OBD route will be much better once the basics are in place because it's just a matter of processing collected data!

I've got the RS-232 to ISO interface adaptor, so it's not even a hard ware issue involved, it's just software!

I'd need completely new hardware to interface direct to components like the speedo, and this hardware would be different for each car, the OBD standard should be more generic!

The latest trials were last night, but it looks like it's a problem understanding the car system more than anything else at this stage!



Thanks for your comments though!
