    Scaling the IAT Multiplier doesn't seem to work for injector this size.
    The only way that works for me was scaling both the IFR @ 54% and making up the rest with the Stoich,
    I guess the hard limit for injector size must take into account the IAT Multiplier that's all I can think of why its not working.

    i've found the iat modifier works invertly.

    if you want to pull fuel out you go above 1, not below.

    That's what I did but it didn't work,
    I was using 1.84 as per the difference calculated from the g/s rate used in the FPR to the actual rate.

    so If I'm running 60lb/hr injectors in my 2007 Holden ( IFR maxs at 7.9999g/s ) then I could halve the IFR table provided by the manufacturer and enter it in B4001 thus keeping it under the 7.999 maximum then change the B1213 values to "0.5" to double the fuel volume thus giving me the correct fuel pulse overall.?? And everything else stays the same like fuel pulse adder, flow correction etc etc

    The IAT multiplier won't work for going over the 8g/s limit. Might as well just flash (or maybe pcm swap) a newer 2011 up cal. But you would have to find your clutch pedal type parameters to make it work....
