They do different things.

**WinOLS** is a calibration tool — maps, modification, checksum handling.

**Ghidra** is a reverse engineering tool — firmware analysis, algorithm understanding.

Ghidra tells you _why_ the maps work the way they do. WinOLS is where you _make the changes_.

**The realistic path:** Learn WinOLS first. Then add Ghidra to extend what you can do.

In [Ghidra Fundamental](https://tunersguild.com/courses/tricore-reverse-engineering/?utm_source=forum&utm_medium=post&utm_campaign=topic-43&utm_content=cta), we assume you already understand the map level. The course is designed for working calibrators.
