Best use of a Scangauge?
I've got a Scangauge(II I believe) and at the moment I've got it showing current MPG, AVG MPG, Voltage, and Coolant Temp. My vehicle doesn't have a voltmeter for the alternator and the coolant gauge works but just shows either hot or cold.
Is there a better way to utilize the other two spots in the gauge that would help me on my hypermiling journey?
