pc111 on 2006 dyna superglide
I have a 2006 Dyna Superglide. I got a pc111 from Fuelmoto in 2008. I have always ran the custom map that came with the unit. I want to tinker with it to see if I can better my gas mileage. I have the Screaming Eagle Air Cleaner and Screaming Eagle pipes. I have the S.E.11 racing pipes before they were taken off the market. Any of you fellow riders have any maps for my set up or have any tips or advice for me. I would really appreciate it. Thanks for taking time to read this.

Hey John, IMO I would give Jamie a call first and tell him your concerns, and see
if he has any ideas on improving you mileage, he may be able to send you a new
map, or have some ideas, just a thought

Here's a note on the Power Commander website related to fuel economy:
All Models
My Power Commander came with O2 eliminators, should I use these and what are they?
On bikes that use an O2 sensor in the stock exhaust have a closed loop area that can not be adjusted by the Power Commander alone. If you make adjustments with the PCIII in the closed loop area the O2 sensor will sense these changes and the ECM will alter the fuel curve accordingly. If you want to have full fuel control over the entire RPM range of your bike then you will need to bypass the closed loop area which the O2 eliminators will accomplish. If you are looking for the best fuel economy and not worried about making changed to the closed loop area you can leave the stock O2 sensors connected and still make changes outside of the closed loop area with the Power Commander.

I don't really understand a lot of the technical stuff like closed loop and O2sensors. Thats one reason I have never changed my map. My pc111 did come with two covers for an O2 sensor. I folloed the instructions and unplugged them and put the covers on. One was on fron pipe by voltage regulator and one was under the seat. Should I take covers off and plug them back in ? Sorry if I am asking a dumb question, but I really do not know

Not a dumb question at all and I'm certainly no expert myself. But here's what I believe it means, and hopefully someone can come along to correct me if I'm wrong.
The term "closed loop mode" refers to the throttle position and engine speed (RPM) combination where the ECM makes Air/Fuel calibration changes based on information received from the O2 sensors. It's typically a lean condition in this area of the map (i.e., less fuel), which means fuel mileage should increase, but engine temps may increase. To have the ECM behave in this manner again, you can take the plugs off of your O2 sensors and plug the O2 sensors back in to their respective wires so the ECM can once again begin to calibrate in this area. You would leave your PCIII installed as it currently is and make no changes to the map -- simply plug the O2 sensors back in where they were originally.
Outside of the closed loop area (i.e., increased throttle position and higher RPM range), the PCIII will be able to make adjustments for fuel where the ECM will not interfere with these adjustments. These will usually be those areas in the fuel curve where you're on the throttle hard and/or at higher RPM ranges.

You should not connect the O2 sensors back. The plug for the wiring harness contained a resistor that bypasses the closed loop system. This closed loop system work within a very narrow range, mostly to keep your system but allowing for a slight change in fuel mixture.
The PCIII has various maps that allow you to run a richer fuel mixture that suits your bike. Due to various tolerances in sensors each bike is different.
I have a 06 Dyna, Stage One, AC, Screaming Eagle II with Big City Thunder baffles, and running all Amsoil. I ran some different maps from the PCIII site, and even a custom map another forum member sent. I kept having decel popping or bad gas mileage. Finally, I took my bike to someone that had good dyno tuning skills. Cost me $300, but the best $300 I've spent. A good dyno tuner can tune both cylinders independently doing an accurate measurement of the Air/Fuel Ration which is important. Too lean and you can fry a piston. Too rich and you got black smoke and fouled plugs.
One thing I learned was that he prefers the stock plugs and removed my SE plugs. Says he has better results with stock plugs and that the color range is much improved.
I understand wanting to save a few $$, but you really should consider doing a dyno tune. I've been well pleased.

dlstanf2, you are probably right. Luckily there is a guy here in town that is certified to do the dyno tuning. If I can ever get $300 extra I will probably carry it to him. I am married with three daughters so it will be very hard to come up with the cash. Haha. Wyde Glyde Bry, thanks for taking an interest in this discussion and thanks for all the help. You guys are great. Have a safe and fun riding season

Since you have 3 daughters, you lucky man, I'll see if I can download my setup. Might take a couple days to get it done. I'll send you an email.
You might consider BCT baffles, about $89. Sound great and will give you a bump in HP.
Here's my dyno sheet. Hope you can read the numbers, I got about 75HP & 75 Torque.
