Hi all,

I have a VW R32 Golf IV tuned with a custom software. Normally I am able to read all ecus with my MPPS v12 interface. Before the custom software was written to my eeprom, i was able to read the original software, too.

But this time my bin file has only 364KB, not 1024KB. If I try to open the file, I can see "No read file has been encrypted" in the first bytes.

Can you tell me how to decrypt this file? Or what must be done different by reading the ecu?

Thanks in advance! I attached the file, maybe you will have an idea what to do!

Only way i know at the time is use HXD Editor and open Ram of mpps.exe after read from ecu.
Read Ecu until you will be asked for filename to save.
Open mpps.exe RAM in HXD
Scroll to bottom and start to copy up to begin of file.
Then you must remove many lines (send .. and the 20`s) and convert to binary.
But it takes a lot of time....

Yes, the HxD RAM Editor trick works perfect with NOREAD tagged files.

1.) Have a look to your original file with WinOLS or Tuner Pro and write down the first bytes from the hexdump.
2.) Start first the RAM-Editor and second the MPPS software. Be shure that the RAM-Editor runs in backround.
3.) Read your ECU with MPPS.
4.) Switch to the RAM-Editor task without closing MPPS before!
5.) Search for the noted bytes in MPPS RAM area with the RAM-Editor.
6.) If you has find it, marker the next 100000 (hex) bytes (1024k).
7.) Copy and paste the marked bytes into a new file.
8.) Save the file.

Done.

If you want to remove the NOREAD tag, search the saved file for the NOREAD string and overwrite it with "ff" bytes.
Recalculate the checksum and save the file again.

Done... ;)

Hi Guys

Thanks, this works! I searched for the initial header in the RAM dump, marked this point + 1024KB and saved it into a new .bin file.

this thread can be closed, thank you!
