We are having a January thaw which gave me the chance to try the first option to fix my backfire and stalling issue on the coyote. The Dakota digital gauge controller has a VSS output and I connected that to the Ford pcm VSS input wire. Time for a test drive.
No improvement. Bummer. The next option would be either getting the Ford speed dial (no longer available) or an alternative like this...

There's one speed dial on ebay but he's asking double the regular price for it.
Oh and I did more seam filling and sanding on the body. Need to see if my epoxy primer is still usable.
Video driving down the gravel road, straight out the headers, bit of a coolant leak, fun drive.
