Default Can you drive with vtec solenoid unplugged?

Just curious. Nothing is wrong with mine at all but just curious if it was mess anything up or drive fine if I unplug the vtec solenoid and take it for a spin. Kind of interested to see what a non vtec s2000 will feel like lol.
Will it cause any issues that I am tuned with a vafc?
If there is any shot what so ever of it not being I won't but as dumb as it sounds kinda want to see what it feels like.

Yeah. Unplugged VTEC = no solenoid engagement = no higher lift cam = worse-breathing engine over 6k RPM = less air = more fuel = super rich over 6k RPM.

Therefore, no damage, no knock.

i'm pretty sure driving in limp mode wont even let you rev high enough to reach the vtec crossover point. having said that, staying out of vtec with the solenoid plugged in does the exact same thing.

you have the vafc, set the vtec crossover super high instead of messing with the solenoid. when satisfied, just reset it back to the previous settings.
