sry if this is in the wrong forum, i dont know much about electronics
I got this schematic off a site that was last updated about 6 years ago, so i couldnt e-mail the author the question. its for my car, my computer on my car cuts the fuel if boost from the turbo goes beyond 11psi, the MAP sensor tells the computer how much boost the engine is taking in. So if you let the MAP sensor send its normal signal until the voltage for 11psi(around 4.7v) is reached and then make it stay at that voltage the computer wont know you are getting higher boost than 11psi(or whatever you set the clamp to). So this device i posted allows current to pass through normally until the voltage set by R3 is reached and then clamps the voltage at that point.

This voltage clamp is designed to limit the input voltage based on the voltage set by the trimmer at R3 (Vref is 5v input), and then send it to output. But it doesnt limit the input voltage until the set voltage is reached.
Sorry if thats hard to understand cause i suck at explaining things.
But my question is, i dont have a 12v on my application so i really dont need it on the voltage clamp. And i figured since it has a diode that blocks the 12v to the system anyway i could just take it off completely without affecting the performance of the device. So do you guys think it would affect anything?
And also it says "Noise suppression is achieved via the use of a low pass filter on the input, formed by R2 and C1. High frequency roll-off is at about 100 Hz, allowing the circuit to be responsive but effectively suppressing RF noise.", so does the D2 diode have to stay in the schematics for this to work still? Or can it be taken out since the 12v line and diode was taken out?
Here is what i would like to have it set up as
