    ok got some time and dug up my accel inj table and it says the 30# injector actually flows 27.9@2.7bar or 39.2psi and 29.4@3.0bar or 43.5psi .

    i'm still not sure i belive the set of accel voltage offsets i'm using atm in that bin and i do have another set of offsets that claim to be good for ALL accel injectors up to 75lb/hr. they are:
    Volts Dc uSec added
    0.00 701.91
    1.6 701.91
    3.2 7782.09
    4.8 7782.09
    6.4 4455.63
    8.0 2044.71
    9.6 1464.86
    11.2 1068.13
    12.8 793.47
    14.4 579.84
    16.0 396.73
    17.6 244.14
    19.2 91.55
    20.8 0.00
    22.4 0.00
    24.0 0.00

    ones im using atm are:
    25.6 0.00
    24.0 0.00
    22.4 0.00
    20.8 0.00
    19.2 0.00
    17.6 0.00
    16.0 0.00
    14.4 0.00
    12.8 0.00
    11.2 0.00
    9.6 732.43
    8.0 1495.38
    6.4 2807.66
    4.8 4364.07
    3.2 5981.53
    1.6 732.43
    0.0 701.91
    these are the ones i saw posted here and a few other places as well but they just dont look belivable, what do you guys think? i'm wanting to go with the 1st set of offsets i listed as there more belivable to correct offsets of similer injectors.. just cant belive all the zeros in that second set, just seems odd.

    so Zed, whats your fp running?

    I am at 44 psi so that's pretty close to 43.5.

    thought you said 44 koeo? it should drop 3-10 when running but only you can tell me how much?

    Well when running I think it is going to about 38 but I'll need to double check, but when they recommend 33.5psi isn't that with the key on engine off? I believe soo???

    i would guess the opposit as koeo is kinda irrelevant to the injectors... only thing there concerned with i would think is running fp... someone can correct me here if im wrong but it just seems most logical.

    hmmm a quick search brings it up as both ways depending on fuel system type. lol figures.

    tbh its not a ton of differance in flow either way and we need more fuel i know so lets go with 43.5psi running, you will gain a lil better attomization if nothing else. and i know from looking at all your diff logs that you definatly will need more fuel at mid and wot anyhow as well... the miniram loves fuel at tip in and under throttle.

    after some figures that may be more then we need but idk as idk how far into lean we are, only that its max that ecm can display..
    at this point richer is safer then lean and we can easily adjust the fp

    on second thought lets just leave it where it is i guess i will adjust fuel tables instesd i guess.

    here is just a baby steps bin i only changed the inj constants to what accel rates the flow at as well as i decided to change the inj offset to voltage table to the other one i had as i belive it is more realistic and is alot more somiler to the one used for the ford red top 30# injectors..

    anyhow same thing with the log as before , probably doesnt need to be as long though maybe 1/2 as long as i just need to see where that lil bit moved us.

    fish and scents arent what i think of first when hearing smelt, i think molten metal "smelting furnace"

    All this smelt talk and we will be up to 35 pages again real soon hahahahahaha. This is what this forum is all about, having some fun and learning. Great to be here.
