still trying to figure out how you are getting that high of mileage. i'm stumped - unless you run around at 50-55 mph.
i can reach 43-46 mpg on my commute if i keep a constant 67 mph, as i've found that i can keep it on cruise in rush hour for the most part and not worry about hitting the brakes all the time, stop and go. (not getting run over to bad...but definitely in the right lanes!). i too run with t/c off and econ off (per your recommendations). not sure how to reset the ECU as you have mentioned before. i run pure gas (ethanol free) 91 octane (yes, it costs more, but definitely better mileage - just not as good as you).

Been averaging around 31mpg mixed driving on 93 octane. Not shabbyfor an Si.
I use gasoline with 2 octane higher then you and is top tier which has friction modifiers and dont you have lots of hills? If I remember right KC is hilly so engine loads with A/C and or lights will use more fuel. Illinois is not exactly flat but because living near the lake there is more wind which can help push the car at least in one direction.

Oh I'm convinced that the ECU actively re-learns each time I turn on my car. For example, if I don't push my car right away, from a cold start, then it doesn't respond as nicely if I were to have driven it a little bit more aggressively right from the start. And no I don't mean flooring it on a cold start. I think the ECU acts differently and this effects MPG
