___I didn’t own my Insight before all the ECU updates were applied so I cannot tell you a before/after effect but having the 2003 update/recall performed before I picked her up, I am receiving excellent mileage w/ most 90 + mile segments in the high 90’s/low 100’s myself as of late myself.
___Not that I wouldn’t like a bit more lean burn or better fuel economy somehow but I don’t think there was much of a hit w/ the last 2 flashes or I wouldn’t be receiving the mileage I have as of late I don’t think?
___Good Luck

I suppose that if we could rig the "map sensor" to make it read more vacum pressure as if the gas pedal was less pressed, the ECM would give the lean burn. It would think that it is not as much under load.
Or is there more to this.
The map sensor is the Manifold Absolute Pressure sensor.
A much better "mod" would reprogram the ECU to default to allowing assist while in lean burn...This is possible now, but only through some very specific throttle pedal techniques...It should come naturally to the car.

What are these techniques?

The encephalographic cerebral memory (ECM - (your brain)) must be reprogrammed to obtain maximum MPG. The technique is to use the memory reprogramming device on the dash (the MPG indicator). <VBG>
The chemistry an physics of combustion are the limiting factors in why this window is soooo narrow. Slowing down widens the window. 50-55 mph seems optimal for most conditions. Lighter, smaller, and slower is the only way to significantly improve an internal combustion engine driven passenger car's MPG. Bigger, heavier and reasonably fast multi-passenger vehicles, e.g. trains and buses, have a much higher passenger mile per gallon equivalent.
An internal combustion engine is simply an air pump. Air is expanded by burning a fuel in a closed chamber. There is a mechanical means where-by this expanding air is made to do work. The inefficiencies in the conversion of energy is where the losses are. The "energy" is the temperature difference between the heated air inside the combustion chamber and the cooler air outside. There are no efficient means to convert small temperature energy potentials to mechanical force, hence the MPG we get. More than half of the heat potential of gasoline is being wasted. There are means to collect this energy but none are suitable for a car and none could recover a significant enough amount of energy to even "pay" for their manufacture. In other words you would spend more energy in manufacturing and installing such devices than is recoverable, a net increase in consumption.
Fuel cells are the only system on the horizon that promises a more efficient conversion (read better equivalent MPG).
We are drunk on cheap energy. And rarely realize the huge amount of work that is being done for us to move down the road at 60 MPH.
I am constantly amazed that my car can propel itself and me back and forth to work using the chemical energy in less than a milk-jug of gas. (over 64 miles up and down hills all the way).
Even more so knowing the efficiency (or lack thereof) of the energy conversion involved.
Cool!

To borrow the concept of “energy slave” from Richard Heinberg in The Party is Over: If one takes the value of 1/10 hp as the amount of power that a reasonably fit human can maintain an output of over the period of a workday, then it would take the equivalent of ~720 human energy slaves (~72hp x 10 slaves/hp) to provide us with the power we have available to us in our little cars. Obviously this crude but reasonably accurate analogy of much more dramatic when applied to SUVs. We are all living like kings and queens
