Tool comparison
010 Editor by SweetScape Software is a professional hex and text editor best known for its Binary Templates: small scripts written in a C-like language that parse a binary file into named, typed fields you can read and edit as a structured tree. This makes it powerful for reverse engineering firmware, container formats, and calibration data where offsets and record layouts repeat. It handles very large files, offers a scriptable engine for repetitive edits, file comparison, and a wide range of checksum/hash functions. ECU researchers use templates to lay maps, headers, and identifiers over a raw dump so edits become field-level rather than blind byte pokes. It runs on Windows, macOS, and Linux and is popular across the wider RE community.
Ghidra is a free, open-source software reverse-engineering framework released by the U.S. National Security Agency. It provides a disassembler, an interactive decompiler that recovers C-like pseudocode, cross-references, scripting in Java and Python, and collaborative project support. It supports a broad set of processor architectures, including ones found in automotive ECUs such as PowerPC, and can be extended with SLEIGH processor definitions for others like Infineon TriCore. In ECU research it is used to disassemble and decompile firmware, understand control logic, locate map-access routines, checksum algorithms, and diagnostic/DTC handling, and to document memory layout. It is a heavyweight, expert-level tool for people building tuning solutions and understanding how an ECU actually computes, not an end-user remapping application.
010 Editor (Hex Editor / Reverse Engineering, SweetScape Software) and Ghidra (Hex Editor / Reverse Engineering, NSA (open source)) compete in the same space, so the choice comes down to coverage, workflow and price for your specific ECUs.
