Alright well I did a search and it seems that everyone ask why VTEC isn't working.

So my question is how to tell if it is working and what is the best way??

After rewiring my car, Im not throwing any CEL codes but just wanted to make extra sure that it is kicking in properly.

I know that if I rev to about 5500 RPM on the B18C the engine should howl but what else?

you can hear it. rpms roll faster after it engages

yeah you should be able to hear the vtec......at first it will be like "wrrrrrrr"....then when vtec kicks in it sounds like "waaaaaaaaa"......will atleast that's what a b18c5 sounded like when i took my friends type-r for a spin!

also you can always wire up a diode to the solenoid, "vtec indicator", i'm sure you can find a how-to on it.....that way you can see if you are getting the voltage needed to activate vtec....

on my 99 si you can here it kick in at 5500 rpm's, it wont turn on until the engine is at normal operating temp

i love the sound and feeling of VTEC engaging! i think that's everybodies sweet spot. you know it when you hear and feel the whole freaking car pull the f#ck forward like theres no tomrrow!

if your ecu isnt throwing any codes than your vtec should be working....if vtec isnt wired up right it will throw codes

jack up your car.... start it up... put it in gear... then "drive" it... front wheels in the air spinning and rev that bitch out to 4500 (or whenever your VTEC activation is set) while one person is doing this the other person should be holding a test light to the hot wire of the VTEC silenoid... if you are getting power to it then run another test to make sure the silenoid is actually working... one way to do this is to run a power source directly to the silenoid and listen for a "click" (this test you administer with the engine off) easy way is your battery... run a wire from the positive terminal straight to the silenoid good luck

Thats like revving an unloaded engine. Thats not exactly good....

I can always hear it and feel it when I drive my bro's GSR.

or connect a simple light to the VTEC solenoid . Similiar setup to installing a vtec light in your dash . If VTEC is working it will light up . I'm not suggesting installing a vtec light in your dash . Just saying wire something up as a quick tester .

unbolt your header from the cat, and push the exhaust out of the way, then go for a drive.

Or take off your airbox and go drive around. You can tell.

just to let u know....
the VTEC engages at 4400... on the GSR....
and the dual butterflies is what u hear at 5700....
dont mistake the two.....
