Hex Editor / Reverse Engineering
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.
Ghidra is how researchers work out an ECU's checksum and calibration logic in the first place; Softechpro turns that kind of understanding into automatic modules and checksum correction for everyday users, and does not replace deep reverse-engineering work like Ghidra enables.
