Looks like two places are no-opped out by ecufix. 38289c38289

I'm assuming those are the RSA functions: question is, what is wrong with my RSA correction? Is there actually a separate public key stored somewhere in the ECU that I am unaware of, that is paired with a private key that only Audi has? ME7Sum generates its own key pair (self sign)... perhaps that is not sufficient. |

According to my sources, the custom NLS code is interfering with the RSA checking done by the ECU because it disturbs ram location 384FF0
Changing it to an unused (for real) location (e.g. 386000) should fix the problem, and should not require the RSA checking to be disabled entirely.

We can fix it  HOWEVER! Trying to find unused RAM without disassembling the files will be difficult. The solution implemented starting with version 0.4 is that you can change the counter variable by specifying the address to use in your argument. example: launch.exe ecu.bin ecu.ecu offset_code offset_variable 0x384FF0 Please don't forget, you need to specify the offsets for locations manualy if you want to use it!  |

We can fix it GREAT work, thanks dude! Trying to find unused RAM without disassembling the files will be difficult.
Not just difficult, i can't think of a good way to know for sure... other than using ME7L to log values in various RAM location candidates and see if they change throughout a long drive. |

Thanks But i think the easiest way is if we create a list of addresses that are known working, and in which software. |

How can I be sure that the script won't cause any errors? Everytime I start my car I have in my mind this.. :/ |

If there was a problem you would have seen it in the first 2 3 days of driving or after 70 80+ km. I assume you did more then that so there will not be such a problem.I am trying to find out at the moment what is wrongon some version with rsa.

I don't think this is a good idea. Look, there is absolutely no reason NLS is a must have. If you can't get NLS working correctly, and it causes problems, don't use it. You can easily use ME7Logger to log ram areas and see if various address contents change over time. Try a different ram location. |

I am getting this error 16985 on one car with NLS/LC.
Can anyobdy confirm if ME7Sum works in this case? I have double checked, but always says: No errors found. But after 30-50km again this error.

ME7Sum (nor any other utility) will not help if you screwed up your ASM patch. |

Hello,
Today I have used auto add script found here:http://nefariousmotorsports.com/forum/index.php?topic=3349.0 patched my ECU .bin and corrected checksums using me7sum. 9 checksums where corrected
Before correction I have checked the file with me7check and 9 errors where found however after me7sum no error could be found.
I have not tried the file yet..
It is a 1.8t HS file
Could somebody owning ecufix check my file and correct if still not OK?
Thank you in Advance,
Regard
OK It looks like my file does not have RSA so I'm removing the attachment.
