    You must have done something wrong with the EFI software "Enable Static Timing Set".
    Did you enter 28° and click "Set"? (I think it's "Set"...I haven't done it in a while.)
    10° is the "Ignition Reference Angle", not necessarily the timing advance at idle.

    After changing the Inductive Delay value, click "Save" and cycle the key off-on.
    The engine must be shut off & restarted each time you change the Inductive Delay.
    Step 2 of the Timing Synchronization instructions above, is clear on this procedure.

Anyway, I was online and tried it several times to get the timing to move off 10°, but with no joy.
    I suggest completely removing the Holley EFI software from the "Control Panel", "My Documents" (Holley folder) and the
    "C:Drive" (Program Files, Holley folder) and install a fresh EFI software download. Save your Global Folder somewhere.
    Often times, when EFI software related functions don't work properly, it's caused by a corrupted software download/installation.
    Conversely, often times, when actual ECU related functions don't work properly, it's caused by a corrupted ECU firmware installation.
    Also, try completely disconnecting the battery for 20 minutes. This "resets" some unusual ECU issues.

    Software & Firmware Versions:
    Software: click "Help" tab (top toolbar) & "About Holley EFI".
    Firmware: click "Sync With ECU" & "Get ECU Info" (Key-on/USB connected).
    The latest software & firmware can be downloaded here:

    https://www.holley.com/document/tech...g_firmware.pdf (How To Update ECU Firmware)
    Before updating firmware, ensure the current Global Folder is saved somewhere, since it will be erased from the ECU.

    Latest V4 EFI Software & ECU Firmware:
    The latest Holley EFI V4 software & firmware can be downloaded HERE.
    Read the V4 Software Overview document HERE, or in the EFI software "Help" Contents.
    Be sure to successfully install the new V4 software, before installing the ECU firmware.
    Ensure the Holley EFI software is not open and the ECU is not powered on/connected when installing the new software.

    EFI Software Help Information/Instructions:
    ‒ On the top Toolbar, click "Help" & "Contents". This opens all Help topics.
    ‒ When navigating the software, click "Help ?", drag it to any parameter and click again.
    ..This automatically opens the definitions for that specific parameter.
    ‒ Tuning information can be read by clicking the F1 key, when you're viewing any screen.

    Yes, the engine & ignition components must be in proper working order, before attempting to setup or tune an aftermarket EFI system.

    Just wanted to say what a great article, rife with information!
    Just wondering if you can do this on an Avenger using the handheld tuner only vs. a laptop via USB?

    If the Avenger handheld controller allows access to the Inductive Delay parameter, then yes.

    Danny, I have a question about the "Enable Static Timing Set".
    I've set the initial idle timing, and I'm checking the high rev timing.
    The 25° or 30° that's entered, is the timing I should see on the degree wheel with the timing light?

    Engine is a '49 8BA Flathead with twin Autotrend throttle bodies.
    It's in the process of getting the engine tuning setup.

    Yes, on the crankshaft damper. Always believe the timing light above all else...it's always the real timing (if there's a discrepancy).

    In the "Set Static Timing" screen, there are "SET" "Get" & "Clear" tabs. I just installed a GM HEI computer controlled distributor, and I'm trying to set the initial. I've tried it several different ways to set it at 10°. My timing light shows that, but when I select "SET" the vehicle starts to run poorly. Even though the base timing shows 25°, the timing light is still showing 10°. I've read this thread several times, but saw no mention of the "SET" "Get" & "Clear" tabs. Thanks.

    Are you trying to set the (actual engine) idle timing to 10° or 25°?
    Is the idle timing in the Base Timing Table set to 10° or 25°?

    The 10° "Ignition Reference Angle" (GM HEI) is not the idle timing.
    Most engines won't like 10° idle timing, and it'll glow the header tubes red.

    I've read this thread several times, but saw no mention of the "SET" "Get" & "Clear" tabs.
    You'll only need to use "SET" & "CLEAR" to enable & disable the Static Timing Set.
    May God's grace bless you in the Lord Jesus Christ.

    Honestly, I was trying to set the base timing to 10°. I've been working on another vehicle with a different aftermarket ECU, and that's what I set that at. I went back & reread the first post, and I think I had confused myself. Let me make sure I have this correct in my head now:
    1. Select Enable Static Timing Set from the drop down menu.
    2. Enter the Static Timing value I want, you recommend 25-30, so that's what I'll go with.
    3. Move distributor to match the Static Timing value.
    4. Select "Set" and that's it?

    No, your step 3 & 4 are reversed.
    I think you're confusing what the "Enable Static Timing Set" function actually is. It's not permanently setting the ignition timing for you, and it's not necessarily your idle timing. It's only a temporary tool to assist you in synchronizing the ignition timing. You actually don't even have to use it, but it's much easier to adjust the Inductive Delay with it. "Set" just activates the entered timing value you chose, to temporarily lock the entire Base Timing Table at one fixed value (like a locked out advance distributor). When you exit the "Enable Static Timing Set" function (timing synchronization complete), you're back on the Base Timing Table to make timing changes/tuning.
    May God's grace bless you in the Lord Jesus Christ.

    I got it lined out, works great. Thanks for the help, it's greatly appreciated!
