    Idiots Guide to Injector Flowrate Changing

    Hello all,

    After updating to release 1.5, I took a look at the injector scaling. It seems to be a tool that compensates fuel line pressue, with flow @ rated pressue. I have Lucas 42.5lb/hr injectors that replaced the stock 36lb/hr injectors.

    My changed table looks like this:
    VAC 0 10 20 30 40 50 60 70 80 90 100
    lb/hr 42.5 42.91 43.43 44.16 44.31 44.39 44.44 44.5 44.54 44.68 44.8
    And my stock table looks like this:
    VAC 0 10 20 30 40 50 60 70 80 90 100
    lb/hr 36.10 36.51 37.03 37.76 37.91 37.99 38.04 38.1 38.14 38.28 38.4


    Was I correct to add 6.4lb/hr (42.5lb/hr - 36.10lb/hr) to the table?
    I am using the standard, 43.8psi for rating, and 43.8psi for my current fuel pressure.

    That would be incorrect...

    you want the ratio not the difference..

    then multiply the whole table by the ratio..

    {existing table] * (new flow/old flow)

    or something like that.. that how i would approch it to start.. then tweek from there..
