    What is the difference between VTEC kicking in, and VTEC crossover? I have seen some ECU programs that have VTEC kick in at 5000 rpm and VTEC crossover at a different rpm.....??? I dont get it.

    :huh: ?????????

    its 2 different ways of saying the same thing "VTEC engagement point"

    VTEC is like an "on / off" switch... your either on the low lobes or on the high lobes

    what about for the RPM at which it disengages? It isn't always the same point...

    if you have a VTEC controller of some sort, some allow you to set VTEC to engage at say 5600rpms and not disengage untill you drop to say 4800rpms... that is possible and can be useful depending on the application
