I just picked up the parts for the electric valet switch and had an idea...I'm going to try using a hobbs switch to activate valet mode whenever my truck gets to around 40 psi. In theory, this should work. Then again, I might have problems due to the boost possibly bouncing up and down by about 8 psi from the suddenish gain and loss of fuel flow...I'll keep you posted.

 

Neat idea, but I don't think it's much of a 'valet' if the truck can get to 40psi...

edit: traditionally, the valet is there to keep others from 'rodding your ride, should they have the opportunity....

 

Yeah it wouldn't be very smooth either.

 

its also going to be set so I can manually use valet mode. making it come on at a preset pressure is more of an attempt at an overboost failsafe since I dont have a wastegate yet. But, to be honest, the experiment is mainly for fun since I just love to tinker.

 

I'd think that at 40psi the fuel pin would already be all the way down, so your switch probably wouldn't do anything. I plugged off the line to the afc the other day for a quick towing job which wouldnt work so good with the fueling i've got now. I could still hit 45 psi with the fuel pin staying at its shallowest point.

 

yeah you would have to have a way for pressure on the diaphragm side of the valve to be released or the pin would stay down.

 

unless he puts a vent that opens when the switch is activated...

 

as per the valet switch in the sticky, i have a 3 way valve meaning that when activated, it releases all the pressure in the afc while also blocking the incoming boost thus returning the cone to the thickest point and defueling

 

That could come in handy... does it do fluid also?
