I just ordered a Kiwi wifi to plug into one of my cars OBD II port. There are a couple of iPhone apps that wirelessly connect to this through an ad hoc network and I'm wondering if anyone has experience with these apps or can suggest an alternative to consider. The two most highly rated apps appear to be Rev and Dashcommand. What I'm interested in, aside from the real time monitoring transmitted by the cars ECU including speed/tach/fuel pressure and cool custom displays, is an app that can also display engine codes with related information and reset them. Thanks in advance!
