A question was posted in regards to the fitment of the PC III on the different years/models of bikes and this is what it comes down to.
Basically the 01-06 except for the dyna line would be the same unit, different maps and install.
The 06 Dyna line takes a different number because of the 02 sensors, and the touring in 07 and softails use the same unit, different mapping and install.
The 08 is where it differs and that's because of the FBW throttles where the softail line would use the same unit as the 06 and prior softails.
