However, as the motor warmed up more (about 20 minutes from start up), i was unable to get it into lean burn for more than a few seconds..... WTF is going on!? is the CA ECU screwing me?
granted, for the couple minutes that I was able to keep it in lean burn - i got VERY good *instantious* mileage, like a good 8mpg more than i would normally get during that section of my commute.

My Civic (7th gen) is also a Cali Civic and has lean burn. It took me a little while to get the hang of it, but now I can keep it in LB for nearly all of the 18 mile highway portion of my morning commute (it usually blips out for a couple seconds 2-3 times).
I watch TPS% on my ultragauge and changes in TPS must be VERY slow (less than 1% change per second) or it kicks me out of LB. Doing this, I can accelerate and get TPS up to as much as 29%, or slowly slow down.
