I have about 10 bins and I can do all that, it's just a question of what is the most useful format for You

All I really need is ok or fail.

If you find a set that doesn't work, i'll have to hand test them anyway.

If you want to keep a complete document that describes the results for yourself, hey, thats fine too Smiley

Thanks in advance, its not going to be a fun job Smiley

Yeah I can do that. I've gone awol for a while. Decided to take the gf for dinner and a movie. It's 9.30PM here just now and the way things are looking, it'll probably be monday before I can sink my teeth into this.

I did some testing earlier today when at work and the program worked flawlessly. Didn't get a chance to compare against Winols as I only have the demo version on my work laptop.

I managed to find some time to test these today. I had eleven different binaries. I changed one cell in KFZW + changed the first byte to FF in all the files. ME7Sum managed to correct all but two files. The results are in the info included in the archive.

Sorry about the lack of scientific approach. I have zero previous experience in beta testing Smiley Let me know if and what You need done differently. As mentioned earlier, I have tons of free time at work. I sit at my computer all day and usually just watch Family Guy or whatever. I'll gladly put that time to a more meaningful use in the boundaries of my skills.

Thanks! Neither of those look easy to fix right off the bat, unfortunately.

I lied. You can ignore the RSA error in 4D1907558

I was wrong. DO NOT IGNORE RSA errors until ME7Sum has been fully tested, or you are willing to be a test subject.

I haven't figured it out yet RSA checking (and signing) is still very much not working. However, a failed RSA signature will not prevent a file from working, as far as i know, the ECU never checks the RSA signature.

The other image (4D0907558S) i have found a fix for; working on a new release.

RSA checking is very much a problem on some of the 1.8t binarys.

RSA checking is very much a problem on some of the 1.8t binarys.

In that case, I'm going to need some help. The main question being: what area(s) does the RSA signature cover?

I have the rest in place (I think).

v0.1.0 added. (see OP for link).

NEED TESTERS! Prelim RSA support is there, but for some reason, ME7Check does not like the way I correct RSA signatures.. WinOLS seems not to mind.

If you have a bin that has a RSA signature *and you know what you are doing and don't mind being stranded* I could use your help testing...

v0.1.1 released.

This should fix all RSA signature problems.

ALWAYS check your bins with ME7Check.exe.. if you see any errors, DO NOT flash it to your ECU.

Post the bin here and/or email me directly.

v1.0.0 released. See OP for download link

First feature complete (but probably still buggy) version.

Added -s option to dump ecu info only.

You are a beast nye. Congrats!

Every binary I tested it on seemed to work. Sorry I don' have that many cars here Tongue

I can test on a friends car if someone can for sure tell me how to boot mode that ecu. Same chip and pin as ours? I have never looked at the ecu but can take some 16mp pics if anyone needs to see the PCB.

Lmk my friend wants me to make him file anyways, I have found enough info so far as xdf's. I know I told him that MTX wants a different checksum tool for his ecu and he didn't wanna pay for me to have the plug-in. So his SOL right now.
