Extend the Life of Your Car
I just purchased an ElmScan 5 OBD II wireless scan tool to peek into the dynamics of my engine. That tool, coupled with my Nokia N800 and some cool software called CarMan sent my mind wandering.
I am able to capture the engine load at a point in time. What if I calculate an average load for a commonly traveled route? I can then take variations of that route and determine which path minimizes the impact to the car. I could factor a lot of variables including time, distance, average engine load, gas consumption, frustration, etc. I could then determine a set of heuristics that could suggest the optimal path.
This could be useful for frequently traveled routes like to and from work daily. Or any other profession that does a fair amount of repetitive automobile travel. I believe the software could just sit there gathering information with little input from the user. This would allow it to collect a vast amunt of info and make decent determintions based on user preferences.

I’m considering an N800 specifically for use with Carman. Were you able to pull instantaneous and average consumption rates for fuel? It’s not clear what codes the Carman is able to process but these are the most important ones for me.
