Northwest Ohio | How many of you are running the PCV with auto tune? I have run one of these on another bike and it is very user friendly. I have also run a DFO (digital fuel optimizer) which is what the ness and Lloyd tuners are. Just wondering if people have a better chance of tuning the popping out with the PCV w autotune. |

Northwest Ohio | Funny not many responses on this. I did go with the Lloyds controller for my 09 ness but I have played with the PCV. I haven't the Lloyds controller yet to start playing but it seems to me that you could tune the PCV for the backfire issue also. I believe what the Lloyd controller is doing to combat decel popping is feeding fuel under 1500 rpm at 0% throttle.
I have an HD v-rod that has the same popping issue as you all describe on the vision but maybe alittle worse. I could get rid of the decel pop but was unsuccesfull at getting rid of the popping between 3000 and 3500 RPM which was the cruising RPM for this motor.I ended up going with the HD supertuner but ran out of good weather to play in.
Don't get me wrong pulse modulators work great and are easy to play with. And I did buy Lloyds over the PCV but I'm amazed not that many people have tried the PCV on the vision. |

Gainesville Fl Home of the Gators | The PCV has only been available for a few of months now in theis aplication. So most people had not had a chance to try it. I have low expectaions for any controller eliminating all the pops though. The issue is not only total fuel cut ot zero throttle, but also the way the IAC is programed. For some reason it seems that Vic wanted to reinvent the wheel with closed loop, and then went with tech that is 20 years out of date to boot |

Northwest Ohio | Hard to believe with the futuristic design of the bike and the 106 engine they wouldn't have gone the extra mile and also outshined everyone on the EFI.
So Kevin, in your own opinion, what is the best cure for the popping issue? You can PM me if you want or post it. From what I have read so far the exhaust gaskets could be leaking, I've read where guys were running diffrent grades of fuel to get rid of it,your cam upgrade seems to help some, Lloyds controller and or valve seems to work. The stock pipe thing (I believe) is you just can't here it.
My bike has 1 mile on it and I'm trying to set this up right before riding season. So far I have ordered atom bomb mufflers,Lloyds controller and plate. I came of a Road Glide and want this change to be top notch. I am very picky on how my stuff runs. I'm an x drag racer and running like _hit is not an option! |

Gainesville Fl Home of the Gators | There is no cure. There are only ways to minimize it. That said a good sealed exhaust is your friend. The bike hardly runs like anything I would call bad. Just a little personality. Remember the one big key. The louder the pipe the louder the pop

Northwest Ohio | Would it be a good idea to change the exhaust gaskets now while I have the mufflers off and the bike tore apart this far or wait to see if the problem shows it's ugly face? |

Memphis | #163, You might as well change over to the old style gaskets for peace of mind since you have it apart anyway. One thing to consider with the popping is the adaptive logic with the EFI system that takes a while to get used to your riding style. It will probably take a couple of weeks for it to settle in. It also re-adjusts when the weather changes dramatically. With all of your work on the front end of this project, I'm sure it will be minimized but just trying to make your expectations realistic. I have Stage1/Level 1 on my '08 and for about a week it sounded like a 12 gauge shotgun (not a pop) going off when I shifted between 1st and 2nd. I freaked out at my dealership and they assured me it was temporary. Shortly thereafter, it was gone, literally overnight. I bought my bike in the late Fall so the weather was all over the place and that didn't help matters. Good luck. Sounds like you're gonna have a killer bike. |

Northwest Ohio | I believe with the Lloyds controller the O2s are disconnected. No learning curve for the EFI. You run off the settings of the controller. |

Memphis | I didn't know how all that interacted. Sounds like you should be dialed in right off the bat. |

Pittsburgh, PA | i just read an article in CycleWorld (april '10) where they reviewed the Power Commander V and the AUTO TUNER.. its on page 68.
They loved the auto tuner feature. They even put it on a dyno to see if it was really doing what it claims to do.. THEN they took the sportsbike and changed the entire exhaust to one that power commander DOESNT have a map for. and then used the auto tuner and it within seconds created its own map and they Re-dyno'd it to make sure the air fuel ratio was that of what they told the auto tuner to adjust it too. and it was dead on each time! thats pretty impressive! Then cycle world said if you bought the pcv and the auto tuner it would be cheaper than buying a power commander and paying a dyno tuner to adjust your power commander and then if you do any more mods to your bike the map that was created for you wouldnt be any good , it would need adjusted again. whereas with the auto tuners no matter what you do to it. (air filters changes, intake plates, exhaust etc) it will then adjust to it.. I was glad to read they actually took the the bike and dyno'd it to PROVE it was doing its job.. good job Cycle World...

PCV with autotune vs pulse width modulators
