BEEN READING LOTS OF THREADS ON FUEL PRESSURE SETTINGS BUT STILL UNSURE ON THE BEST SETTINGS FOR MY CAR
92 WRX
CAR CURRENTLY RUNNING
SCOOBYECU
FULL 3INCH DE-CAT
STAINLESS HEADERS
FMIC
APEXI INDUCTION
LIGHTENED PULLEYS & FLYWHEEL
STANDARD INJECTORS
ALSO PLANNING ON DOING A PARRELLEL FUEL RAIL SET UP IN THE FUTURE ,
AND GOT SOME 550cc INJECTORS OR WOULD THEY BE TO MUCH FOR MY CURRENT SPEC
ANY HELP PLZ

 

550cc are to much as far as fuel pressure on standard injectors should be around 3.5 bar no more I have 440s in mine and it is set at 4bar

 

is that with vac pipe off, plugged or unplugged?
also got access to a sun gas analsyer machine could this be used to adjust the fueling by the c o readings untill i get it mapped properly ?

 

Standard fuel pressure is 3 bar without vac.

sorry to jump..what shoudl pressure be at for 740's?

 

Leave it at standard pressure until you get it remapped, when the mapper will set the fuel pressure accordingly.

ok cheers banny
