    need help converting raw injector data to NGC3 format

    i'm trying to improve idle, and don't want to just scale the injector

    attached is the raw deachworks 1000cc injector data @43psi and on the right the data DW provided at 58psi.. .

    notice the colors because the pulsewidth doesn't line up..

    how can i take raw data points (grams and ms) and convert it for use in the NGC3

    here is how i think it works..
    ecm knows engine volume & VE & RPM & density... grams of air, knows requested AFR so it can calculate grams of fuel needed

    actual injector pulse width is sum of, offset pulse width (function of battery voltage), and pw from table fuel mass PW (look up fuel mass to determine) ..
