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.
let me check later this week when it quits snowing and i will see if my datalogger can record map voltage, i think it does. if so, i will record the screen and post up the video for you if you like.
