nope. it's a true lean burn indicator. it will stay on even above the 8v "no vtec" into the 16v 1st stage vtec with load changes. for example, going over a hill (overpass) it will sometimes "bump" into 16v mode. the motor pitch changes, the mpg's drop, the vtec opens, and I climb the "hill" better. not until I cross the ~40% mark on the throttle does the econo light go out.

this is 80mph with a vx tranny and lean burn:

same motor& ecu, LX tranny 80 mph.

those were before the "guido"... but still, well above the d15z1's lean burn window, if I'm not mistaken. Remember I run a jdm ecu - they have different rules (which I don't fully understand!)
