Hello again, as I mentioned, I bench tested the MAP Sensor with a Vacuum Pump and an Oscilloscope. It is working just as described, the nominal frequency and the measured frequency is almost identical. I am including some photos of the measurements with this link of photos. The parameters for the sensor is:

0 inHG = 159 Hz
30 inHG = 80 Hz

Also I included an Excel file with more detailed information on Vacuum Vs. Hz
and MPH Vs. Hz


Any question comments or suggestions, please let me know. I will be mounting it in my car on the next week probably.
