Sorry I have pretty much the same car (08 LX sedan MT) so I'm curious. I've always wanted to get a tank over 50....

That's OK, happy to share information. I don't have a ScanGauge, so figuring LOD (= Engine Load?) is more guestimation. But basically I tried to stay under 25% throttle when pulsing - just gentle gradual acceleration. I pulsed to about 55 mph and glided back down to about 25-35 mph. We figured we had to do that because of the time limitation. That way we could bump start the engine in 5th smoothly. Yes, turned off the engine for the glides.
Because the accelerator pedal isn't directly linked to the throttle body, but rather is interpreted by the computer, having high loads at low engine speeds actually hurts the mileage. At low load and low revs the i-VTEC kicks in and switches to lean burn mode and opens up the throttle plate for reduced pumping losses - or so the Honda documents say I've found searching the interwebs. The engine is most economical between 1500 and 3500 rpms according to those sources.
I found that the best trick when driving my car is to avoid varying the throttle pedal too much - when cruising keep the gas pedal in one position. Even if the revs climb the engine should stay in lean burn mode up until about 3500 rpm, or 80 mph, if there isn't too much cross- or headwind. This is speculation, and I unfortunately don't have the money to verify it with a ScanGauge. But so far the above information has yielded the best mileages.
What do you do to stay over 40 mpg? My driving is plagued with lots of city driving...
