Factory or aftermarket. If it does, is it a good predictor of your actual MPG?

So far using Our newest econo vehicle I have picked an average travel speed of 64 MPH to be the highest hover reading for best travel speed/mileage. That is based on a calm wind force at 76* F average daily high temperature.

Our vehicle still has low miles as far as break-in terms on moving parts is considered. My daily driver reached near 60K miles before it freed up on the rolling characteristics of the (suspension/drive train) lubed areas. Rather it just drives better with 80+ K miles on the odometer. That stiffness feeling is gone over a 14 year period of use.

I do need to try more changes in travel speed at different daily temps, which I haven't done yet, as for finding a better mileage speed different than 64 MPH. by still using only Our OEM FEM. I do very little reverse backing up so I believe the indicator is often spot on. Idling is limited also on some days during forward set motion. The thing is I don't know if The ECM accounts for motion when in reverse as an energy calculation in MPGs @(any engine RPMs) really Tail-pipe fumes, Ha...... ! HAG-Day!

Yes. Linear Logic Scangauage II on a 2010 Toyota Prius III - the xGauges LOD,GPH/RPM indicates in real time the engine-load when applying pressure to the accelerator which allows the driver a way to optimize a gravity-assisted acceleration during a Driving With Load (DWL) hypermiling session. It provides more precise feedback than hearing and feeling the gas engine run and looking at the Prius' Hybrid System Indicator (HSI) display. The Prius has a high curb weight to horsepower/engine-power ratio (it is a heavy car given its engine power ), so the Prius fuel efficiency performance is more sensitive to the force of gravity. Using DWL on the local hilly roads has increased the fuel efficiency of my Prius by about 20%. It is also a more accurate predictor of fuel efficiency. Yesterday I filled up my gas tank - Over the last two weeks I was able to achieve 59.8 mpg over 549.3 miles using 9.18 gallons of 10% ethanol 87 octane regular gasoline with my 2010 Prius... most 2010 Prius driver in my area are getting about 45 mpg right now ... that is I'm getting about 15 mpg or 33% improvement using the same car ...

Factory-installed. It right now has 19.2 MPG on it. The highest I have seen on it is 27.1 MPG and that was traveling.

Works fine as an economy guide to tailor ones driving habits, I often glance at ours when using cruise control, it helps to determine wind force direction/effects on mileage when driving highway.

Yes and on the warmer recent days the MPG readings are higher, if all 4 tires are aired very proper. I normally aired the front a few lbs. higher, lately, came arround to making all four the same pressure, vehicle rolls better.
Still many chuck-holes/pot holes about, terrible near many business entries/exits, about everywhere locally. March/April wind gusts affect My FEM, and I chose calmer days to drive distances if possible.

Yes, but with qualifications. You must use the same gas station and fill the exact amount each time. Different stations have different shut offs and longer and shorter nozzles. If you over or underfill it will be different from your written log. My suspicions are with the mileage indicator while your driving.
