    WARNING: This is not HPT sponsored advise, it is my own opinion

    I have attached a tune that you can use to compare against your stock tune to get the injector data. It is based on TJF1 stock with ID1000 injectors. You need to rescale the Injector tables as well.

    ID1000_Adjusted.hpt

    Here is the values raw, with scaling but its not depicted here.

    Flow Rate Low = 106.84116
    Flow Rate High = 94.13718
    Breakpoint = .0000224
    PW Minimum = .27200
    Pressure Drop Ref = 39.15

    Give the values in this file a try. This is what I used in my 2013 GT500. Idle, part throttle and WOT are perfect. Just the Injector Control entries.

    The problem is, I replaced more like that. 4.0 whipple SC, monoblade TB, Aeromotive fuelpums 340... hard stuff to get this car to smooth run.

    What I have in that file is just for the ID1000 injectors. There are many other tables you will need to tune to get that engine to run right.

    You have to request it to be downloaded to your customer center via email to support with your ID number. [email protected]

    one more question
    here in the forum I got the calbration for the ID injectors 1000.
    Flow Rate Low = 106.84116
    Flow Rate High = 94.13718
    but If I check the ID website, and calculate the flow rates I got only
    Low rate = 88,30440
    High rate= 76,47840
    do I use the wrong units? or what is my mistake?

    If you look at the file I posted you will see that I have 88.30440 and 76.47840 converted to lbs/s to match Injector Dynamics chart. Those values work and run find in my car. Not sure where Matt came up with the numbers he posted.

    I think the same!
    But I'm new and not sure if I make a mistake.
    My next problem is the MAF and the throttle body adjustments. The tuning guide say use the scanner and check ETC Vacuum, IPC wheel Torque Error, ETC Effective Aerea and ETC Throttle Angle Error.
    But exact these values are not to see in my 2007 GT500. How to go further?

    For now you need SCT to log it properly.
