Startup enrichments are another deal..

I understand how the barometric correction works, but I am curious if I even need it. It was explained to me that the megasquirt takes an initial reading when it powers on, and subsequently uses this value to compute the change in manifold pressure from the single onboard map sensor.

So my question ...
