Ahh yes I see the light now,that explains a lot and makes things a lot clearer now.So all I need to clear up now is whether or not I need o2 sensor eliminators if I buy a PC111.Then I will be on my way,I guess.And thank you for the information Mick
nobody
All I need to do now is find out who has the best prices on a PC111.And Thanks again for that info Mick,as I was looking at some of the maps available and they were saying with o2 eliminators fitted,and I didn't see anywhere on the web site where it says that the eliminators were for sale for anything but some jap bikes,so your explanation clears it up completely.
cheers
I think you will find the surge is related to the fact that it is running too lean at light throttle,my Roakdking does the same thing,will fix it on Tuesday hopefully,when I richen it up a bit.
I sent the following text to Dynojet (makers of PCIII)
When purchasing last month there was no reference to P/N ending in EX on the web site. Is this something new for the 07 Dyna? I have noted that the Power Commander P/N 814-511 states ''for racing vehicle only''. On scanning your web I not that there is now listed an "EX" version. Is there any difference and can I use the unit I have (i.e non EX) on the road. I have an international standard 07 Dyna Street Bob with electronic servo-controlled butterfly valve. I am replacing the standard exhaust with a Vance and Hines Short Shot Staggard P/N17217. It looks like the non-EX units have a full map capability whereas the EX has a limited map capability. Thanking you in advance.
Their reply was:
You are correct in your analysis. The EX power commander was recently introduced for those areas that have more stringent emissions controls, i.e. (Calif). In order to be certified as street legal in those areas the power commander cannot make fuel changes in certain areas of the fuel curve. The regular power commander now designated as "race ready and for off road use allows for complete control of the fuel curve. It is up to the individual consumer to choose which one he feels is appropriate for how he wants to use his bike.
Thanks for your inquiry. The EX Power Commander was recently introduced to accommodate those riders in areas of the US that have more stringent emission standards and regulations about aftermarket products being installed on street legal bikes. It has been certified by the Calif Air Resources Board as street legal in California. In order to obtain that certification there are certain areas of the map that can not be manipulated or changed, the amount of timing adjustment is also limited, there is no button adjustment feature, or cylinder trim capability either. The EX power commander retains the stock O2 sensors and closed loop system, where as the regular Power Commander utilizes our O2 sensor eliminators, thus allowing full control of the fuel curve. With the introduction of the EX Power Commander, the regular Power Commander III USB was given the designation of "race and off road use" to distinguish between the two. That power commander is the same unit we have marketed since 2003 and allows full adjustment and manipulation of the fuel curve and all the other timing and adjustment features available with the power commander. We make both units available and leave the choice of which unit to purchase up to the individual consumer, based on their anticipated use and or local regulations. Your plans to change the exhaust on your International standard bike would necessitate the use of Active Exhaust Bypass p/n 76423018 to prevent any error codes being displayed by the removal of the butterfly valve.
I am running the standard PCIII and am happy so far. Still need to have the bike on a dyno. Hope all this helps.

Chrisc this is the thread.
Can anyone recommend a place to cut out my exhaust valve in Adelaide?
Thanks
Iv'e had a PC 3 fitted and full set of V & Hines pipes but does this mean that that valve thing is still active or has that all been bypassed now and how will i tell ,is there somewhere you can see this thing easily. Also if its not removed but blocked open do you still get the HP gains or not . Cheers Wayne
do u like the differance ? or u dont realy feel it ?
After the valve I changed the mufflers to S&S slip-ons. It is difficult to tell what has made the difference it does feel a little more responsive but not sure if that is just the extra noice from the mufflers.
