usage with explorer context menu
win+r
regedit
HKEY_CLASSES_ROOT\*\shell
make new dir name as you want ('fix cs' for example)
make new dir inside previous name it 'command'
so your final path should be \HKEY_CLASSES_ROOT\*\shell\fix cs\command
change default value at the right side to
C:\\windows\\system32\\cmd /k C:\VW\me7check\me7sum.exe "%1" "%1" & pause & C:\VW\me7check\me7check.exe "%1" & pause & pause & exit
with path changes to yours
now right click on a flash file, select 'fix cs'

Done quite a few updates today! It can now identify a few more variants/strains of routine as well as detecting and then pulling the correct DPPx register out of a given rom. This makes it quite a bit easier to set things up for correct reversing. Also added the ability to do the calculations of the multipoints now too as well as finding the xorCalcuationTable in a given rom (if it exists) and dumping its xortable too  ... Have fun Here's what dppx analysis looks like... Loaded ROM: Tool in 1Mb Mode
-[ DPPx Setup Analysis ]-----------------------------------------------------------------
>>> Scanning for Main ROM DPPx setup #1 [to extract dpp0, dpp1, dpp2, dpp3 from rom]
main rom dppX byte sequence #1 found at offset=0x64a6.
dpp0: 0x0000
dpp1: 0x0205
dpp2: 0x00e0
dpp3: 0x0003 (DPP3 is always 3, otherwise accessing CPU register area not possible)
Argh, revisited this again today. What a mess :/ I wish you had built on my code so i could merge this in more easily |

I calculated the checksums with the help of the me7sum tool and flashed it into the car, but it killed the control unit. Then I checked it with WinOLS and it detected bad checksums. Where can there be a mistake? I am attaching files ..

Thanks for reporting this. Looks like me7sum cannot correct that bin.
It could be there are RSA checks me7sum isn't detecting.

It worked for 16 edits in the software, but only in 17 it did not calculate correctly. Could it be that the _um maps have changed?

There is no reason to ever change _UM maps.
Most likely with your edit you caused chain reset of ECU.
Nothing to do with checksum, everything to do with your stupidity in this case.

Sometimes i get the same Problem so just Double Check the Corrected file and then it should work perfect i never ever had any kind of issues with me7sum tool
Just try after correction with the me7check the file after that sum it again

Hello, A while ago on some AudiA4 forum I found 2 files for 8E0909518AQ - ORI and RearO2offchk. I took ORI file, and changed appropriate maps to disable rear O2 sensor (just to verify my map pack cause I have the same ECU). Then compared my changes with RearO2offchk - changes were exactly the same so I exported the file (KatOff_test) and checksumed it with me7sum (had to do it twice, after the 1st time there was still 1 error). Now ME7Check doesn't report any errors on my file (KatOff_test_chksum2) but it is different than the RearO2offchk from the forum for which me7check is also not reporting any errorrs (I see differences in 7 "sections" of the dump). Can somebody verify these files if chksums are correct? Is it possible that chksums are correct but files are different? Or maybe me7sum/check is not working with this ECU? Attaching files and full logs from me7sum in the zip file (exceeding max lenght of post). Appreciate any reply  ORI (downloaded)ME7Check v1.12 (c) mki, 06/2004-05/2012

1) what version of me7sum? Make sure you are using the latest.
2) show the output of me7sum or its impossible to guess whats going on.

Hi Nyet, as mentioned in my post full output was attached in the zip file because I couldn't put it to the post due to char limit. However here it is: 1st correctionME7Sum (v1.1.1) [Management tool for Bosch ME7.x firmwares]

Hi,
I need to calculate checksum for a Smart ECU (MEG 1.1). I tried the lastest version of ME7Sum but it doesn't find anything useful in the bin file.
What do you think ? Is it doable or not to make it work ?
I know absolutely nothing about the checksums that are used in these ECUs.

Sadly, a completely different ECU in almost every way that matters. |
