Lmao, those were good...

It improves the efficiency of the engine by changing the camshaft profile. You can read about it here:

I read it but my "vtech" drives and feels like any other 4 cyl car. How do i know if my vtec is working?

You can hear it activate if you listen to the engine. Your VTEC switchover is at 4500rpm so when you get close to that listen for a change in the engine pitch. I don't have VTEC in my 01 but I could feel it a little in my old Accord and more in my dads Prelude.

I'm thinking you won't feel much with the D17.

I could have a faulty vtec....no 4500rpm nor 3200 "feel".

if you have a 7thgen, you're not really gonna feel it, if you do at all.

I feel it.
When I start to fall asleep, I know my VTEC kicked in.

Why?
My 7th gen chair starts rocking me to sleep.
