I’m confused. I installed a 2009 head pipe and the Power Commander V on my 2011 Road glide Ultra. I did this to reduce the heat from the front cylinder exhaust pipe (and my foot). Using a map that was recommended by Power Commander, I have some reduction in exhaust temperature but not enough. After talking to several people I’m confused. I’ve been told the high heat is caused by a rich mixture and others have said it’s too lean. What is it? I can adjust the map if needed, but I need to know rich or lean. I have the factory air cleaner, 2-1-2 head pipe (no cat) and performance mufflers on a 103” motor.
So what say you? Does the factory dump a lot of fuel in the front cylinder to help burn off the emissions, or have they cut the fuel down on that front cylinder?
Any advice will be appreciated

Typically they lean it out at stock to meet emissions. Enriching it will help cool it to a point.

I don't know what the AFR should be on these air cooled twins. Maybe someone else can help with that.

Why the 2009 headpipe? Is it Cat-Free? Are the O2 sensor holes in the same place as the 2011 headpipe? Being in a different position will change how they communicate with the ECM.

Too hot means too lean. Enriching the mixture can make it run cooler to a point. Those Cats generate a lot of heat but so does a lean-running bike. Can you check your oil temperature? I saw mine up to 270 F before tuning it using the SEPRT, now it rarely gets above 245F on a hot day.

Not sure how to program the PCV. Can you change a block of the map for rpm/throttle position? Lower the AFR (thus enriching the mixture) a couple of points, it's typically 14.5 when too lean. Try bringing it down to 14.0 and see what happens. Don't forget to save the old program before changing anything.

High heat is caused by a lean mixture. You need more fuel. Talk to Fuel Moto and get a map from them. They have hundreds of custom maps that are made on a Dyno and will run much better than a canned dyno jet map.

Rich or lean

The 2009 head pipe has no catalytic converter and the bungs are near the cylinder head. The Power commander V allows me to run without 02 sensors. So the conscience is, add a little fuel to the existing map. More so at the RPM range I use and lower throttle positions. Will a fuel moto map work with my Power commander? I may have to purchase a Power commander auto tune sooner than I had planned on.
Thanks

Got my PCV from fuel moto custom mapped for my mods. I was told that they only do maps for the units they sell

Fuel Moto (jamie) are probably the largest and most knowledgeable shop on Dynojet products, Power Commander, Power Vision in the US. If you buy from them they double the warranty and provide lifetime tech support their data base of MAPs is much larger that Dynojet and jamie will adjust and email you what you need.

They are a good group of people to deal with

Plug color

Just a thought... Although it won't validate your fuel map across the entire RPM range a simple check of spark plug color will give you a general feeling if you're running rich or lean. Color changes go from white (very lean) to tan to brown to black (very rich). My experience with power commanders on bikes indicates the plugs typically change from white (lean, low emission factory tune) to light brown when an optimum map is made or installed. Be sure to check the plugs after running the bike in the mid to higher RPM ranges to get a more general picture of the tune.

Honestly, without some type of a/f measuring device your taking a shot in the dark. Try to find a tuner in your area that is familiar with your PC-V or spring for the auto-tune module.
