  • Question

    Does the EFI V5 update for the terminator x as well? Or is that just for hp EFI and the Dominator?

    By Everton E. on October 25, 2020

    Answer
    Hey Everton, The "Holley EFI V1-V6" software is only for HP and Dominator ECUs. Terminator X has it's own tuning software. You can download it at this link. https://www.holley.com/support/resources/#Fuel_Injection Thanks!

  • Question

    I am new to your product and have a few initial questions: Should I start with a more basic version instead of EFI V5? I am a Mac person and understand that this is only a windows based program - is that correct? I am looking at windows laptops and wanted to know how much ramI need to run the program? (4GB or 8GB) I will be tuning a 427 N/A 2017 COPO Camaro Thank you - George

    By George H. on October 30, 2019

    Answer
    Hi, George. Great questions! All Holley EFI tuning software is Windows-based and will not work on a Mac operating system. You will need a windows based computer to use our tuning software. That being said, just 4GB of a ram is sufficient to run any version of Holley EFI software.
