Default MAP signal

Hi Terry,
Where is your MAP sensor getting its pressure source.
It should be on the throttle body for the most stable pressure (not on one cylinder). Your kit was delivered with two .020" orifice adapters than can be used to dampen the pressure signal - are these installed?

You can simply switch the plugs between the two MAP sensors if you want to swap them between ECUs to see what they do,
