I've been interested in getting at some of the detailed info my car knows, that I don't. Things like throttle position and load to start with. A Scangauge is a not-insignificant investment... However, I have several old smartphones and a PDA hanging around. A little digging around on the interwebs revealed that there are Bluetooth OBD plugins that will interface with the right hardware, and there is dedicated software written for the older Windows Mobile phones. So, I have a Bluetooth OBD plugin on order (24 bucks), due to arrive Tuesday, and I've resurrected my old Touch Pro 2 with an in-car charger. It's set up on the dash just to the right of the upper arc of the display on the HCH-II, so it's easy to glance over without taking my eyes off the road. I have two free software packages installed and I'll see how they each work out. Interestingly enough it's also a perfect dash-cam should I want it to be I've also got it to use WIFI to sync my calendar so while I'm at home it will stay updated through the home wifi and I can review (with voice commands) my daily schedule on the road. And it gives me a pretty weather display on the main screen too. Yes, yes, I am a nerd. Of course with the HCH I still have a second power socket available for other things. Like the inverter I have stashed in the center console.... I'll try to throw up some pics of the setup, and I'll be updating the thread with the story as it unfolds. I figured this was a nice way to keep what is a pretty good piece of hardware performing a rather useful function.
