Yeah but the problem is I don't know what the voltage scale of our MAP sensor is, Like say 17psi = 3.45 volts.

And without that info tuning a clamp can either A take a really, really long time or B be dangerous.


Once I find the voltage scale out, I have a friend that makes a much better clamp then that for about the same price. It actually has a test source on it so to see the clamped voltage you just test that source. It also can work of a independant power source vice the MAP sensors power source.
