how exactly do you adjust your fuel pressure? could you bring up the pressure even though you have stock injectors? also, how would you know if your running too rich or too lean or just right? thanks

 

wideband

 

adjusting the FPR is pointless unless you're tuning the car, or at least have a wideband to tell you what's going on.

 

hahaha.. well i guess imma bump this up cuz no one answered my question yet.. i know u need a hex key and maybe a 10 or 12mm wrench but which way is increasing the PSI and decreasing it and the actual procedures to adjust it

 

The adjustment method depends upon what regulator you're using. Some use a wrench and a screwdriver, others may use an allen key, etc...

 

i'd just leave it up to your tuner...unless of course you do have the knowledge to do it yourself.

 

do you even got a fuel gauge that tells you fuel pressure, if so, turn it one way and check if pressure increases or decreases, damn, how old are you, like 10? This is common sense stuff, if you can't figure that out, find someone who's mechanically inclined and have them show you or at least be there with you while you're wrenching on your car.

 

cheese i just wanned to know the right way.. and plus i been reading about u having to take out the hose on the FPR or watever.. i didnt know some people in the mainland can be such a holes.. atleast people in hawaii help out other people to make them better and not bring them down... now i know not to ask for help from all-mtr-teg cuz he goin get mad.. sorry eh brah


AND i wanned to know how you could tell if its too rich or lean? all-mtr-teg u dont have to answer that question

Yes, you must remove the vacuum hose before adjusting it.

You need a wide-band O2 sensor and gauge to do it properly.

 

what is a decent FPR to use?

is a b&m good enough? i see everyone spending 100-200$ on AEM and Aeromotive..???

 

In most cases yes, the B&M is perfectly sufficient.

 

yeah, its a stock b18c w/ bolt ons.... thanks for the advice!

 

if its stock w/ just bolt ons, no need for a FPR or bigger injectors for that matter

 

on an aem fpr loosen the nut (10mm) and turn hex key to achieve desired pressure DO NOT ADJUST PAST 43.5 psi

Why is that?

 

your ECU is calculating your pulse width based off a known number of fuel ie 43.5 psi excess fuel pressure will only result in a slight gain in fuel and can eventually overwork your injectors ever notice that your tuner sets your FP before tuning your car and then leaves it alone?
