i'm using a s200 with the 2 stage clutch switch. i left it unplugged since i wasn't using it and also had the have the car tuned without it. i noticed that my vtec wasn't engaging and everything is hooked up properly. when i plugged in my clutch switch and try to take the car pased 5500rpm, it sounds feels like it's hitting the rev limiter at the point my vtec would engage. if i unplug the clutch switch, i can go past 5500rpm but i have no vtec. anyone have any awnsers? i also got poor results on the dyno so i think the vtec had to do with it.
