Alright, well my Ls/vtec is running great! but vtec wont engage. I have it just wired to a switch like a lot of people do in hybrids. When i have the car off and i hit the switch i can hear the vtec solenoid click. Then when i start the car and hold the rpm's at like 5000 and hit the switch there is no difference in sound or power when i'm driving. It simply isn't pulling. now, i tried another vtec solenoid that worked when on a previous car and the same thing. Where should i start? I have the stock Ls oil pump but i don't think that should matter should it?? I would think that the Ls oil pump would give enough pressure especially since it's hooked up to a switch and not reliant upon the pressure! Any ideas and info would be great!
thanks guys

 

vtec will not engage onless you are over some 10 MPH and temp. is over 60DG

 

okay well... even when i drive it doesn't sound like it's changing at all and plus, i have it powered directly from the battery to a switch to vtec solenoid so it really shouldn't matter. I don't know what the hell to do. i'm beginning to think that i got some really shitty automatic cams and vtec is just really weaK!! who knows?

 

does your speedometer work?

 

run it back through the ECU just like stock.
THEN tell us if it works or not.

 

yes my speedo works. I'm running a non vtec chipped si ecu so i can't run it through the ecu.

 

then buy a ECU for VTEC !!!??
