Pulled this file of an audi A4 1.8tq -01.
been using MTX ME7 plugins for a ton of different ecus, allways worked 100%, and even this one says it is compatible, and the plugin "fixes" the checksums..
..only when i run me7check on the file it tells me "1 data area checksum failures found".. hmm! =/
all i did was up 1 point in the LDRXN map, and this happens.. now, i dont dare to flash it untill ive worked this out, WHY it cant correct this file.
i ran it thru me7fix, and it couldnt identify this as a me7.5 algoritm.. the mtx plugin said it should be compatible tho..
i read it using the 29f800 mem template, and the original files states NO errors.. i also tried reading it with 29f800bb, and this also states no errors.
what to do, is there something wrong with the file? someone else who could test with the MTX?

ME7Check v1.11 (c) mki, 06/2004-07/2011 Checking file d:\Motronic 7.5\!tuning\Gson\8E0906018B_A4_01_1.8TQ_mod.bin (size 1048576) Reading Version Strings... -> Bootrom Version = 05.12 -> EPK = 40/1/ME7.5/5/4016.32//24e/Dst04o/190101// -> Contents of ECUID data table: - '0261206868' (SSECUHN) - '1037360990' (SSECUSN) - '8E0906018B ' (VAG part number) - '0004' (VAG sw number) - '1.8L R4/5VT ' (engine id) -> Contents of ECUID data table: - 'HW_MAN004' Data area checksum failure(s) found -> Found 1 error!!! ******************************* |

Well the original and 800bb files are identical, so no problems there, but comparing the changes between the original and modified files, i cant immediately see what differences between the files could be in an ldrxn map... What address are you changing for ldrxn?
I have differences at:
1f68e (2)
1fc76 (6)
1fe46 (6)
93000 (4)
939f8 (1)
fffe0 (32)

i have the ldrxn map located at 1F682, so ill bet the 1F68E is the only part that i have changed.. i just raised a value and saved to see if it would correct the checksum, but me7check gives me errors no matter what i do.. =/

Yep, so it is  Here's one that checks out ok, with the 1f68e modification, made from the original file. Would be intresting to see if MTX corrects any further changes ok though... Cheers |

Hmm indeed... Guess you've found a bug in the MTX checksum routine then. Email their support & see where you get to, but in the mean time if you need a checksum done, just post up the un-mtx'd file with the mods & i'll sort it for you.

ive sent mr.Salvatore a mail about this. ugh, thats so typical for my ecus.. my 032HN ecu was also the first one to encounter a bug in the MTX me7-2002 plugin, but that is corrected now in the new plugin-version..  thanks for the offer, thats great ..but i need the ability to tune things right away while im in the car.. and i wouldnt want to post my "top secret tuning techniques" for anyone to look at here.. someone might blow an engine..! hehe (there is also some custom code going into this ecu.. which is why i need to be able to alter things right away.. lets hope MTX will look at it asap) |

so.. reply back from MTX saying there shouldnt be anything wrong with the file, but instead the me7check app.. which i doubt, since sweegies corrected file shows NO errors and the MTX plugin corrected one shows 1 error in data area. MTX also tried using winOLS and made the same mod and saved and got the same result as with the MTX-plugin, that is 1 error in data area. so, question is, what differs in these two files checksum tables, the same mod is made to both, only one point in the LDRXN map is raised, but one file has a bad checksum and the other seems ok. i dont know if i dare to flash it untill i know for certain that the checksum plugin are working and the sums are 100% correct.. anyone who could compare the checksums of the 2 files and perhaps find out what the MTX plugin(and apparently winOLS) is missing? ..any help with this is much appreciated! |

For yucks, can you try ME7Sum (see my sig)?
There still some CRC things its missing, but it would be interesting to see..

If you bin diff the two files, they probably have differences in that region; as i said, i think there are definitely gaps in ME7Sum's coverage... it could be that MTX is correcting something in 0x090000-0x093FFF that ME7Sum doesn't know how to correct  Bummer. Doesn't surprise me... I hope someday somebody can help me fix ME7Sum. |

nyet: there are NO differences in that region, that i can find, and the "corrected" file is NOT corrected using me7sum.. also, the corrected file is verified to be 100% working.
from what i can tell the MTX plugin is calculating this sum wrong, and even me7sum flags it as OK, which seems strange.. two different checksums cannot be OK, then they arent checksums.. forwarded this to MTX, but no reply as of yet.
