"steady state cruise mode" is correct, and I beleive even with the stock setup the 02 only comes into play at idle and cruise. If I'm correct, it's main function has more to do with the emissions system than over all engine performance. When you hit the throttle all the other sensor take over, like throttle position and load sensors, and say, bubba wants to get going, richen up and inject more fuel.:nod:It was my understanding that, with the Cobra CVT, the only time the o2 sensor came into play was while the engine was in a steady state cruise mode - any other time the Cobra unit would be modifying the signal sent to the ECU (if necessary, of course).
Certainly wait to see what the outcome of the dealer's efforts are first...
This I found to be a problem too. Much harder to deal with in stop and go traffic and stop lights etc.. But even though I have to putter around behind my wife at 20 and 30 mph in these mountains, the are now stop signs for 30 to 50 miles in any direction from my house, and then ther is only 2 or three stop signs and 2 lights. No big city 100 miles from my house, oh how I suffer.Unfortunately, some of us like the looks and basic performance of the bike, but aren't able to go around town at 50 mph in third gear all the time...so we mod))))) Unless you live where there are long open roads, and no cops, it's hard to ride aggressively all the time.
We didn't forget about you just got side tracked.So about the smoke in the exhaust... Lol I can only do what the dealer says since no one on the thread seem to getting anywhere. I appreciate the effort it's not a easy problem I'm having.
Correct, (and this should probably be moved to the tuner thread.) But if most everyone was complaining about surging/flat spots while cruising at certain speeds, and unplugging the O2 sensor made cruising better, then is the tuner actually necessary since disconnecting the O2 sensor will keep it running rich at cruise?It was my understanding that, with the Cobra CVT, the only time the o2 sensor came into play was while the engine was in a steady state cruise mode - any other time the Cobra unit would be modifying the signal sent to the ECU (if necessary, of course).
If one could keep the engine in cruise mode all the time, the tuner would never be used. Since one can't realistically do that, whether a tuner is useful at other times would depend upon the individual engine and modifications to the air/fuel system.Correct, (and this should probably be moved to the tuner thread.)

I did just that. Unplugged O2 with Cobra Slip-On and stock box. Runs just fine like that. The only time I ride at 10-15mph is in parking lots and still haven't had a problem like you guys seem to have. Maybe my dyno butt ain't as sensitive.:thumb:Correct, (and this should probably be moved to the tuner thread.)

Think that would be a ? for Cobra or V&H.I'm curious and it's not clear to me how you guy with 2 into 2 exhaust are collecting the 2 into 1 for the 02 bung to get a true reading off both cylinders? If not why?
I think that's the problem "they're" having Toby. They only have one o2 sensor to use.I'm curious and it's not clear to me how you guy with 2 into 2 exhaust are collecting the 2 into 1 for the 02 bung to get a true reading off both cylinders? If not why?
The V&H Big Radius 2 into 2 actually have a crossover where the O2 sensor mounts.I'm curious and it's not clear to me how you guy with 2 into 2 exhaust are collecting the 2 into 1 for the 02 bung to get a true reading off both cylinders? If not why?
