Tune learning area for 14.7.
Tune the rest of the map however you would like.
That's how I tuned my '06. It works very well including adjusting for when I get to go to the mountains with it.
If I understand what 86bgn has done with his tune, he has disabled the learning function. That's OK as long as weather and altitude remain constant. That doesn't describe where I ride though. |

thanks for the replies...
So does anyone know if by disabling "closed loop", means all sensors are no longer making adjustments, or if that means just the o2 sensor is no longer helping with the corrections. Like I said, 08 and up have map sensors, which should cure any question about the ECM making corrections do to altitude. Unless in open loop the map sensor is disabled to???? |

Sorry, I didn't notice you had an '08 model. They are different than my '06. I had to do a lot of learning to tune my bike. I'm afraid my learning didn't include info that would apply to the '08 system. Sorry for any confusion. |

Hey Sifo, no confusion at all... believe me, I wish I could still be using ECM Spy. Just for the simple reason that it seems it was tried and true. When I first got the bike I could, then the dealer flashed the latest EPROM to it and then I could only use TunerPro. There just is not as many people that have experimented with it so I am kind of on my own I guess.
I appreciate any response, so thank you! |

So flash an eprom back into it that has not been locked out and tune it. Did that on an 08 recently.Had to reload the eprom a couple times but tuned it just fine. |

Hey Firemanjim,
I am not sure what you mean...
I can flash any eprom onto it I want. The ECM still wants to learn to 14.7. What did you do to "tune" it. You can smooth the maps all you want but the ECM is always trying to correct to 14.7.
For example how would you tune a 2008 and up for a slightly richer idle and midrange to say 13.2:1?, keeping closed loop enabled that is.
Thanks |

Or do you mean flash the old eprom back to what came with the bike?
If that is what you mean, I do not know what I would use to do that with. I have a BUE2D now, and everything I upload to it has to match that right? I cant just flash it and make it a BUEZD right?
If I could then ECM Spy would still work, that might be cool...

Yes the firmware has to match if you burn the EEPROM.
You can copy and paste maps from other firmware versions with ECMSpy. |

If you are going to tune using one cylinder and do the +2 method on the other cylinder then using VE Analyzer in MegaLogViewer you can change the afrbin table to your liking.

So how do you burn the EPROM? If I could go back to what I had before, then I could use ECM Spy instead of Tuner Pro, then I might have better luck... I could at least play with the middle value of the NB o2 right? |

Whatever the dealer did, they updated it and ECM Spy has never worked since. I can use Tuner Pro all day long and load different "bin" files to my liking. I can change the maps to whatever I like. My problem is, if I used, say your map, I cannot do anything with the pink area... If I richen any of it up the ECM starts tearing apart my tune trying to get back to 14.7 |

I hope my post didn't confuse you, I'm not too familiar with tuning the DDFI-3 ECM's. I did some tuning on the DDFI-2 ECM's. So the MLV and VE reference probably wouldn't do you any good.
You can change your O2 setting in TunerPro under the Scalers section. O2 Sensor Target Voltage. |

ok, target voltage, do I want to set the target higher I guess, for a richer mixture? thanks dude |

I cant find target voltage???

i'm thinking you can change the lean and rich voltages to get your desired AFR. I don't know what those voltages should be though... |

I am not sure, it seems like no matter what the Lean Voltage or the Rich Voltage is set at wouldn’t the ECM still try to reach a target voltage between the two? This is why ECM Spy looks so appealing to me... |

86bgn, you are right about the limitations with changing the target voltages. It is more so due to the nature of the narrow band o2 sensor's behavior. Here is a graph of the voltages from a narrow band o2 sensor that shows how they only provide a voltage switching signal near 14.7:1 afr.

exactly, so if I could set the target voltage for the ecm, to say, 0.7 ...I think that would richen everything up, and I would be able to run closed loop with no risk of the ecm attempting to unravel my custom fuel maps.
Does anyone know how to do that in TunerPro? Target O2 Voltage? |

a wise man told me (xopti) i could lower the rich voltage to lean out my maps for better fuel economy. I would assume if you raise the lean voltage you could richen up your maps. |

Would'nt that be the same as changing your minimum and maximum AFV, just using the o2 voltage? I would like to keep the ECM's ability to have a range for closed loop adjustments. |

My understanding:
The AFV min and max is how much of a correction the ecm can apply to the fuel maps.
The o2 voltage determines WHEN the mixture is considered lean or rich.
someone correct me if i'm wrong. |

Target o2 voltages are where the ecm considers the mixture as correct.
The min and max AFV are the limits to the AFV correction that the ECM can apply. |

As I understand the AFV it's basically a correction multiplier. So if it goes to 105, every cell in the fuel map get multiplied by 105%, or 5% richer. |

Ok, so it sounds like I am going to stay with disabling closed loop, which takes the nb o2 out of the equation...
Does anyone know what OPEN loop learn does exactly? |
Sifo
| | Posted on Thursday, September 06, 2012 - 12:10 pm: |
|
On the older models it was the area of operation that would determine if it was running rich or lean, and then make a correction by adjusting the AFV.
I'm not clear how this works with the addition of the MAP sensor though. |
