still working on this, ran into a few road blocks but working them out, I have been able to connect to elm327 and to the van,
having a problem trying to figure out how to wait for a reply from elm before firing next command.
Anyone out there who can help or would like to join me in this project let me know.
Would love to share source codes which each other to get further onlong in project.
I have found a class module from
http://www.apeirokalia.com/elm323/ but have not figured out how to use it yet.
