Here is a little update on the difference between the SG average and CAN-view average. Since my CV lost power for some reason it reset the trip to my last save point which was at around 500 miles into the tank. So what I have been doing the past few days is to reset the trip info on the CV and compare it with the trip MPG on the SG.
What I have found was that on my first trip to work the SG reported about 180MPG and the CV reported 255MPG. 255 is the max the CV can display and could mean 0 gas used or greater than 255MPG. In this case its greater than 255 apparently. On my way home the SG reported 150MPG and the CV reported 220MPG. These numbers were consistent the past few days.
If you were to take the miles driven so far which is 1100 miles and divide it by the percent of the gas used which is %60 you get about 18.333 miles per percent. If I ran my tank down to %0 I would expect to get about 1833 miles on a tank. If that tank was a 10 gallon fill up then my average would be 183MPG which is pretty much spot on to my last CV reading. If it took 11 gallons my average would be 167MPG and is more close to the SG.
Based on what I have seen so far I think the CAN-view will be a lot more accurate for a running average but I'm not sure on which would be more accurate on a trip by trip calculation.

The Hymotion pack is depletion only. It will not accept any regen. I have no clue on what they use to to monitor that information. I would guess the stock prius system still controlls what goes in to the stock battery. I hope that someone with a lot of money tears this Hymotion pack apart to see what all is in there. I would do it but I don't want to risk losing the warranty. Maybe I will in 3 years.
I have been keeping my eye on the SOC gauge on my CAN-view and I notice that when the pack is ON and your accelerating or coasting the sock will be high like in the 75-80 range. When you apply the brake or your at a stop the Hymotion SOC drops back to the stock battery SOC.
The reason for this low mileage was because my pack did not turn on. The LED just flashed at me indicating an error.
