Ignition Timing Advance Curves

Ignition Timing Advance Curves
Does anyone have or know where I can find the factory ignition timing advance curves for a 2011 FLHTK?
I'm playing with the timing curves on my bike utilizing a Power Commander V (PCV) which I can adjust up or down in one degree increments at various rpm and throttle positions, but I have no way that I'm aware of to determine what the baseline is.
Any help would be appreciated.

Yes that is what I'm trying to do, but the PCV doesn't have the capability to show the actual timing settings... Only +/- values to the factory settings.

If you have a PV maybe you could tell me what the factory settings were for your 2010. That's what I'm looking for.

Thanks Mark. But I'm looking for the actual timing advance, i.e., 10, 20 ,30 degrees etc.; not the values evident in the PCV map(s) which are simply deltas to the base timing.

typical full advance on an evo H-D is 35º, that's with full vacuum at above 4000 rpm ( remember that low vacuum, such as WOT retards timing)
not much help, I know...
When timing independently is has not been unusual to run the rear cylinder a degree or 2 retarded compared to the front cylinder--- but that would be more typical with a carb or throttle body injection.
I think that you can only ask what the max advance possible is, all the settings in between will be affected by the ECM dependent on the sensor input
Can I ask what you are doing- maybe I can learn something.
