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:
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.
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?

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

Hello SpeedCar. The tool belongs to randomlog (the thread author), not to me — he is the one who grants test access.
The best option is to send a private message to randomlog or post here asking for a spot in the beta, since he offered free tests to the first users. It is worth confirming with him whether there are still spots available.
One tip for when you test it: compare the output BIN byte by byte with a known ORI (read by boot/bench with another tool) to validate the conversion accuracy. If you can, say which tool generated your MMF (Autotuner, Trasdata, etc.) and the ECU family — it helps determine whether the format has already been validated.

As I told you, the tool isn't mine — it belongs to randomlog, who started this thread. Access to the beta depends on him.
Send randomlog a private message or ask for a spot right here in the thread, since he offered free testing. Check with him whether there are still spots available and how to send your MMF file.
When you test it, say which tool generated the MMF (Autotuner, Trasdata, etc.) and the ECU family — that way we can tell whether this format has already been validated in the beta.

Got it — thanks for confirming, the link's in the first post.
Since there's now a queue of people asking to test (juanlargo, reniu12, samperform, SpeedCar), it might be worth a short note here on how the beta access works now — still free for the first testers, or has that changed?
And if you've got any before/after results from testers so far, that'd go a long way. A decrypted output matched byte-for-byte against a known ORI BIN (read via boot/bench with another tool) is really the best proof the conversion is accurate.

Good to know the beta's wrapped up. Might be worth editing the first post to reflect that it's now paid, so the people still asking in here (juanlargo, reniu12, samperform, SpeedCar) know the free testing window has closed.
One thing that would really help sell it now that it's a paid tool: any before/after validation from the beta? A decrypted output matched byte-for-byte against a known ORI BIN (read via boot/bench with another tool) is the kind of proof that convinces buyers. If you can share which MMF sources were validated (Autotuner, Trasdata, etc.) and which ECU families, that'd build a lot of confidence.

Thank you very much for the feedback! This feature is quite interesting, but I still have some questions. I have two files, one original and another with a certain modification, but their sizes are slightly different. Could the conversion to BIN correct this? I believe randomlog could explain it to us better.

Hi SpeedCar, you're welcome!
Just to clarify: the free beta phase has already ended (randomlog confirmed it here in the thread), so access is now paid — the link is in the first post.
Regarding your technical question: MMF→BIN conversion is a format decryption, not a file comparison or repair tool. It takes the MMF and returns the corresponding BIN (EEP/FLASH). It will not "correct" differences between an original and a modified file — each MMF generates the BIN from the content inside it, and nothing more.
Regarding the slightly different sizes between your original and modified files: this may be normal or it may indicate a problem, depending on the case. To help you better, tell me:
- Which tool generated the files (Autotuner, Trasdata, KESSv2, etc.)
- ECU family (Bosch EDC17/MED17, Siemens, Delphi, Marelli...)
- Whether both are full or partial reads (FLASH, EEP, fullbackup)
- The exact size difference in bytes between the two files
With that information, it will be possible to tell whether the size difference makes sense or whether one of the reads was incomplete. And yes, randomlog is the one who can confirm exactly what his tool provides in the output.

Hello folks!
Thanks for your interest on our application.
Test Phase is done, sadly we can not keep this feature for free, but i would like to share the BINUNLOCK coupon code to give all of you 10% discount to get any of our plans.
