RomRaider

I want to read and probably write many many tables, and being python my loyal copilot, I rather do it from python.
I'm super ignorant on java, but Log4j aside, and this project in particular looks too complex for me to fool around at the java level.
Never used RPA before, but at moment looks like my best option, just found a package that drives TagUI.

If you know or vaguely imagine other options for programmatic read/write of tables, please let me know! (almost everything would be better than RPA)

I don't understand.... most of your post, but I wrote a J2534 library in Python (Windows only for the time being) here: https://github.com/Shamtam/PyJ2534

I started working on a Python-based RomRaider "replacement" but it's been stagnant for almost a year now. Hoping to get back to it in the coming months. If any of that is useful for you, you can find it here: https://github.com/Shamtam/PyRRhic

wow, looks like is exactly what I was looking for .
I just want to load/write some tables from/to rom binaries, mainly ignition timings.

Sounds like you want ECUFlash then... if you're trying to flash your ECU, that's the only "free" option (requires a Tactrix OpenPort)
