Hi..i am plannin to buy zex kits..Do you push a button to inject nitrous into the engine or is it automatically injected for you?if automatically injects for you at wot what happen if you miss shift goin into gear does it cut the nos out so your motor wont get damage ? i am new at this zex kit..How do i chose what gear to have the nitrous injected it in. is it like the standard NOS kIt you push a button and it injects it for you?plmk.thanks

 

It's a switch. It's throttle activated. If you flip the switch, but don't step on the gas, nothing is going to happen until you step on the gas. Yeah, I wouldn't recommend missing a shift. Just ask Pinhead what happens - 10 bent valves for him
