...The only way to make DDFI3 work on the older bikes is to swap in an 08-10 motor, wiring harness, and ECM...

You could change the connector. Just throwing out an option, not like anyone is actually going to go through all this work unless going to Eric's level

DDFI-3 ECM has a reserved pin for cam position sensor input (Gray[3]]).
The live data parameter Din[0] reflects the CMP state.
