Fuel pressure regulator
Just wondering when i do the intake,maf,tb,cam would my car be fine on the factory fuel pressure setting or would it need more fuel.

RE: Fuel pressure regulator
from what i could gather it seems the computer automaticaly adjusts the fuel pressure anyways no matter what you have it set at.
therefore it seems like a waste of money. however, i never saw that proven. some said the computer does it others did not. |
RE: Fuel pressure regulator
Never heard of that,but i don't really think i will need it just wanted to see what others thought.

RE: Fuel pressure regulator
it would be better to get a adjustable fuel pressure regulater & fuel pressure gauge. you can get by with out it , but it is better to have it in case you need to set the pressure you can. good luck.

RE: Fuel pressure regulator
are you able to explain this? how does a computer control something that isnt linked to the fuel setup?

RE: Fuel pressure regulator
i guess with quik thats not right and if you go ahead and get the AFPR now it will be easier to install since you will have the intake already off the car

RE: Fuel pressure regulator
are you putting 24lbs injectors in? if you are i would get fuel reg.

RE: Fuel pressure regulator
raising the fuel pressure wont change the a/f ratio. the computer controls the ratio with the injector pulse, the regulator just keeps fuel in the rail so its there when needed. an afpr is handy when the injector size is too big or the computer tune is off. otherwise it isnt needed. the tune in the computer handles all a/f ratio duties, and the regulator makes sure there is adequate fuel at the injector to make the pulse.

RE: Fuel pressure regulator
Right!
And the AFPR is really only needed when adjusting WOT or A/F ratio, but that's not even always true neither. The computer can compensate like +-25% either way, any adjustments needed past that an AFPR is needed. |
