Anyone have any experience with particular apps / cables connecting your iPhone to your On-Board Diagnostics (OBD) port?
I see an app called GoPoint, but it has a bad review from an F150 owner. I suspect that some apps work well with some vehicles, and not so well with others maybe.
Just curious to see what experience anyone has before I spend any $$$

 

The device probably works ok, but be advised that many early ford trucks were not fully OBD-II compliant, and as a result many scan tools, even higher end consumer models, cannot access the full data streams. An example is my '97 Ford Aerostar. I can read codes, and view some live data, but I cannot read O2 sensors, fuel trims, and several other systems with my Dynoscan software running on a Palm Pilot. I also own a Cornwell OTC Techforce II and it can access all the live data that the Dynoscan cannot. The bad review might be from someone that has an early OBD-II model, or has a blown lighter fuse, and that might be causing problems. If you truck is older than about 2001, the generic readers might not be able to read all the data, and if your lighter fuse is blown, you might not be able to connect at all.
