Kind of a dead thread, isn't it? Did I read the heading right that you can hook up your iphone to read OBDII codes? Or am I an idiot?
Well, not yet. Or at least, not as a result of PriusChat coders. This forum - and the sister forums - were designed to let PriusChatters write some phone apps to allow plugging the phone into the OBDII port. There are some apps available for sale already, but most of those are geared for racing and performance. The thought here was that while still performing some of that information, we would also give the user the ability to get the hybrid-specific information and other information a hypermiler could use to improve overall mileage. The more active of the forums is the HTC one, I think.
