Firmware management without chaos

Professional tool for instant search, matching, filtering and mass downloading of CFF and SMR-F files for Mercedes-Benz control units.

CRD_MR Viewer Demo

Created for engineers and chip tuners

Killer Feature

Factory tuning and Ecology Downgrade

Forget about searching for compatible versions blindly. Filter databases for instant selection of factory software with increased power or for safely lowering the ecological class (switching to Euro 5, Euro 4 or Euro 3) without using third-party editors.

Full package assembly

Select the perfect file combinations for safe flashing. The program allows you to easily find matching sectors: Boot, main Soft and factory Calibrations.

Speed and Locality

Search through encrypted local databases takes milliseconds. No delays on server requests — filtering results by HW, SW or chassis are displayed instantly.

Built-in Downloader

Mass download missing firmwares directly from Mercedes servers. The program checks file availability and downloads only the necessary software in one click.

Smart Sorting

Bring order to your archives. The utility will analyze thousands of downloaded files and neatly arrange them into folders depending on the ECU number, chassis, or class.

Full control

Edit databases, import new links (JSON) and use row color markup to label custom or test software versions.

Security and Backups

Your custom database is under reliable protection. The program automatically creates backups (Backup/ORI system) and encrypts database files with the AES algorithm.

Latest Updates

v1.1.7 June 2026

Global Database Optimization & Smart Freeze

Databases rebuilt from scratch, CRR2 units moved to OM654. Added a new OTA engine for smart database updates, an extended File Info window, and the new Smart Freeze feature.
