It would be an interesting reverse engineering challenge, 20 years down the road when it is more accessible.

I spent 1.5+ years on my 2005 car's ECU to reverse engineer most of the maps, since no public tuning files existed. I then went and spent 1 year on the TCM for which again, no tuning files existed. With the patent files, I was able to discover the algorithms and maps, and am even in IDA as I write this, and in Ghidra emulating some code.
