ok so here is the low down

i had a d16z6 in my car and it started knockin so i went out and bought a d16zc vtec (japanese equivalent to d16z6).
vtec work before i changed the engine and now it doesn't want to work at all
i didn't change the in take manifolds but that shouldn't cause any problems right.
so i re-wired the ecu according to the pinout guides online and it still is throwing an engine light and vtec isn't working.

please shed some light on this problem im having.
