I have a GRT 4000 EIS with a map sensor and was trying to check the calibration. I know it is supposed to read alt setting minus the field elevation.
I wanted to check it by pulling a 10 inch vacuum on the line at the cylinder head. Mine will leak down 10 inches in about 4 seconds. Is it supposed to do this?
I have emailed GRT 3 times and called 3 times and it appears only one person there knows the answer and he isn't there when I call and doesn't answer emails.
Thanks
