I had some loud as hell gunshot popping on decel when i put the Short shots, SE a/c, and PC III on my bike. I added 20 to the 0% throttle position on the map from 1500 rpm up and it fixed almost all of the popping. I still get occasional popping but not even close to gunshot sounds now.
Had my bike dynoed cause it was popping horribly and was sluggish in midrange. The fuel curve was all over the place. They straightened that out and put a full custom map in it and it runs awesome now, fuel curve is nice and smooth. Still gets popping if I let off the gas and not clutch as it decels. It is considerably less than before the dyno, but still seems like it pops more than I'd like. Before, man, it would pop when I shifted gears. Better now, but I was wondering if I could do what you said above and not screw up my custom map? I'd just like to see if I can improve or lessen the popping anymore. I have the hooker troublemakers which are prone to pop, so I may just leave it well enough alone. Thoughts?

You won't hurt anything by adding some to the 0% throttle position. All you have to do if it doesn't help is just change it back to what it was before. I'd try to add 10 at first then increase it by 5 until it makes you happy. All it is doing is adding gas when you close the throttle. The worst thing is it could decreae your gas mileage with stop and go traffic.

Yep that's how you do it. Before you begin, save the original map on your laptop if you haven't already. There are detailed instructions that came on the cd with your PC or you can download them off their site.

hey guys I just installed a PCIII in my 2007 nightster, it is stock in every way exept the guy who had it before me punched out the exhaust,
my dealer recommended I install it to richen up the bike,
I'm running...
*Advanced Map* Stock exhaust, Stock air filter, Stock ECM, Dynojet O2 sensor eliminators installed, Rev Xtend enabled, Fuel table 1 is rear cyl
and am not sure if its the right map, I had a slight poping sound from the exhaust before I installed it but nothing to serious,
but now after the install I get alot more poping and its alot louder too,
I have included a few pix of my spark plugs before I installed the PCIII
I'm no expert in reading them so I was hopeing some one here could tell me if I was running to lean?
also can someone tell me if I'm running the right map?
or recommend a better one?
Thanks in advance.

thats good to hear, I was still wondering about the plugs,
I'm ok with the poping (I kinda like it) as long as I can be sure its not harming the motor.
I'm going to try and set the 0 column at 5 from about 500 to 1500 RPM and see if that helps with the black smoke.
