Fueling, If the map reference is used in the fueling calcs a sin wave map signal will create a sin wave fuel output.
Yeah, this all confirms what my buddy saw with his sprintex kit months ago, swapped back to stock maps sensor and it cleared up. I assume it is only any issue at "full" boost when the pressure wave starts pulsing, since the oem sensor only reads .3 bar so it caps out and does not oscilate with the manifold pressure.
