Thread: 2-Step question using Terminator as fuel only.

  1. #1

    Default 2-Step question using Terminator as fuel only.

    Let me start by apologizing, but this is new to me.
    I'm going to be installing the Terminator and initially I'll be using it for fuel only (replacing a carburetor). Maybe later I'll add spark to the equation.

    My question is regarding the 2-Step. I'll be controlling 2-Step RPM with my ignition box as I've always done with the carburetor. However, I'll need to shut off closed loop while on the 2-Step.

    I've read that the Holley EFI defaults to open loop when +12V is applied to the Rev Limiter #1 pin, is that all I'll need to do? Or will I need to configure something else in the software?

    All I want the EFI to do is go into open loop while I'm on the 2 step, I understand the fuel table needs to be accurate in that area.

    Thank you in advance, looking forward to sharing my findings here. I'll be campaigning this in the ultra competitive 10.00 index class.

    Yes, Holley EFI is in Open Loop whenever you're on a Rev Limiter.

    Correct, no further EFI software setup is required.
    May God's grace bless you in the Lord Jesus Christ.
