November 2025 – ECUFILES Release
New Stage 1 and Stage 2 tuning files for the Audi A1 1.2 TFSI with Siemens SIMOS10.2x ECU.
Unlike the weak and incomplete files you often see elsewhere, our files use proper OEM-based maps. This means more power, smoother delivery and no unnecessary component-protection blanking. All safety limits stay active.
The result is a lively, fun A1 that feels exactly how it should – just stronger.
Why these files are better:
- Built on original OEM maps
- Noticeable power gains
- Smooth and natural delivery
- No blanking of protections
- All safety limits active
If you’ve tried other files and been disappointed, these will feel right.
Already available in your ECUFILES account.
