Edelbrock Pro Flo 4 EFI

So I opened the unit up and it appears to be a hall effect, not the one that used light inside, also there is no provision for advance, I guess it is all controlled in the software..
It is not as nice as my MSD full billet piece, but it should work..

Just make sure when you install it you use the addendum from the Eddy tech site. https://misc.edelbrock.com/forum/PF4-Distributor-Install.pdf. After months of dealing with timing issues I just found this and finally dont feel like throwing the system in the trash. The reason this is so important is because all advance is set by the software. The instructions included in the kit discount the collective knowledge on how to install a distributor so the adendum clears it up. When I initially installed mine I set the crank at 12degress and stabbed the distro to where it was roughly 12 degrees BTDC. The problem with doing that was that the software is using 12BTDC at the crank as a reference point for the short tooth in the hall sensor not base timing. Essentially I was one tooth off so even thought the crank is at 12BTDC the rotor needs to be on the #1 on the distro. In order to accomplish this I had to turn the oil pump gear 1 tooth clockwise and boom it runs like a dream now.
