I have a FM map for my Road King and am pretty happy with the performance. But the decel popping is rediculous.

Should I enter negatives where the zeros are to alliviate that?

 

You could but you will have better luck using positive in the 0 tp column. Watch the rpm's and increase those cells in multiples of 5 until the pop is gone. Just confirm you have no exhaust leaks first.

 

I have mine set at +8all the way up to 3000rpm and it only just decreases the popping to a tolerable level.

 

I would only adjust the cells above 1250 RPM's, anything lower and you will be adjust the A/F at idle. Add 5 to each cell 1500 RPM and above to both cylinders, keep adding 5 untill it goes away.
