[QUOTE="ELP_JC, post: 268626, member: 6177"] Hey Gary, thanks a lot for that interesting piece of information. Didn't know our bikes didn't hold 2K rpms. We have the same COs for our '07s. I honestly couldn't tell of any difference from 0 to +7 (tried 4,5,and 7), other than the temp went down 1 bar, but that might have been coincidence when I looked at it. Engine still stumbles when blipping the throttle quickly in any of the CO levels mentioned above. I think it surged worse on +7, so I agree the most for my bike is +5. Maybe raising the idle a bit more eliminates the stumble while blipping, but it does not affect rideability for what I can tell. Please let us know when you finish messing with the CO levels and if any setting eliminated your problem. But just like you said, none of us ride there while cruising, but that might be part of the reason why the surging, no? And I also volunteer to try an '06 ECU, even though I'm 120 miles away from the closest mountain. Best would be for 2 people who live in the same town near a mountain to just swap ECUs and go for a ride. And yes, the solution is in the ECU; no question about that. And I bet it's probably the same fix as the FZ1, since they had identical issues... and both are 'world bikes'. Take care. JC [/QUOTE]
