Hi Forum. Since purchasing this truck I've wanted access to whatever data was available on the assorted buses and diagnostic interfaces. I tried an inexpensive device from Scantool.net only to learn after purchasing that very few of the parameter IDs ( PID ) on J1850 VPW were known or published. I then tried Torque app for Android with basically the same result. So, is purchasing this scan tool the only way to get access to this data ? I'm particularly interested in creating my own interface so does this scanner provide me with any API ( e.g. C, AT ) that would allow me to do so ?
