No spaces in path names allowed, e.g. Tunerpro Files won't work.  The prog thinks 'Files' is the name of the bin, and, of course, it isn't.

I am having issues trying to run a bigger MAF on this ecu B0906018P. ME7 sum says it corrected everything and it is good, but ME7check says it fails.

Romsys checksum failure(s) found
-> Found 1 error!!!   *******************************

Oh it worked! TY sir! Kicking myself for not thinking of that.   

I get the same problem, I have to run ME7Sum twice to fix all checksums.
The bins are more or less stock 8D0907551K and Q. Just a couple of codewords changed (CW_CAR_R_0___A = 0 on first try and the a few more). If you need test files I can post one of these.

Here is a K-bin and a Q-bin and corresponding output from me7check and me7sum

That software was never completed and
1) does not compute all the checksums
2) does not automatically locate checksum locations.

Hello, is MD5 hash failure same as RSA failure?

Hope this thread is still alive and hopefully I can get some info.

I have a problem with a file for a 2002 S3 BAM 8N0906018BP. I use TunerPro with the MTX plugin. I have made only one simple change to the ori file, as a proof of concept and I get this when I run ME7Check:

RSA signature failure found
-> Found 1 error!!!   *******************************

However! When I run ME7Sum on the same file, I get what I can identify as a md5 hash error, and not the RSA:

I have attached the binary. Thanks in advance and sorry if I failed to find an answer to this, but I am pretty sure I read the whole forum already...
