Thread: Holley HP EFI LS1 True Or False?

  1. #1

    Default Holley HP EFI LS1 True Or False?

    "Holley EFI tables are quite basic compared to OEM systems?"
    I'm in the process of arranging a tuner and he made the above comment. Is it in anyway true?
    There aren't any Holley experts over here, so he is probably more used to OEM.
    So I wondered if there is something he might be overlooking on the Holley.

    Yes, it's true. OEM EFI ECUs have many more fueling/ignition tables. An OEM EFI calibration has a team of engineers, over a million dollar budget, and over a year to fine tune one particular engine model to perfection.
    May God's grace bless you in the Lord Jesus Christ.
