Default [ED4] No rev limiter / vtec

Hello, first, sorry for my bad english, but nobody in french forum can help me ^^

I have a civic ED4 (Sedan 1.6i mpfi) with d16z6 swap from EH9 (ferio ESI)

the EH9 was my previous car, i know the motor is running perfectly before swap, i just put ECU and Distributor Harness OBD0 > OBD1, wired vtec / O2, and change map sensor for the one over throttle body.

the problem : when i floor it, there is no rev limiter "hit", like carbs, here is video from engine and tachymeter :



and some power is missing high rpm, i don't hear the vtec (no intake, i should hear it a bit, but nothing)

someone have some clues ? thanks ^^
