So after seeing and working with the info on this thread: http://nefariousmotorsports.com/forum/index.php?topic=3504.0, I went and created a web based hex calculator that will figure out the hex edits needed to change the mileage to whatever you'd like.

MK3 Mileage Tool: http://tools.varpartsma.com/mk3calc

After calculating the edits needed, it can also patch an uploaded MK3 .bin file for you and allow you to download it.

I know this is for older clusters and might not be all that useful but I was going to make it for myself anyway and figured that I'd just share it in case it can help someone else out.

If you notice any bugs or have any feedback, please let me know! Also, if anyone wants the code so that it can be ported over to another language (currently it's just PHP) or made into a command line tool, let me know.

Thanks to Drehkraft, AmIdYfReAk, and jaspersk for their initial research in the other thread!

- Project is still alive! Fixed a bug where the bytes were being flipped incorrectly. More features/updates/fixes may come with time.
  Please let me know if you find any bugs or have any feature ideas!

Updated: 1/8/2016
- Added the ability to upload and modify "Bubble" Cluster bins as they store the mileage slightly different.
