anyone know the stock PSI of the fuel pressure regulator of the B16a1 and B16a2 ?

 

google is ur best friend

 

i did that but didnt found a good answer

 

36-37PSI for and OBD-0 B16

 

thanks a lot :D

and for obd1 b16a2 do you know ?

 

pressure for OBD1 is same as for OBD0 - 35-38 with the vacuum hose at the fuel pressure regulator connected - also check it with the engine idling and the vacuum hose disconnected - with hose disconnected it should be 41-47

 

I think isnt the same.

I havê a CRX b16a1 and i upgrade my pw0 obd0 to obd1 using p30 basemap I had to increase 20% of the fuel to get a 14.0 AFR . I'm using obd0 FPR

 

found this...

dont know if is right

obd0
bar: 2,4 - 2,79 ||| psi: 34 - 40
bar: 1,75 - 2,14 ||| psi: 25 - 31

obd1
bar: 2,8 - 3,3 ||| psi: 40 - 47
bar: 2,15 - 2,65 ||| psi: 31 - 38

 

from the workshop manual, an OBD-0 B16 should have 35-41 PSI at idle with the vacuum line to the pressure regulator disconnected.

 

38 worked good for me.
