I was thinking more like the GT. One concern is the pressure sensor reading, but then again, the v twin has a MAP sensor so, not sure how intertwined the ambient pressure and MAP are.

Ok, I just learned something. Had no idea the Spyder had BOTH a MAP and BAP sensors. Never seen a EFI system that tried to use both. SD uses BAP to calculate air density along with temp. MA system uses the MAP to control fuel rail pressure. Guess this system could be doing exactly that, never looked into how the fuel pressure control works on this bike. Did not see a return style regulator so it must be PWM fuel pump control.
