Hi Milkman,
Sorry about not responding earlier but I've been gone. We love our Scangauge II. The readouts include:fuel system loop status (when O2 sensor is controlling mixture),cost of fuel per mile,Intake-air-temp,water temp, gallons/hr,ignition timing,engine loading,miles /gallon (instantaneous or average), miles per hour, manifold absolute pressure, RPM, throttle position setting and battery voltage. On a trip basis it gives: maximum speed,max coolant temp,max engine RPM, aver speed, aver fuel economy,trip miles,trip time elapsed,trip fuel used,trip fuel cost. Tank and Current Day info shows fuel used since last fill-up, fuel remaining, distance since last fill-up, dist remaining until empty, time driven since last fill-up, time remaining until empty. These trip and day readings can be setup as gauges using the xgauge function. The scangauge also reads any error codes that may occur. One sets the scangauge for 1 liter engine, 8 gallon gas tan (so you never run out) and the correct cutoff.
We find it really helpful and very informative. I definitely think it helps us be aware of our driving habits and how we can change them to get better gas milage, without negatively affecting our enjoyment.
