I read this on Power Commanders web site and after making adjustments to the PCV, my popping was virtually eliminated. Hope this helps....
Q: I am happy with the way my bike runs, but it “pops” during decel. Is there an adjustment I can make that might help with this?
A: Some decel popping is unavoidable with certain exhausts, but there are things you can do to reduce or even eliminate it in most cases. The first thing we strongly recommend is replacing the exhaust gaskets. Most people tell us “mine are fine, I don’t feel a leak”, but after changing them they find that the popping is reduced. Also, check all exhaust joints for leaks. Tighten all clamps and replace any gaskets that can be replaced.
Once the above is done and you still have popping we can move on to the fuel map. Open the map you are currently using. In the 0% TP column from 2,000 RPM and higher enter a value of 20. Click upload and ride the bike. Often this is the only change that is required. You can also add a value of 10-15 in the 2% column from 3,000 RPM and higher (in addition to the 0% adjustment).
