The only other thing is, with the square idle I may be running a bit fat on cold start enrichment. Just a bit - due to my own fiddling with it before I did the square idle. Probably not a good thing to have going on given the Uly's penchant for fouling. We'll see.
It is extremely handy to open two instances of ECMSpy to compare maps. VERY handy. I suppose you could open as many as your screen could hold (as long as you don't do that when connected, just for looking, contemplating, and planning).

Well...I've done something wrong with ECMSpy. I'm very tech savvy (it's my job), so I understand what to do. I've read the complete tuning guide and all the posts on this site.
So...I follow the instructions. I save my stock map and EEPROM. I change the 8 cells for the square idle (4 for each cylinder).
I start the bike. It idles smoother for sure. Even cold starts well. I'm very excited. Lot less shaking going on.
All that ends at 4500rpm, where I now have a BIG hole for some reason. I mean a HUGE hole. I didn't change anything else. Not one other cell in the map. I tried going back to stock...but the hole is still there. CRAP! What the hell did I do???
It's very dramatic too. You can be accelerating at a steady throttle, and when it hits 4500rpm, it's like you stabbed the brake for a millisecond. It will actually pitch you forward a bit.
I have no idea what the heck I did. But something isn't right.
I'm going to need to get the sucker on a dyno or something and find out what's wrong. I don't want to just try to figure it out.
I need to find someone who can help me sort it out.
Wish I would have left it along. Bike ran flawlessly other than the rough idle. Now it idles great, and comes off idle without any hesitation, but right in the meat of the powerband where I ride mostly...there is a big hole. I guess you can't have it both ways. The bike now runs great under 3000 rpm, where previously it was almost unridable. It seems I've traded low RPM smoothness for high RPM power, and I'm a high RPM guy. DAMMIT!
CRUD! What the hell did I do wrong?? |

Chad,
I have not heard of a situation like this before.
If you can, post your fuel and timing tables.
Did you save your config, before you started modding? If you did, just reload the original. |

I did save the stock maps. I tried reloading them, with similar results. In fact, the funny thing is, the idle didn't return to it's previous state when I went back to stock either.
Here is the map I am running.

My values look dramatically different from yours.
Are yours from your ECU???? |

Not an expert here... but I have an Race ECM and an eeprom update from XOpti. When I loaded my new map/eeprom... He said to make sure to reset your afv to 100% and then ride for about 10 miles so everything learns properly after the change.???
I would assume that would make sense for any change to the maps etc.??

I did just that.
I reset the AFV to 100%, and went on a nice ride. Making sure to keep the RPMs in the "closed loop" area. |

I loaded my original Race Map into ECMSpy and compared to the one you have above. They look the same...So, my guess is the map itself is ok. |

Did you by chance disable the interactive muffler setting? |
Gamdh

Race ECM doesn't have support for the interactive valve... so it should be disabled. |

I just compared the timing tables in your file above (download link) and the stock Race ecm data.
Front Cylinder was identical
Rear was drastically different?
a bit off topic..
I also noticed a file format difference. I originally saved the eeprom data and fuel maps in version 1.7.8 of ecmspy.. when I loaded the maps in this version and exited it keep asking me if I wanted to save eeprom changes.. even thought I had not made any. In th older file version I had to loadd the full eeprom data to get the timing tables.. apparently now it is included as part of saving the fuel map.

I can't view the attachments....but that would make sense if the rear had issues. It really does feel like I'm dropping a cylinder at 4500. |

Keeping it simple.
Which airbox, air filter and cover do you have? Which exhaust. How do you ride upper rpms?
I gotta ask ya, have you set your timing straight up, and tps after that?
Would it be possible that you may have an intake seal leaking?
Your map look good. My only concern was that it seemed a little light in the midrange. Have you data logged a base map from xopti? He has a driveway data log that takes place in neutral with the temp up. The first map he sent me back from the driveway datalog was the best power map I have tried.
The sequence is important:
Set timing straight up
Set TPS
Set Idle and adjust Idle EGO.
Data log and adjust fuel map and timing.
Test ride and smile. |

The question is.. how did it get changed. One of the reason's I mentioned the file format difference above (since you didn't change anything)... maybe there is an issue with the changed file formats and the version of ecmSPY?????? Just a wild guess...
I have the stock race ecm eeprom file (BUEGB231 04-02-03.epr) if you need it let me know. This includes the fuel maps and timing tables.

Wow! That timing is NOT right.
I'm going to load the timing data from your file into my table and go for a test ride.
I think the software might have screwed the upload or something. That's not even in the ballpark, and it's RIGHT where I'm feeling the hole.
THANKS! |

God bless you guys for your help!!
Second gear wheelies are BACK!!! A big Tennessee YEEE! HAAAWWWW to ya!
Don't know what pooched up the rear timing values. The only thing I would guess would have been a error checking problem during the transfer. The rear map was showing as pooched in both the stock config I saved, and the modified one, so the error carried forward to the new map.
Once I reset the rear timing values to those provided by Gamdh (thank you!!), the bike is normal again.
Oh, and the square idle is working great too!
My bike has been saved! Can I get an Amen!  |

Hey all. Just getting into ecmspy. It is my understanding that the rear cylinder is to run richer than the front. If this is the case why is my rear cylinder map showing lower numbers? I thought the numbers of the map were the injector pulse durations hence more fuel. I must be missing something here. |

It's richer in some places, leaner in others. Struck me as odd too, it's like two different motorcycles. I would have thought both cylinders would be almost identical except for the rear being richer.
Wow, Chad, that is a spooky thing. Glad you got it sorted! You should ping Gunter on that one. I wonder if it was the middleware/firmware on your laptop?
VERY strange that the timing map go SO screwed up. I think posting the stock maps is a very good idea; gives another disaster recovery option. Xopti has some posted on his website as well.
Note to self, always have the stocker map and when making changes, first back up what is in there by fetching & saving the EEPROM, make changes, reconnect COM to the bike, burn, cycle ignition, do ANOTHER fetch, and verify by perusing the fuel and timing maps and comparing to stock and to the last backup. Opening a couple instances of ECMSpy is really helpful for that, but I would not be connected to the bike when doing so, JMHO. |

Now here is a question:
It appears that the .txt file for the EEPROM is all that is needed to load an EEPROM file. So why do I also have the .epr? What does it supply - or is it just another format (binary)? Can't open it without also having the .txt, so whahachee? |

BTW, 48.8 mpg on the last fillup. That includes two hours of flailing about in the dirt on a trail I had no business being on, where I am quite sure my mileage sucked.
The turn signal was in stock at the dealer on the way home, too...
Did you know Ulys can fly? They can. Especially if you find yourself in a tight spot facing a dip and rock and REALLY don't want to stall, so you follow the time-tested "when in doubt, gas it" protocol.
1203cc geared tall in the rocks can make that rear tire behave oddly as it goes sideways, both tires in the air, and the ride come to a bad end, didja know? LOL
Won't do THAT again.
