Here are my scangauge results when I set the engine parameter to be 2.0 liter :
Based on the above, I think your Kiwi should report well above 100 MPG @ 55 MPH. What you will notice is that the Scangauge is reporting an MPG that is about 3.3 times the current MPH. I believe the ratio will change in inverse proportion to the size of the engine.
