After recently installing a ScanaGuage-II in our rig, we went on a 600 mile 24 hour round-trip journey to attend an out of state family funeral.
I quickly settled into displaying
- Average MPG
- Real Time MPG (I forget what it's actually called in the display)
- MPH
- RPM
Our trip out we averaged 11.8 MPG
Our trip back, we averaged 10.5 MPG
To get those numbers, we had to reduce our cruising speed to 60 MPH. There was a steady wind from the north/west which played on those figures.
On our up-coming 4 week trip, I'll be tracking fuel economy the old fashion way and see how it compares.
I have yet to read through the manual, but the MPG figure on the SG-II resets to zero with each engine start-up. Is there a way to accumulate Trip-Average data over the course of 4 weeks?
As you can see, I bought it to monitor fuel economy to drive smarter.
ADDING ON 10/3/2013
During our 4 week trip last August, I changed RPM to TPS (throttle position sensor). TPS ranges from 12 to 76. At 12 my foot is off the gas pedal. At 76, the pedal is plastered to the floor. I quickly learned how much gas I am giving by the position of the gas pedal.
