    These are the injector table that needs modifying. Some are more important, like others not so much.

    Depends on fixed fuel pressure vs vacuum regulated FP.


    Injector_Offset
    Injector_Offset_Adjustment*-06
    Injector_Trim_Factor*1mb
    Minimum_Injector_Off_Time

    Default_Pulse_Width
    Flow_Rate_Pump_Correction*04-
    Inj_Slope_Fuel_Flow_Mod*04-
    Injector_Slope*04-
    Short_Pulse_Adjustment
    Short_Pulse_Limit
    Use_Inj_Slope_Modifier*04-

    I think I got all of those values in from the HPtuners info given that the terms aren't the same across these platforms.
    When I get the engine back together I'll give it a shot and see how it goes.
    Feel free to use this bin if you're swapping to these injectors. I get a lot of help from these forums and it would be nice to give something useful back.

    It appears the 12613412 injectors are common for 2010 ~ 2020 applications that often used the E38 ECM.
    It’s very challenging using injector parameters from an E38 Operating System for a P59 PCM Operating System

    Yes, that is the hard part. The HPtuners thread above is where I got the converted data from. Others have used it with that software, so it’s probably legit. Just making it work in other places is the challenge.
