San Clemente | Just installed a PC V and Autotune. I was wondering what a good idle A/F ratio is. Anyone have a suggestion? |

Pittsburgh, PA | power commander goes for 13.2 to 13.5 ... what is your setup.. i ask cause if you have a map simular to one they already have the auto tuner will go to those settings.. |

San Clemente | It is a Power Commander. They do not map idle. |

Albuquerque, NM | You have to download a map from their website based on the config. of your vision. Maps selections differ on your config. stock, pipes, air filter upgrades, etc... You connect a laptop to the pcv5 on your bike and download the map to the pcv5. Then you can play with those base map settings.

Pittsburgh, PA | just wondering why you would think it needs changed if power commander themselves dont think it needs to be? |

San Clemente | I now have the ability so I figure why not. I also noticed this morning that at idle the front was mid 13's and the rear was low 14's. Seems to me that they would want to be the same. I haven't contacted PC. |

Pittsburgh, PA | aside from your idle reconfiging that you want to do.. do you think the auto tune was worth it? have you ridden with it yet? I was just curious if people "FEEL" a difference with it.. |

San Clemente | I'm thinking it is. It seems the bike pulls harder. I was going to say smoother also but the bike really was smooth to begin with. Some time soon I'm going to do a few dyne runs to see if there was any kind of performance gain. |

Yes they do....
My PCV has adjustments in the zero percent throttle column, including in the 750-1250rpm range. It does work if you set a value other than zero there.

I like 13.5 to 1 at idle..... |

Pittsburgh, PA | the reason i asked if it was worth it or not is.. i have a s1l1 setup with the performance air filter and the lloyds top filter (gen1). power commander has that Exact map setup for my 2011 vision! same pipes and same air filters. would it still benefit me to get a auto tuner? i really have No plans on adding or removing anything from my setup. im just so curious about this.... |

San Clemente | For me it's sort of worth it just because it's something I can play with. I like to tinker. In your case one thing to consider is every bike is different. What's good for one bike may not necessarily be the best for another. How much different I can't say. I would imagine the one map is pretty close. |

I was responding to the response to down load a map. Of course you can map it, but any stock PC map and target A/F ratio map does not map idle hence the zero. Yes I did know it can be done hence inquiring about a good target. |

Pittsburgh, PA | i wonder if the reason why there is no additional mapping of the idle is because there is no additional air being sucked in (throttle not being open) and maybe you can only let out as much air and your pulling in ? so really at idle its acting like it is in stock condition, because there is no need to act other wise? |

San Clemente | I think they don't map it because to try to map idle other than to sit at idle and let her tune would get messy. So the way to do it is in put the target let it tune accept changes then remove the target for idle so it doesn't continue to tune there. This would appear to be too complicated for the average Joe. |

SoCal HiDesert | Just curious, why do you want to adjust A/F at idle? |

San Clemente | The two cylinders were different from each other so I thought I would. It all goes back to the manufacturer tunes for the EPA, now I can tune to what's best for the bike. |

Just curious, why do you want to adjust A/F at idle?
Same reason why you tune it anywhere else when running an add on fuel controller (and thus bypassing the onboard EFI closed loop system)... the mixture is usually off. I believe one poster already indicated the discrepancy between front and rear cylinders, one is in the 14's, and the other in the 13's.... ideally, they should be the same. Idle should be around 13.8:1, but I prefer a little richer than that....as it tends to idle smoother.

I have PCV with Autotune. Late last summer I finally made it down to Lloydz to get the CAMS and reprogrammed ECU. I had a conversation with him regarding about auto tune and basically he wasn't sold on it too much. I asked him if I should take it off....and he said it would be fine with it on after he tuned it. So was auto tune worth it.....not so sure. If I added anymore items....which not sure I can or will. The auto tune would work to make sure the A/F adjust to the new setup. If the bike's performance goodies are kept as is, Auto tune probably isn't doing to much to notice a difference.
Now when I first got PCV with Autotune installed, I did notice a positive throttle difference. My reference point was with a bike with S1L1 and Lloydz intake plate.....to a bike with that plus PCV & Autotune. So if I just got the PCV, would I notice the difference without Autotune? Good question....I couldn't say.
Doing this all over again, I would make sure I had Lloydz do his magic and go with what he recommended. If it is programmed correctly at the start, Autotune isn't doing that much for you unless you are adding additional components. |

Chesterfield, VA | Dumb question here...I thought the PCV was an open system (with the broad range O2 sensors) and therefore would bypass the ECU. I also have the PCV w/autotune installed, and was under the impression that the reprogrammed ECU would be a waste of money since all the A/F input data was coming from the PCV and not the ECU. So how screwed up is my reasoning?? |

Troy, NY | The PCV still communicates with the ECU. A reprogrammed ECU by Lloydz change the timing of things with the bike. I don't know the technicals. The PCV or other fuel controllers do just that control the fuel/air mixture you want. I could be wrong though.... |
