1981 Cadillac going in 8-6-4 mode

Still need some engine tuning, but it works. My goal by sharing this video is showing how it operates, because there are no such videos anywhere else on youtube. It’s not perfect - it’s me doing ad lib comments when I first saw this thing working. I am no trying to try to make you think this thing gets 30mpg, when the car goes downhill I say so - I understand my comments are lacking some introspection, but this is the video I chose to share because this is the first time I saw the car working in these modes. If you tell me stuff like “it`s junk“, “LS swap it!!!!11“, “Duh you get good mileage because you are going downhill“ or “you are an idiot“, your comment will be deleted.
