The above heading will be edited as I go along and any additional "helpful" info will be most, greatly appreciated as a growing open discussion on how to create a simple to use, hand held, stand alone scanner, data recorder, live data capable and (in some very rare occasions) a bi directional device. SO first off, I will start with a few disclaimers that may dissuade any bogus attempts to dissuade me from my initial quest. So, what was my initial quest? I wanted something that had a fast baud rate with no bells and whistles with just very few but very important PID data's. The one's I was looking for were fuel trims, and o2 switching. I could care less about air intake temp if the app does not display ECT. So I needed something that could show me the general situation of an engine at a glance with a high baud rate. All this either by wifi or BT. (blue tooth) Some apps I tried, I could literally feel my beard grow waiting for the "live" data.
