Mine only says zero when I'm not moving, otherwise it is reading different mpg all the time based on throttle position, and engine load. I'm guessing if you still had AFM it would also toggle between V8 and V4.
So I finally had a chance to try that, I selected the "INST ECON V8" leaving town, and when going down hill, it changed to V4 and 99 MPG (I wonder how realistic/accurate that number is"
