Until you buy a WiFi OBDII port dongle, the only way to run ezOBD
is to download and use a simulator that is of no use except to see how ezOBD works. Without the dongle, you will see a connection error. The dongle is a WiFi transmitter that sends car information to your iPhone and ezOBD is able to display that information. See video . The video was made about a month before our first prototype rolled out so there has been some changes since then.
