Hi All,
I'm an electronics engineering student planning a major design project for the upcoming fall. My group is considering an OBD-II scanner tool, with a nice gui, etc.
Rather than just reading trouble codes and sensor outputs, I'm more interested in modifying tables, etc. I have a '99 Z24 that would be the guinea pig for this. However, based on posts here and at the org, I'm confused as to what's possible and what has already been done.
Is it possible to do writes over the OBDII interface, or has it even been tried, etc? Some people seem to think it's impossible, but I've yet to find evidence to actually back that up. I would very much appreciate if you could help get this newb up to speed.
Thanks!
