    ME7Sum: https://github.com/nyetwurk/ME7Sum . Reads, analyzes, and fixes the complex proprietary checksum system used in old Bosch ECUs. Checksums in newer control units have mostly gotten simpler as more RAM and CPU were available and "multipoint" schemes were less necessary. Also can correct the very silly ME7.5 RSA signature system, where firmware was signed but self-checked using a public key contained... inside of the firmware. So the key could just be replaced and the firmware re-signed. Interesting read to understand the often arcane proprietary checksum routines manufacturers love to use.
