Flashing tools for VW AG control units over UDS. Compression, encryption, RSA bypass, and checksums are supported for Simos18.1/6/10, DQ250-MQB, DQ381-MQB, and Haldex4Motion-Gen5-MQB.
These are policy-driven snapshot management and replication tools which use OpenZFS for underlying next-gen storage. (Btrfs support plans are shelved unless and until btrfs becomes reliable.)
