Hi all; I've began using a SG2 with my Prius2010, and I have a few questions: 1. I seem to be able to pulse and glide at higher speeds, but this happens only 50% of the time. I can pulse to 65MPH and then when I glide, my SG shows 9999mpg. The problem is that sometimes the prius would just refuse to turn off the ICE at speeds higher than 41-42mph. I've learned that if I restart the car, it often helps. Any ideas how to achieve this consistently? 2. When I do regular P&G the SG always shows 0.02GPH use. The funny thing is that when I achieve the above highway P&G it shows 0.00gph. Anyone can explain what's going on here? 3. Is there a way for me to know what was the lifetime MPGs for the prius I own (If I didn't log all my driving?) Thanks!
