So I finally decided to take the leap to SD and so far i cant even get the car started. It seems like my MAP sensor (Omni 4-bar) is always reading between 29 and 32psi. I ran the car with my gm maf to gather some data and run the SD VE adjust tool, but the suggestions I got were way out of whack as it only made adjustments in the 30 psi range of the VE table. Even with the car off and key on the map sensor is logging 29.7psi. When I unplugged the sensor while logging the readings started jumping all over the place, instead of settling.
I wired everything per ecm instructions using the gm maf cable with sd breakout points. IAT wasn't logged at the time. The map sensor is tapped into the back of the intake manifold with a short vacuum hose.
Do you guys think it's a faulty sensor or I did I do something wrong?
