Anyone know if there's any significant difference between the SERTs with different parts numbers? Will 32107-01B work on an 02 Road King as well as the 32107-01D? Is it simply that a new version is released each year to accomodate the newest cycles? Or are new maps released?

 

The current part # in the Screamin' Eagle Catalog is 32107-01D but I'm sure the 01B will work since the only new one they have come out with is the 32127-03 for 97-01 models.

 

The only problem with B would be the version of the software. I am guessing it is 4.10 or 4.12 in either case it does not have the fuel pump or the decell tables in it. I do not recall the 06 models being with the B version either. Its simple enough to rectify just have the local dealer with the dyno give you a copy of the software or call Customer Service and for 20 bucks they will send you the latest greatest. Bullchit in my opinion, but another way to get it.
