Description
This WinOLS Basic Mappack + DTC for Bosch MED17.5.21 ECU provides a professionally structured calibration project developed for advanced ECU analysis, performance tuning, and diagnostic applications.
The project includes structured and verified ECU maps (no potential or unverified data), organized into clearly defined functional areas for efficient workflows and precise calibration handling.
DTC mask and path structures included, enabling targeted fault code removal, diagnostic adjustments, and system-related modifications.
This ECU platform is widely used in VAG turbo petrol applications equipped with 1.2T engines.
⚠️ This product does not contain a tuned file.
The original ECU file is embedded in the WinOLS project, allowing immediate access after import.
