I added about 5-8 degrees of spark advance from 800 rpm to 4000 rpm in the lowest three rows of coast down spark (.08, .12, .16 cyl air), and blended those changes in to the row and columns around that.
Big improvement.
I see the WB go lean during decel (16.00 +) with spark from 28 to 40 depending on rpm, no Knock Retard, and just a hint of decel pop.
Now to fix the occasional stall when rolling to a stop.
