Hex Editor / Reverse Engineering
Notepad++ is a free, open-source source-code and text editor for Windows created by Don Ho, widely used for editing scripts, configuration files, logs, and CSV data. It is not a binary editor by default, but the popular HEX-Editor plugin adds a byte-level view so users can inspect and lightly patch binary files. In tuning workflows it is most useful for authoring and editing helper scripts, reading exported logs and reports, comparing text files with the Compare plugin, and, via the hex plugin, glancing at raw dumps. Its tabbed interface, syntax highlighting, regex search, and plugin ecosystem make it a convenient utility around a tuning toolchain, even though dedicated hex editors are better for serious firmware work.
Notepad++ is a general-purpose editor around the edges of a tuning setup; Softechpro does the ECU-file changes and checksum fixes itself, so Notepad++ is best kept for scripts, logs, and notes rather than binary tuning.
