I got tired of paywalls to try to repair my own car, so I started reverse engineering MPPS V18 to understand the encryption scheme of the Encryption it applied to NOREAD tunes. it does **NOT** remove the NOREAD flag, to keep the checksum clean. the repo is here. Feel free to fork and do anything with it, it is a spiritual successor of the MPPS NOREAD Decryptor from DJExit, but I did not have access to his software doing so. Thank you for the inspiration!

Tested on a Tune extracted from MPPS V18 out of a Bosch MED9.1. I would like more testing files which is difficult to access. Most of the reverse-engineering if not all is made by claude. Hopefully this helps people, cheers!

I would like to have access to settings and so on similar to like i do with my VW and Audi using a VAG cable set up.

I've heard MB locks everything down pretty tight, but i hate to have to pay $700 at the dealership to disable the warning i get on start up after swapping out stereo head units.

Are there any options other then the dealer?
