Screenshots and video tutorials

**Live Scrolling Checksums** - Explore multiple checksum logics while navigating through hex data. Instantly identify checksum regions and their locations - essential for hex exploration.

HexTool Pro — Simos 18.1 IMMO editor and Micronas CDC32xx cluster editor open over the dual-pane hex view — **Dedicated IMMO & Mileage Editors** - Work several modules at once, straight over the hex view. Here the Simos 18.1 IMMO editor extracts VIN, CS, MAC and FAZIT ready for an IMMO clone, while the Micronas CDC32xx editor validates the EEPROM against the flash and lays out keys, PIN, status and mileage - no offset hunting required.

Qwojtsoft Calibrator — mileage codec registry with hex diff preview — **Qwojtsoft Calibrator - built into Pro** - Pick the vehicle straight from the codec registry (219 codecs and counting), read the decoded mileage in km or miles, and set the new value. The Hex Diff panes show exactly which bytes change before you save - no offsets to hunt for, no codec to build.
