ezOBD is an OBD scanner iPhone app.  Currently, it only provides diagnostic type information and as our community matures, we hope to include information on how to improve the operation of a vehicle in terms of performance, economy and what type of fuel it can accept.

Many of the Parameter ID codes can be found on Wikipedia.  These codes represent information that a cars Engine Control Module (ECM) provides about the current state of the car.
