Does anyone have any experience with ODB-II codes (http://en.wikipedia.org/wiki/On-board_diagnostics) and/or have any .net code available for reading information from an ODB unit? I'm having trouble reading data from my car. I'm trying to follow the spec as outlined in various wikipedia articles and based have search for solutions on forum postings on mp3car.com (http://www.mp3car.com/vbulletin/engine-management-obd-ii-engine-diagnostics-etc/49332-net-code-obd-ii.html). I really just want to get some simple data to begin with (RPM, Speed, Fuel usage ...etc). Any insight, links or help would be greatly appreciated.
By the way, the app is being done in VB.net so examples in VB would be super - I have found a C library or two that I'm going to be checking out, but reading through someone else's C code can be a bit tough.
Thanks.
