• New Features:
Tuning Mode 4.6.2. adds new calibrations for 2007 HDI vehicles and Active Intake and Exhaust functions for HDI vehicles that support this feature. All
2007 model year ‘Big Twin’ calibrations have been updated to allow using the ‘Automatic Compression Release’ (ACR) function. Refer to the pull
down HELP in Tuning Mode for further information."
As you can see, HD has changed maps 78,79 and 88. If you run either of these maps without any "custom" changes, you should load the "new" map to take advantage of the factories updates.
If you are getting your bike tuned at a dealer, they most likely do not even use "your" CD. They will have the latest CD loaded into their computer.
