. . . I asked if the pilot were the same size, are they? . . .
I need to get back out and measure that to know. Stay tuned.

It seems odd that It is the same as the small six cannot see that would happen.Measure from the bottom of the hold down flange to the bottom of the gear.
I believe it should be 2.510" to 2.515".
Correct me if I'm wrong.
If you look at the shutters, there should be one vane that is narrow compared to the other five. . . .
I'm not surprised.The Holley has that same arrangement - one vane is more narrow. I'll get some more photos and measurements tomorrow.
There are only three connections.Is there any need to add a diode when customizing the EEC-IV distributor for use outside of stock electrical configuration?
What is the measurement from the bottom of the gear and bottom of the flange?On the Ford big six distributor, I measured the center of the gear from the base of the distributor at 2.4 inches.
It was a question if one might be needed, since the distributor is getting it's voltage supply outside of the typical ECU; which would filter out any stray or non-biased voltage pattern. Adding a diode could even prevent ruining the control module if the ones in the alternator were to failThere are only three connections.
Power from the ignition switch, signal and ground.
Where would you place the diode?
The 4.9 distributor worked just fine on 12 volts using the module as seen in post #29.Most all hall effects work on 5v and sensor ground supplied from the ECM. Using it through the TFI module may cause a problem on 5v, but I'd wager it'd still work. It'd be easy enough to check. To simplify things further, utilize the latest model 4.9L distributor with hall effect and pigtail only and no TFI module attached.
The Holley port injected EFI systems do support PIP ID for #1 cylinder for sequential injection and distributorless ignitionI'm interested in knowing if Holley is actually using the #1 vane for cyl ID. I didn't think they were supporting signature PIP and I'd guess they are only using the equally spaced trailing edge for trigger. I'd also guess they built it as such so they can market the distributor as a drop in replacement as well as working with their products.
I am reading this as, the module serving as a passive interface. It will have no duty as an ignition control module anymore?The 4.9 distributor worked just fine on 12 volts using the module as seen in post #29.
I would keep the module in place as a buffer between the Hall Effect unit and outside electrics.
Yes it will be a passive interface and the Sniper 1100 takes on the ignition timing duty.I am reading this as, the module serving as a passive interface. It will have no duty as an ignition control module anymore?
