    Default 3sge beams altezza fuel pressure


    TO REMOVE ADS, PLEASE

    So I got a 3sge beams in my ae86, I was wondering what people are running for fuel pressure? I heard of some people running 40PSI, others 60PSI. I'm not sure what to run. I'm currently putting my fuel setup together now with a walbro 255 in tank, with a return line setup back to the tank. I'm also running full vipec V44 standalone with ITBs if that makes a difference. Some input is appreciated.

    Altezza factory fuel pressure is 62PSI, I have been running this in my Beams AE86 without issue.

    I will also be running a return. So should I set mine to 40ish as well?

    If you're running aftermarket or standalone management then the precise fuel pressure you set is largely irrelevant. High enough for a good spray pattern and enough flow through the injector, low enough so you're not pressing your pump too hard. Then you tune the ECU to supply the right amount of fuel.

    So set mine up for 42 and tweak it when I get a tune

    yeah pretty much what hen said.
    i just used 40psi because that was what the startup/base tune was tuned to.
