Default 4.7v zener diode map clamp...

For those of you running a clamped map circuit, what type of setup do you have? Is it a simple zener in place, or a adjustable...?
Im interested in what happens to the car when the map is clamped and timing goes up, as well as boost. what are your experiences?

I would want the clamp set up top, so as to having 4.95 volts or so. That way my pressure is at least known up to that point. would a potentiometer set up in a way allow adjustment in the 4.8-50v range? how would one go about this?
good night!

What "perceived" boost levels correspond to those voltages?

Default Then get a Split Signal fuel cut clamp. It is adjustable and doesn't change the voltage scale below

the clamping point like some Zeners can.
