Default Re: Comprehensive MSS54/MSS54HP DME Information

How to add E36 M3, E39 M5, and E46 M3 checksum correction to TunerPro v5.00.8075 (current as of this post):
  1. Download checksum.exe (unary Windows binary checksum correction command line tool for all aforementioned platforms)
  2. I placed it on the desktop, you can place it wherever you like, as long as you point to it correctly in the Custom Tools definition.
  3. Open TunerPro, open the proper XDF, open your binary calibration file, make the desired edits, and then save your binary file.
  4. Click on Tools -> Custom Tools -> Edit Custom Tools...

  5. Click New

  6. Under Menu Text, enter 'MSS50/MSS52/MSS54/MSS54HP Checksum Correction'
  7. Under Tool Path, click Browse, and point to the downloaded checksum.exe executable
  8. Under Cmd Line Params, enter exactly as follows:
    -i="$(CurBinPath)" -s -w

  9. Click OK
  10. Click Apply

  11. Click OK
  12. Now Click Tools -> Custom Tools -> MSS50/MSS52/MSS54/MSS54HP Checksum Correction

A small black box will open, execute the tool with the included path to your binary, and subsequently close. Your file will be corrected inline, which is to say that your saved .bin file will now have corrected checksums and be ready to flash.

It should go without saying, but if you make more changes in TunerPro thereafter, the checksums will no longer be correct and you will need to run the tool again.
