vtec-e .... maybe I don't totally get it

Ok, now I'm a bit confused. The vtec solenoid doesn't operate at the same time as leanburn? I was under the impress that the engine had to go from 16 to 12 valves to let the condition be right for the leanburn. My thinking was that if I monitor the solenoid that I would know when leanburn was happening. But is there some other sequence that I'm missing?

I can feel leanburn kicking in and out, and when I'm in second gear to slow down for a toll gate, I put on the gas and it feels like afterburners kick in at 2500 rpm or so. Are these separate processes?

In the California version, does the vtec kick in and out at 2500 rpm?
