Danny, just wanted a second opinion on my start. I've got a 4.070" bore, so based on that graph, I'm thinking it puts me about 5.66.

Also, was wondering what you thought about setting up a small 10 RPM cell in the map to bump timing for in just a little spot to calibrate. I have to drive at least an hour to find a hill, unless I use a highway overpass. Hoping to use this method on a blower motor we are building for a boat. I've used the single wires a few times, but first 2-wire attempts very soon.

No input on this idea, to create a short knock where loading is not as simple as a hill?
