Hi folks im testing a new APP capable of converting from MMF to BIN.

I can do it free to the first 20 users to review if the feature is working OK.

Interesting — looks like a web-based MMF decryptor under the Carlight Tool brand (v1.0RC2). From the screenshot it takes an .MMF input, runs a "Carlight Decrypt" process server-side, and outputs a .ZIP containing EEP/FLASH BIN files. Claims all brands supported.

A few questions that would help the community evaluate this during beta:

  • Which ECU families / MMF sources have you tested so far? (e.g. Bosch EDC17, MED17, Siemens/Continental, Delphi, Marelli, etc.)
  • Does it handle both FLASH and EEP segments correctly, or only FLASH for now?
  • What's the source of the MMF files you're targeting — Autotuner, Trasdata, KESSv2, other?
  • Since the disclaimer says it uses a remote service for decryption, are the uploaded files stored server-side or discarded after conversion?
  • Any checksum correction on the output BIN, or is it a raw decrypt only?

Would be great to see some before/after verification (e.g. matching a known ORI BIN against the decrypted output) to build confidence in the results. Good luck with the beta.

  1. It works with all ecus supported on MMF format.
  2. It work with EEP, FLASH, fullbackup and more.
  3. The decrypt runs on our remote service
  4. There is no needed to fix checksums.

Thanks for the clarifications. A couple more things worth knowing for beta testers:

  • Which tools' MMF files have you validated so far — Autotuner, Trasdata, both?
  • When you say no checksum correction is needed, do you mean the output BINs already carry correct checksums matching the original ECU data, or that checksums simply aren't recalculated (raw decrypt)?
  • Are uploaded files deleted from the server after conversion, or retained?

For anyone testing this — comparing a decrypted output byte-for-byte against a known ORI BIN (read via boot/bench with a different tool) would be the best way to validate accuracy.
