Greetings to you and thanks for the welcome. I too have arrived at 'just driving the darned thing' in the city. However, I'm about to embark on my first long distance trip; lasting 12 hours; and wanted to maximize MPG. So, I've been reading you; the experts, to gain valuable insight. A month ago, I decided to leave my OBDLink BT adapter in the wife's car and get a new OBD Wi-Fi for the trip. Didn't wanna step on the bluetooth channel for car audio and other BT functions. I had the scare of my life. Off topic I know but... I had scantool's app on my android and was running at 60 MPH. This was the third driving cycle for the Wi-Fi adapter. Suddenly, the car throws an error on the dash urging me to pull off safely. I thought I had power but NO, I had to glide to a stop off the shoulder. Freaked out a bit, with the South Florida idiots whizzing by, I quickly shut the car off, unplugged the Wi-Fi adapter, waited another minute, and restarted the c-max. Thankfully, I drove off without incident. The folks at scantool had me perform the all-popular adapter reset; and I've been fine since. I don't seem to have many PIDs with OBDLink; may have to boot up Torque and give it a shot. I would have thought I'd get more insight into the vehicle as compared to my old '03 Expy. Anyway, thanks for the info. Clearly, you are a master of the c-max. I'm still havin' too much fun saving 180 bucks a month on fuel :) mike
