Default Ats evaluation

I have a 2008 vision stock except S1L1 mufflers. Stock air filter
and car tire in the rear. (not that it matters )
I started out at +6 with 02's hooked up. Running half the ride
around 65 mph and the other half running between 70 and 80
mph. Cam up with 49 mpg. (way to lean )
Next time out running the same speeds and same route at +6
with 02's un-hooked came up with 46 mpg (still to lean )

Now at +4 with 02's un-hooked running like the previous runs
came up with 41 mpg (to rich )
Next time running with 02's hooked up came up with 44 mpg
I think this is where I want to be.
All four runs I used 89 octane. Never any pinging or knocking.
I think +6 was smoother going up at 80 mph.
No matter what the setting was I would get one or two pops
leaving a stop sign or stop light on up shifting only.
I feel humidity/due point has a lot to do with pooping

Thanks Visionjohnny, that's great data.
I am also at +4 with O2's connected and getting the same MPG.
I was thinking of bringing the wheel up a bit, but after reading your data I think I will leave it where it is.
Thanks again.

Too much variation to be convincing. I don't think that you are hurting yourself by leaving the O2s hooked up, I just think that there is no way in hell that you rode it the exact same way at the exact same atmospheric conditions and filled it up to the exact same level over and over, over the course of your trials.

The more pressing question I have is...do you feel $200 worth of difference? When you pass a car now does its occupant's fear of your superior power send a chill up your spine as your passing causes them to emit cosmic signals of desperation and submission?

I personally have not noticed humidity having any effect on my POOPING. Greasy food is another story.

I have an ATS set at +3 and run 91+ octane fuel. Sometimes a tank runs as low as 39 MPG and other times I have seen it at as high as 46 MPG on a full tank of fuel. I can often identify the why behind my changes but it is never a tuning issue. If I ride a long distance with a tail wind it gets closer to the high number and with a wind from the front or local trips it will tend to the low side. My timing never changes and my O2s are always connected. In general I see around 41 MPG but riding conditions seem to affect me more than the numbers you are throwing out there. Unless all other parameters are controlled, very hard to do, I suggest that your results are meaningless. Ride a couple of months under varying conditions with each set up and I might think there is some relevance to your numbers but short uses at each condition are more or less useless data. It is well within the variation that happens from tank to tank around here.

how accurate is your speedo Visionjohnny with the car tire? just curious, what are you running for a car tire?

back on topic, with my stock bumflop tire, wheel at 8, thrush packs, lloydz filter i would average 47-48 at. 65-70 mph mostly highway, put on a new avon( larger then bumflop, speedo more accurate now) mileage dropped to an average of 44-45, same conditions, run 91 no ethanol gas.

2012 XR and my wheel is set at +6. I took a long 6 day trip and got the best mpg since I had the bike. Anywhere between 42-49 in all types of driving-- interstate, mountains, twisties, etc. When I got back I installed a set so stage 1 Vic exhaust that I got for a song. Could not tell much difference in power. Then I unplugged the 02 sensors and a noticeable increase or a better word would be a "looseness" or "Freeness" in the way the engine revs. Still have not burned a tank out since, so I don't know about the mpg yet.

Lloyds AF and PC5 coming soon.
