lean burn and vtec, they are independant. Don't get stuck thinking they are connected.
You can lean burn even after the change over if the load is low enough.
To clarify:
Lean burn = any time it is low load (assuming gear or temp is within spec).
Vtec (full 16v) = anytime over 2500rpm in US spec d15z1's
Notice from the above, there are 4 possible combinations, since the requirements for each are different.
