Here are some updated details on OBDII port tools and software that will allow you to receive car diagnostic information on your Windows PC and Android phone.
I've found cheaper Bluetooth OBDII adapters at around $40 but this one is only $65 and looks to only be about an inch tall vs the cheaper versions that look to be about 4 inches tall. The way that my OBDII port is located and angled I doubt that the bigger ones would fit and not be in the way when I'm getting in and out of my car, just something to keep in mind for others that are considering one of these systems.
So far it looks like Torque is the best software with the most features that is actually out. I'll be ordering up my OBDII Bluetooth Module this week and will post up some more information on these products one I can get to testing them.
