ECMs
I couldn't pull up a '10 103 on Harley's website, but the '11's have 9.6:1 static compression. Closing the intake valve at 19 degrees abdc gives you a cylinder pressure of almost 197 psi cold. The map you have loaded has a total advance of 35 degrees. Go into your Thunder-max program download your map from the ecm. On the selections on the left click on ignition timing maps, then timing vs. engine speed. You then need to modify your map in the 2500-3000 rpm ranges, probably take out 2 degrees timing to start. You could probably take out 2 degrees all the way through and not hurt anything. This cam is like having 10.5:1 compression with a normal cam.
