ScangaugeE question
I installed my scangauge e this weekend in my 1999 Escort ZX2 5 sp. My previous three tanks of gas averaged 35 mpg. I adjusted the speed calibration +6% because I have 185 75 14 tires on her and they are 6.2% larger in circumference than stock. On my way home I'll try and calibrate it to my GPS. I also selected the 2.0 engine option. Does the "fill up" help as well? Is this thing really accurate or more like a vacuum gauge that helps you judge your consumption? Is there something that I might have missed? The reason I ask is because I just averaged a door to door commute of 41.5 miles. 1 mile through town. 8 miles on a traffic light infested Rt 1 North in central NJ and 12 miles on the GS parkway north. Traffic on the parkway was light and I hugged the right hand lane averaging between 50-55 mph. What is amazing is how much the economy drops when you lug the engine. Even a tiny bit. It is better to gradually let up on the pedal very slightly as I went up slight inclines letting the car slow down on the way up and then ever so gently getting the speed back on the way down. I wasn't doing this that well without the SG and I'm wondering if this is where the difference is. I doubt it though. I'll callibrate speed to the GPS and recalculate at fill up. It is a fun game but not for the anus holes riding up my bumper. I want to get a definite ave mpg before I delete the PS and AC and see if there is a difference.
