Then I will go with that and get a wiring diagram. I am out of town but when I get home I have another guy's tunes to look at and I can get a screenshot of my alternator output setup. No aftermarket efi will have a plug n play alternator.
Edelbrock Pro Flo 4 Plus does !

I am never going to need that much amperage but the reviews and the price make it work for my build. I still haven't found a shop that can convert the factory piece.

I'm going to drop one off on Monday. I'll give you a review . He said one day to get the part.
I still want to control one with the holley controller. This will be for another project to come, 57 Desoto adventurer.

I'd like to see the conversion when you get it done. I have one-wire alternators on every classic car. My hat's off to you and Nx Coupe for getting the original to work. That Desoto should be as cool as they come.

Ok, sorry for the delay, but as promised, here are the screenshots. You have to go into your IO and setup a PWM- and name it Alternator or something similar. Then you go into your IO setup and set up your parameters for it to function. I set mine to a specific on rpm so while cranking, the alternator is not drawing any amperage. Then go into the PWM menu and set up the table like pictured. Play with the % to get the desired voltage you are looking for. I have included both HP and Termy screenshots for you. I used to charge for this info because it took a bit of work to get this figured out and functioning, but I'll help anyone on here with this kind of stuff as I have gotten a ton of help from this board to help me.

Hey Guys,
I had the same issue with a 6.1 install using the FAST FI system that came with no provision for charging. I used the Transpo C8313 heavy duty regulator and a factory alternator connector. It looks just like the standard electronic regulator but is designed for the higher field current of the new hemi unit. The photo shows the way it is wired in my '55 pickup. I have run this setup for 5 years without an issue. I have also seen the mopar adjustable regulator used for this. I am not sure of the part number on the alternator but attached a photo if that helps.
