when you select the fuel pressure switch type thing is the reading when the hose is disconnected or connected? thx

 

I put mine at 42psi hose on. Dont really know the answer but i dont think its that crucial as long as the ratios are good on the wideband.

 

The fuel pressure setting doesn't matter i Uberdata or Hondata. All it does is adjust the entire fuel cells, which is like selecting them all and adding xx% fuel. Hell I could pu them at 100PSI fuel pressure and then just subtract the fuel out of all the columns . Don't worry about that setting, sdjust it according to your wideband A/F meter

 

k thanx
