Gainesville Fl Home of the Gators | Atomization is optimized with the advanced timing. Intake valve is well open before a shot of fuel enters |

Atomization is optimized with the advanced timing. Intake valve is well open before a shot of fuel entersDoes the factory not use this improved timing due to emissions? So it richens it up?
Thanks for the explanation. I've been looking on the internet but I can't find any discussion yet about advanced fuel injection timing in anything besides diesels. I'll keep looking. Obviously if it work on a bike it must be something commonly done in the car world.

ECM in your basic econobox is in the area of 20 times faster, and more powerful then in a Victory. What we have is closer to a 1973 Super Beetle. The car is able to advance and retard fuel timing based on temps, load, mixture, and knock sensor; all by itself. |

Gainesville Fl Home of the Gators | Nothing wrong with a slightly stupid ECM. As long as it works[which it does] and reliable[which it is] |

Vineland, NJ United States | I installed the ATS set to +4, bike runs strong however I wanted to throw this observation out and see what you guys think. This past weekend, I went on 3 day trip with passenger, bike was loaded to gills with "stuff". On really heavy acceleration I would hear pinging from under the radio console from engine area. Is that anything to worry about? am I doing damage? should I turn it back to +2....what do you think? |

Did you reset your fuler after the the timing wheel was instaled |

Vineland, NJ United States | I did not reset the VFC III, it is still set from installation of cams & intake. I never messed with it since installed by Vic mechanic. But it didn't ping before I installed ATS or at least I never noticed it if it did? |

Mechanicsville, VA United States | If you're pinging down shift at least one gear or you will be doing damage.
I have the ATW and the no good for nothing PCV with Auto Tune and I set my ignition timing at -1 at 2500rpm's and then -2 above that all the way to 6250 rpm and I haven't heard the pinging since. Runs strong. |

New Orleans, La, | Diamondbird I'm confused by your post. You say you have the ATW installed at 4+ degrees and the PCV and you set the timing at -1 below 2500 and -2 from2500 to redline? How and why did you do that. Also do you or do you not have Lloydz massaged ECM? I asked because I'm looking at doing the ATW and intake stacks and I already have thhe cams, Lloydz ecm and VFC III, and top filter and trying to get all the info I can so I can make an informed decision. Thanx guys for all of your discussio this is great and does influence my choices. |

Mechanicsville, VA United States | V92SC, Not all bikes can take +4 timing as mine was pinging so I reduced the timing with the PCV, you set the ATW at +4 and with your computer you can make changes to the ignition timing with the PCV.......The PCV will not make ignition timing changes below 2500 rpms I am told,my ECM is stock. I think you will need someone to dyno your bike to get the right size Stacks installed. |

Vineland, NJ United States | Just an update. This morning I turned the ATS from +4 to +2 and then took a 100 mile ride (with passenger), put bike thru the ringer and got no pinging or engine noises at all. So not sure if the +2 is actually doing anything over stock, but the bike runs good now and no more pinging so I'll leave it for now. |

| if you had fuller set on one setting and then put in the gear and advance that by 4 degrees it only makes cents you would have to change fuller cause your motor is now 4 dredges more then stock so now you have to change fuller |
