WinOLS NOREAD remover

Find visible NOREAD markers in an exported ECU binary. Review each replacement and download a separate processed copy.

Inspect your binary

Find visible ASCII NOREAD markers, review the replacements, then download a separate copy. Each marker is replaced with FF or 00 to match its surrounding padding.

What you’ll receive

Processed BIN and change report

Input: Exported raw ECU binary
File limit: 64 MiB per file

Your original stays separate from the result.

What this tool handles

Visible NOREAD text in raw binaries, including repeated markers. It requires at least four matching padding bytes on each available side. Mixed or uncertain padding is flagged for review.

Invisible WinOLS signatures, passwords and encrypted files require a different approach. Finding no visible marker does not prove that a file is unrestricted.

Need map definitions instead? Extract supported A2L, KP, OLS or XDF files to WinOLS CSV.

Check the checksum before programming. This tool changes marker bytes and does not correct ECU checksums. Verify or correct the output with a tool that supports your ECU.
