuses on delivering a more aggressive power curve, with a substantial increase in torque that you can feel throughout the rev range. We have sharpened the throttle response for an instant connection to the engine's power and optimized the boost and fueling maps for maximum performance on a mechanically stock vehicle. This is the definitive software upgrade for any Cupra owner looking for a more thrilling and rewarding drive.
