Your car will not like it, unlike the EEPROM (and RAM) stuff I got working on it.

I am (slowly) piecing together a python script to do it, via socketcan so the ELM won't be a problem. Currently it is not very dynamic, so it will generate the key from an error message if that's what it receives instead of a seed. But have successfully gotten seed and generated key within the script..
After I get a handle on reading the EEPROM with socketcan I will try for the deeper stuff.
