Were there any changes made to the engines from 2009 to 2010 on the Road King?

I have been fighting with Vance and Hines on the FuelPak settings and the same map on a 2010 is completely different than that for my 2009. All the same entries, just a different model year.

I did not think they changed anything on the engines for 2010?

Thanks

 

Possibly because of the CAT ?

 

The reason i mentioned the CAT is because if i am not mistaken the MoCo actually was able to richen up the fuel a little bit with the CAT and still was able to meet the crazy EPA mandates. Having done this, i should thing there would be some new adjustments needed to a fuel pak etc.

 

I believe they changed something in the ECU. At least that is what Fuel Moto said. Also said I would not be happy trying to run an '09 map on my '10 because of this.

 

Not the engine itself but the fuel management, namely the use of heated O2 sensors on the 10.
