hi i installed my vafc2 today and noticed that when i hit vtec and it got up there in RPM's it ididnt pul much anymore... so i displayed vtec in and out and noticed only vtec out is hitting not vtec in....? my vtec is set at 4900-5200.. any idea? please elt me know, also cant post much cuz this 5 post thing.. so if u want to talk with me about it IM me limegreencivic97, thanks

 

did u cut the Vtec wire that runs to the ECU. u need to cut that wire, the connect the "Vtec in" wire to the vtec wire that u just cut. connect the "Vtec in" wire to the wire thats still connected to the ECU. then the "Vtec out" wire of the VAFC goes to the the other side of the wire that u just cut.

it seems that u have a problem with the wiring. make sure u didnt switch the Vtec in and out wires
