I added a D&D pipe a while back and it ran OK with the stock ECM but it has a stumble in the 3k range. I just put a EBR D&D ECM and an open air box on it. After a few short rides and a good 30 min ride above 3k it seemed to run better when i would pull hard from 3k but if i accelerate slow it stumbles several times from 3-4k then is fine. This is really noticable in 3rd gear but not really noticable in any other gear. not sure what it is at this point. I have 20k on it and no problems except the stumble.

cylinder offset in the fuel mapping. your bike is asking for more on one and less on the other in that cell area to refine it a tad further. You can fine tune it with a couple datalogs.

Thanks Xopti, That is what I thought is it needed a few long rides. Should I ride in the area of the problem, 3rd/3-4k? or just 5th above 3k?
