Closing this one out since it's not really an issue in the decompressor/decryptor.
Please let me know if my information was helpful. That control module looks like EDC17?
I don't do a lot of research into them, but usually these older Bosch control modules used some form of primitive XOR scrambling, sometimes just rolling-XOR with a cutesy fixed code or 255-byte key. It's hard to say with your specific module but that's where I'd start. Cryptanalysis (try to find repeating/known data, xor backwards) or disassembling the flash handler are usually the best bet for figuring these out, or trying to find them documented elsewhere.
