Hi,
I have to ask this question, not to make a bullshit adjustment on the fuel pressure.
According to my software spec. the fuel pressure shall be 3bar with vacuum pipe on
and 3,5bar with pipe off. The manifold pressure when the throttle is closed is appr. -0,7 to -0,8 and not -0,5bar.
So shall i adjust the pressure with vacuum pipe off or on?
