What you’ll receive
Input One FRF or SGO firmware file File limit 64 MiB per file Your original stays separate from the result.
Using your download The ZIP keeps each extracted block separate. Check the block addresses and conversion warnings before using the files.
Use files that match your ECU and software version. A converted container is not a tuned calibration.
How to convert your file
Choose the original factory container shown above. The filename extension must match the supported input. Upload the file and sign in to your free account. Processing continues after the upload has been saved. Open My uploads to download the original, converted files and report again. FRF and SGO firmware blocks
FRF and SGO are factory firmware containers used across Volkswagen, Audi, SEAT and Skoda applications. Support depends on the container encoding and ECU profile; the extension alone does not establish compatibility.
A container may hold several software or calibration blocks. The ZIP contains the extracted BIN files, source and address metadata, and any conversion warnings. Keep these together: concatenating the blocks does not necessarily produce a complete flash image.
Working with addresses
For example, a block declared at address 0x800000 does not imply that the BIN contains eight megabytes of preceding data. Use the address recorded in the report when mapping the block into your editor.
After extraction, you can check a supported ECU checksum or extract map definitions for WinOLS using compatible files.
