I understand that the SG does not work for MPG on my hybrid and I don't intend to use it for that. I'm guessing that it is giving me MPG as if the car was gasoline only. I did do some further testing today and it does spike momentarily when I disable the cruise and coast and then heads down. However, even though I was on a flat road and used the cruise set to 50 miles per hour, each time I disabled the cruise it spiked to different values ranging from 130 MPH to 65 MPH. It's becoming obvious I'm not going to make any sense out of this and am getting too fixated on it. :-) I do like the SG for all the other info it gives me.

Eric, do you know if the hybrid model SG Ron is working on will work with all hybrids?
