VW 1.8T ME7.5 0261207928

[atd]

Hello everybody.
Making remap I am having problem with checksum. Maybe it was hard day and tomorrow will know what I did wrong but it is strange that Winols see 74 checksums - ols262, but after edit any value -> save the file-> import modified file -> then Winols say wrong checksum and see only 73 checksums. I tried many programs and different modules to count checksums but still importing file to winols cks is wrong.
I have never had this problem with modifying ME7.5.
Can somebody try to edit my attached original file and check cks after?
Thanks in advance.

Thank you Mihai for input. My file like your file has checksumm correct. But try to make modification and reload project to winols. Checksum incomplete. Why? I attach your file with changed two values and incomplete checksum. Is it lack in checksum module? Or strange file which could work with 73 checksum instead of 74 ?

[mihaiservice]

Hi
some problem also with my winols,maybe are something wrong with ols262, also are 3 different version of ME7.5
please take a look on file with chk corrected

With your last file the same situation.
I was trying three different modules for counting cks on me7 without success.

[2xded]

Are You using the original file to create a project and import the file changes In accordance with the help WinOls?

[morgano]

I tried making project from your original, made 2 changes in a map, and save. Here result. Seems all checksums corrected fine.

[nick_f]

maybe something wrong with ols262,need upgrading.in many ME7.5 files do the same.

[atd]

Morgano with your file the same situation. It is something wrong with my OLS262 cks module. When i check this file using another program with checksums me7.5 it shows ok.

[nick_f]

with map3d checksums it shows ok.

Second try with this car. I had no time. Could somebody check my file in Winols ?
I counted checksums by ecm... Audi Me7 2002 module.

[morgano]

-> Bootrom Version = 06.02
-> EPK = 40/1/ME7.5/3/4016.31//24G/Dst04o/080802//
-> Contents of ECUID data table:
- '0261207928' (SSECUHN)
- '1037366497' (SSECUSN)
- '4B0906018DH ' (VAG part number)
- '0004' (VAG sw number)
- '1.8L R4/5VT ' (engine id)
-> Contents of ECUID data table:
- 'HW_MAN004'


-> No errors found. File is OK. *********************

Also my winols detected all 74chk correct.

[atd]

Thank you so much. So ecm seems to have no bugs in ols262 "audi me7 2002" module and make checksums correct instead of forums winols...
Morgano big beer for you!

hi,
i have the same problem with ME 7.5 of a Polo.
winols, titanium and others tell me checksum not correct.
somebody can help me please?

[nick_f]

upload your file here m8

[GianniNOS]

There are the original file and the mod file without checksum correction.
rename the file in .7zip if are problems
thank you

[GabrielMga]

Here is your file, with good checksum man.347601

[GianniNOS]

thank you Gabriel,
but i have again dubt, my ecm titanium give me again error checksum, and I have blocked the ECU once before ...

[2xded]

Yes, you're right about the file EG5J518B_CALC_E42.rar (http://www.digital-kaos.co.uk/forums/attachment.php?attachmentid=347601&d=1450447025).

[GianniNOS]

Doesn't exist a good software?

[morgano]

Sure your nearest local tuner can provide you a good software for your car ;)

thank you

you have done wrong modification if you will change Programcode you must do the chk manual no tool or soft check this correct for code . Or dissable the function with set the variable for checksum check to ok . than you need never more a checksum .

i see some what you not need for more power an this is your problem make your tuning good ;-) and all work

[GianniNOS]

Someone have the hex and a2l of this ecu?
Icezero , do you know what did i do in my file?

[nick_f]

cks ok.

regards

[GianniNOS]

thank you Nick, but the problem remain the same ... :(

[nick_f]

Gianni what meaning remain the same,with cks?

[GianniNOS]

[GianniNOS]

I solved. i wrote te ecu with kess2 in obd mode.
the coorrector of ecm doesn't work good
