'70 Dart 392 Project; what direction?

That would be incredibly frustrating!

I had about 20 mins in the shop today and I put a 12V jumper wire to my alternator and bingo, I’ve got AFR and no cutout on my gauges!

Also in my ignition setup screen I changed my cam input to poll on tooth #10 AND changed startup to wait for cam input and now I don’t have a cam sync fault! Progress.
Car also was able to idle on its own after giving it a little fuel after initial startup. Looking forward to digging into idle more tomorrow.

I saw on a YouTube video yesterday that unless you run legit ethanol free gasoline that stoichiometric is actually 14:1 not 14.7:1. I’m going to keep that in mind as I tune. Will keep everyone posted.

Glad you are making some progress. There's always that "Ah-Ha" moment when things start to work.

You know, the thought of adjusting stoich for modern fuel with ethanol in it never crossed my mind. The problem is you'll never know what ethanol content you have unless you use a flex fuel sensor. I considered adding one just so I can run E85, but the closest gas station to me that offers it is about 30 miles away, and more importantly, I'm out of analog inputs on my MS3X. I'd have to add a micosquirt or one of the digital displays that have extra inputs. I'm not looking to spend thousands just to have flex fuel that isn't even convenient to get.
This being said, I really don't run mine at 14.7 anywhere except for cruising RPM. My idle is usually around 14.2-14.5.
