Hex Editor / Reverse Engineering
XirDecoder is a specialist utility used in the chip-tuning community to decode, decompress and unpack raw ECU firmware images so their calibration data becomes readable and editable in map editors. It targets ECUs whose flash content is stored in a packed or transformed layout, converting the dump into a linear image suitable for tools such as WinOLS. Tuners run it as a pre-processing step before locating injection, boost, torque and emissions maps. Because it works purely at the binary level, it sits alongside hex editors and checksum utilities rather than diagnostic scanners. It is a niche reverse-engineering aid, not a flashing device, so it never reads from or writes to an ECU itself.
Softechpro Solutions works on the firmware image once it is readable, auto-applying DPF/EGR/AdBlue/DTC-off modules and correcting checksums across ~1,400 firmwares, so a decoder like XirDecoder can be a useful upstream step. It complements rather than competes with binary-decoding utilities.
