    So what I'm looking for is the dimensions of the shutter wheel in the HyperSpark distributor the window dimension and the vane dimension. This would be for a Chevy small block.
    You are waaaaay over-complicating this. There are some great videos of the HyperSpark installation out there. I think you might have the plastic phasing cap on 180° out. It will drop on like this, but it's not correct. It should fit tight/perfect when dropped on correctly. If this isn't the case, then I'm not sure what you've done and I'd suggest starting completely over. Turn the engine over to and verify #1 is TDC. Drop the HyperSpark in the hole like you would any distributor. With the rotor pointing approximately at #1. Follow the instructions.

    You guys just make it worse by repeatedly stating your instructions. The objective is for him to read the HyperSpark distributor instructions, not further enabling him not to.

    I'm using HyperSpark as intended. I just have idle timing control shut off because it's jumping from -5° to 25° to keep idle smooth. I just shut it off for now till phasing issue is resolved. I agree should be easy setup. I've tuned many Chevys and rebuilt many distributors with no issues. I have followed the video and instructions and I agree in should phase as advertised. The reason I'm asking about the shutter wheel is in my brain I feel there is something else making this timing so far off. Maybe distributor issue maybe ECU I don't no. I'm more than confident that I have the engine setup correctly at 15° BTDC.

    That's the Idle Spark control. It should be temporarily disabled (Idle ICF) to check the ignition timing synchronization with a timing light.

    Yes, that's what I disabled, Idle Spark control.

    If you clicked "Save" and cycled the ignition switch off/on, then I don't know what's wrong. There was one distributor case with a defective HyperSpark Hall-Effect sensor, so you might want to contact Holley Tech Service (LINK).

    Holley is sending another distributor. I'll update results.

    OK, here's an update on my issue. I did install a new timing chain to fix 10° slop in chain. So when I installed the new HyperSpark distributor from Holley, exactly by the instructions using the supplied tool, I had the same 44° reading. But this time I only have to rotate distributor a short amount to achieve the correct timing, so finally my HyperSpark is in sync. Now I still had to set timing in the 3.5" handheld to 6° BTDC to get a smooth idle, and when I try to accel in neutral it will pop out exhaust at about 2200 RPM. I noticed there's no timing advance coming in till 2000 RPM and then it all comes in at once. So where I am now is getting setup to watch and tune via laptop,, which is new to me and see what's going on or may send car to a tuner.
