I don't see a section for Buell maps.
Is there a website or other area of the forum where Buell maps are posted?

Here is what I have.

Running at over 2000 rpm it is great, I am looking to improve low speed operation.
Idle and slow maneuvering it is not consistent seems to have rich and lean spots (intake pops and diesel black puffs from the exhaust) and surging if the throttle is held at 1500 to 1600 rpm.
I see the timing numbers jumping around at this point and wonder if that is what is causing the wonky low speed ops.

ECMspy does not provide any ignition twiddling neither does Direct Link.
Does the standard ECM have a smoother advance curve?
What are the changes in the race ECM from the standard?

Double checking in ECMspy I see there ARE timing tables, they have goofy bumps in it at 12% & 18% throttle under 1500 rpm, not sure if I can modify this. Also I note that my AFR has adjusted to 115.5% seems like I might need to richen the map in the closed loop area. Not sure what that area actually is. I thought I read somewhere that it was controlled by gear selection, but there is no trans switch and no signal from the speed sensor or speedo to the ECM.

Nobody has jumped on the band wagon here so I will follow up.

I was never able to find any sample maps posted.

However digging through the help file that is supplied with ECMspy I found maps that were used as examples in explaining the software. I noticed those maps had numbers roughly 30 points higher in the closed loop area. I also noticed that the AFV on the bike I was tuning was up to 115%!

So I reset the AFV on the bike and test rode it and it would barely run at part throttle, part of the time one cylinder would shut off, and would not idle. I then raised the AFV back and the bike immediately became more drivable (not right but drivable).

I don't have wide band data logging capabilities yet so, Using this data I richened the closed loop area 15% and reset the AFV to 100%. A test ride determined that I was on the right track. I also discovered while twidlling the fuel map that the front and rear maps were not even close and that the rear map was richer than the front map! (here's the gotchya) The system has the O2 sensor on the rear cylinder, and the system thought the rear cylinder was 15% lean, while the front cylinders map was even leaner! This explains why I noticed one cylinder not firing on the initial test when I lowered the AFV to where it should be (optimally).

So after richening the closed loop area of the rear map I copied it to the front map to get the front cylinder back on track, with the AFV set to 100% I took another ride. I came back and found the AFV had raised to 105% and the motor was definitely happier much smoother and more tractable, and the cruise throttle requirement was reduced. I then bumped the closed loop numbers a few more and reset the AFV, test rode and came back at 102%.

Bike cruised so smooth and idled better yet. Bike leaps to 80 mph and wheelies at will. Without data logging this is the best I could do at this time. All in all a very positive experience I learned a great deal about the systems behavior.

And the best part, ZERO dollars (besides the interface cable, which I made)!!!
Anyone want to give this a try on their own machine contact me, I can build you a cable. (Ships in a padded letter envelope)

interesting/good info, thanks for posting it ryder rick.

I have been fidling with my X1 & ecmspy, but have had limited results. Sounds like you have a good setup. Would you be willing to share your fuel maps? Bill
