The article you mentioned discusses cruising in open loop... My car doesn't do this. Does that mean that I cannot modify the A/F mixture at cruising speeds (55mph)?
You may be able to display the voltage of the 02 sensor using the X-Gauge option, but you will need to know the access code for it. However, I have not seen a specific example of anyone doing this, and the 02 sensors flips back and forth so much that you would need a refresh rate that is faster than the ScanGauge's "4 digital gauge" option. Sooooo, it may not be practical.
