I'm not sure if i should be posting this question here or not.... Anyway, Here are my afr tables. I'm wondering if I should manually adjust them so I get closer to 13.1 in the mid range OR if there is something I sould be logging to compare it to before I do anything. It's from my last autotune session. Ive done a bunch of research, however I'm not sure wht questions to ask and I've spennt hours using the search function and looking on the net.

Need more info on the motor, Cams, heads, pipes, intake.. Did you modify the engine and if so, exactly what.. Also are you running narrow or wide band sensors?
Also I'm your WinPV software program on your laptop When you load your tune and then open the drop down fuel menu and then click on air fuel ratio lambda your desired AFRs come up.. Now if you look in the upper right hand corner where it says show air fuel ratio, using stoichiometric of there's a drop-down menu pick gas 14.7 and then it will give you two AFR numbers that are much easier to read that you don't have to convert from lambda to stoick or gas..
Here's a copy of my set AFR table which is going to be a lot different than yours my motor's heavily built but you'll get the general idea. One more thing I'm running Target tune with wide band sensors...

Just my opinion but you could be setting your targets much leaner below 85 kpa. Have you been mapping your ve table with the Target Tune?

Sorry, 2020 rgs 114 se hi-flow air reinheardt slipons, de-catted head pipe pv2 target tune wide band o2 is all. Wheni get home from work tomorrow ill loook i to it.

Yes I am using Target tune and when it comes to my VE tables, I'm within 1 to 2% of long and short-term corrections.. That's why everything's where it's at.. plugs look great as well..
Ok so I converted it to stoich. My concern is the middle of the table thats all up @ 14.7+ and if I should manually change it yo mirror the cells around them. The problem Im having is I'm not sure what else I should be monitoring to see WHY they're at the number they are. I understand the basics I believe, but there's so much information to learn I'm not sure where to even start I've been running autotune and I cant get the VE table learn % within the 5 % I've seen it needs to get within. I ran the min KPA @ 30 to start with. Then moved to 25 for a couple runs. I've turned the ve off and turned the max spark learn to 10 and after 2 runs it was dialed in @ 1% learn.. It doesn't seem to matter how many times I run it to auto adjust the ve tables its always -1% to 15%. learn on the screen that shows the adjustment % when you exit the datalog screen. I've worked really hard at filling as many of the cells on the datalog screen as possible.
the way I started was I would do at least a 20 minute run with a mix of town/highway. export the data, then flash it with the updated learn.
So I thought maybe I need to refine each session more so instead of flashing each run I started just exporting the data. The next run I would attempt to refine the same auto tune..
Since you are utilizing wide band I would start with the AFR's I have set in my tune and go from there.. Just make sure in the WinPV you have "closed loop" enabled.. 1 is enabled. I would also set my minimum Kpa/Map to 18.. See how that is and then auto turn from there.. You AFR's are way to lean.. Just my opinion..

I agree, they're too lean that's whet concerned me.I'll give it a shot
Well I have to politely disagree. Here is the Lambda table from a 131 With the SE Smart Tune Pro. On the wideband side of the ecm there is no "adaptive" learning. You have to have your ve tables spot on.

I'm not sure what you mean, the auto tune feature will refine the tables somewhat. I need a place to start. I was having knock problems from 28 to 3500 rpm when I rolled the throttle on. in BOTH tunes I had 1 from fuelmoto 1 from dyno jet. I changed to the dyno jet tune because I haven't received an answer in 3 weeks from fuel moto on my tune request. I would rather have my bike run a little rich over lean. I'm experimenting and he's given me a place to start with a decent looking table that is richer in the mid range area than what I have now.
The proof will be in the riding. if it runs like **** (which I doubt) then Ill go back to the drawing board and try again.
What I won't do is partake in paralysis by analysis. Meaning spending a bunch of time navel gazing and trying to make sure everything is absolutely perfect thereby not actually getting anything done .
