Ok heres the deal i have a 02 accord had the vtec controller hooked up at a local shop. took it for a test run i had no power my engine light came on my rev limiter kicked on at 4 grand Any takers ? everything else worse i unhooked the v-tec wire. we hooked the computer up to it and it said something like v-tec sylanoid disengaged or some **** lol. any help and of course i have a obe2 ecu holla back. thanks to anyone who may help me.

 

Did you use the correct settings specified in the manual?

I was messing around with the settings when I first installed mine, and having an incorrect sensor set caused the car to stutter a bit.

 

i dont have the manual for it its a f23 engine i got it off my buddy for a steal the is just a show car but id still love for it to work. i dont know when the stock vtech engages my tranny shifts at 6 grand and the rev limiter kicked in at like 6500.

 

There's a specific start-up procedure that needs to be done.

FYI, 6th Gen I4s have variable VTEC, where the throttle position is the main factor. Altering it with a controller changes it to stable.

 

so am i wasting my time or can i get this to work and actually make a slight difference.

 

i think we may need a few more details to help u out, what engine are we working with here? is it all stock? if so, whats the vtec controller being used for?

 

is the controller hooked up right is the first question?

 

we figured it out. my motor was one of those during the transition period from rpm vtec engagment to throttle vtec engagment aka vtec then to i-vtec. The are no marking that my motor is an ivtec motor but i cannot hear the vtec engage what so ever i researched it online to and that is what i found thats its that variable vtec **** lol. owell guess it looks pretty thanks to all you guys who helped i really appriciate it.
