it's a borrowed Scangauge II (thanks Sam!) which I've got no clue how to display o2 sensor data. o2 sensors are not present in the "gauge" portion of the screen and I have no idea which code to punch into the CMD part of the screen to give o2 output. I can get it to tell me which monitors aren't ready, but not much more. It's a fun device, but not a great code scanner.
A google search of how to do this has given me nothing. I only found a youtube vid of a guy in a truck with the Scangauge showing o2 output, not how to make this magic actually happen. I'm *this* close to buying a real scanner. My Palm-based scanner did this, but it has since broken. I'll check on the mazdaspeed forum for that monitor reset. Thanks!
