EFI and elevation changes
This is probably a stupid question, but I am planning a trip to the Rockies and one of my buddies keeps telling me that I will have issues with my engine pingingsince my tune was done at (roughly) sea level. I have a PC III, and always thought the PC III adjusted the amount of fuel depending on the air density sothe air fuel mixture was constant regardless of elevation.Am I wrong? Help me out guys!

RE: EFI and elevation changes
Its the change in elevation that makes they difference, not high elevation in and of itself. Generally when you go up in elevation you run richer....less air, same amount of fuel means richer running. Its harder on a bike tuned for high elevation going to low than the other way around. EFI does a pretty good job of adjusting, so it isn't near the problem as with a carbed bike. I live at 6,200 feet, but frequently travel to MN and ND with elevations at or near sea level....my older carbed bikes would run real hot, but dang, I sure would get good gas milage on those trips. For the duration of a trip you aren't going to hurt anything....you will loose power at high elevation, may just have to run higher rpm before shifting, but again shouldn't hurt anything.

RE: EFI and elevation changes
I live at 500 ft and my dealer is at sea level (where they tuned my bikes). Current bike is new and have not been able to get into the mountains yet (way too much snow) but my previous bike was a Dyna and had a PCIII on it. I regularly went from sea level to about 6000 feet fairly regularly and had no problems. Your bike will do fine on your ride.
