Im building a mild poor mans itr setup on a b18c1 block

I have rc310cc injectors and hondata S200

Do I need something like the B&M Fuel pressure reg. and gauge?

 

I am running one because of the increased compression and smaller injectors (stock). If you are running 310's you dont need one IMO.

 

that is kinda what I was thinking, I saw austin is just running prelude 290 injectors tuned with hondata stage 2

anyone esle feel this way too?

 

yes, you should get one even if it is a cheap B&M if you want full tuning potential.

 

what tuning will I be able to do with the fpr that I cant do with a hondata?

 

good to have.. i used to burn oil all the time.. once lowered fuel pressure + larger injectors - haven't seen any loss of oil.

thats if you can lower the fuel pressure, you have to keep it high enough not to overload injectors duty cycle...

and overall, its just easier for tuning - not needed - but good to have

 

im a lil confused on how it could effect oil burning.

ne1 else?

 

im in the same tuning boat, what fpr would you advise to get if tuning with hondata 2b and 440's?

 

hondata can't regulate fuel pressure. The fuel pressure is directly related to injector duty cycle as stated above. Both are important in tuning.

 

u dont need it. my car runs great w/o it i used to have one, didn't need it anymore

aem works for me with b&m fuel gauge

 

There is no need since he will have a Hondata...which gives him full control over the injector opening and closing(pulsewidth)...much safer to adjust the injector pulsewidth than increasing the pressure of the system, which could lead to blown seals and a burnt out fuel pump.

It is good to have a guage so that you know where your pressure is at, and it helps to diagnose a faulty regulator.

The stock FPR should work for you...you simply want a regulator that can increase pressure on a 1:1 rate.

Austin

 

You're right Hondata can't adjust the fuel pressure, but they can adjust the pulsewidth or duty cycle as you have named it, which is a much more precise way to control the fuel flow into your sylinders, and which is why a FPR is not needed for his system.

i'd say lower fuel temps.

- wanted to update - i'm still burning oil, - was driving my car much harder few times - high revs for longer times, (oil change 2300 miles ago) - had to ad 350ml of oil.

It makes sence to me too now, larger injectors improved things, but if driven hard enough, i'd still loose some oil.
