    hey if you say that you have a b16 and you say that your rev limiter is 7000 then most likely your vtec isnt working because it happened to me in my b16 crx when i pinned the ecu i switched the vtec oil pressure and the selinoid make sure that you have those two pinned right in the ecu and make sure you oil pressure is grounded after i had everything right it was hitting and my rev was 82
