I wrote something similar in the 1990s. Except, I had to write the TUI library myself (in x86 assembler) since nothing like what I needed existed at the time.

I wrote something similar in the 1990s. Except, I had to write the TUI library myself (in x86 assembler) since nothing like what I needed existed at the time. I was working on a project to do ECU performance curve remapping for a rally driver friend, so mine had additional features like the ability to export memory segments as .m files for plotting curves in Matlab. I watched a video about ECU remapping (on a modern processor) yesterday, and the guy started by using the OBD port to get access to the system. I had to physically desolder the EPROM from the board to dump it back in the day. The kids today have it far too easy.
