Thread: How do you change injector size on a Mustnag

    How do you change injector size on a Mustnag

    I'm screwing with an 08 mustang GT, we procharged it and went with 39# injectors. But there seems to be two settings for injector size, low and high. The really confusing thing is that the low shows 29 and the high shows 23? Also when I click on this to make changes I enter in 39 for example when I click to the next box (or tab) it changes the number to 104794.21?

    Any help would be greatly appreciated.

    Can you please post your tune?
    It doesn't have to be perfect, it just needs to be done in two weeks...

    Yea, suppose that would help.

    EDIT:- Bill, it's not uploading, I'm just gonna mail it to you if you could upload it. Don't know why it's not working, it just says Wait, uploading file, but seems to freeze and just stay like that.

    Injector constants seem to change without issue for me

    I would assume changing constants is as simple as scaling them up from what the stock values were for the most part unless someone has the exact figures you are supposed to insert for specific injectors.

    use this number for the low rate = 48.24909

    use this number for the high rate = 40.29242

    use this for the breakpoint =0.00001000

    use this for the offset voltage =
    0.00493
    0.00493
    0.00237
    0.00160
    0.00137
    0.00119
    0.00104
    0.00091
    0.00081
    0.00081
    0.00081
    0.00081


    PW minimum = 0.68700

    You've got a lot more things that need changing other than the injector #'s though if your starting with a stock file....

    Ford Racing has the exact injector values published on their website HERE for all of their injectors. The good info is in the "Calibration Summary" documents at the bottom. You should be able to grab most of what you need to make them work from there.

    On a separate note, if you have interest in joining a crew in the Middle East for more comprehensive training session you may want to speak up in THIS THREAD or contact me offline.
