fig - when you find it, could you post some pics?
Anand (from the s3 forum?) is developing some pda software to run off the odb2 port and display various car parameters in realtime. Sounds like an amazing piece of kit to me, especially for track day use (i'm hoping he includes a data/telemetry logger in it!).
He's even mentioned having a bluetooth connection between the port and the pda but having never seen the port, I'm not sure how feasible that would be.
Any techies out there that could comment/advise?
