MSD 6530. 3 bar to 2 bar map swap question.

    I had a bad 3 bar map sensor on my 6530. It was only reading 2 psia. I replaced it with a Wells 2 bar map sensor. After reconfiguring the msd for the 2 bar map sensor, the red ambient line is at around 20 psia.

    Did I get a bad sensor or do I need to treat 20 as ambient and reprogram all my plots?

    Thanks,
    -Jesse

    It should not read 20 .

    When to changed the psi sensor to 30psia , did you save to MSD ?

    Yes, it was set correctly for the 45 psia, but somehow, the sensor and vacuum hose filled with moisture, causing my red ambient line to show 2 psia as if the sensor were unplugged. :huh:
    I was in a pinch so I picked up a 2 bar for a Buick GN.
