I believe that lambda makes the adjustment automatically and that it will attempt to give what is asked for independent of the fuel type.
I am not saying that with E10 your tune is running rich. (I do believe that if you were to find real gas though, it would be rich.) When it was "dialed in" via AT the resultant VEs were created based on the fuel that was being used at that time. Some on this forum go so far as to create different tunes via AT with different fuel octanes in anticipation of what may be available on their road trips.
I would keep your train of thought right where it is and not go nuts over this stuff. I do know that when I was my recent road trip to North Carolina, the gas was definitely better then the stuff we have here. My mileage and performance was a lot better. I definately notice stuff like that on a 1200 pound trike.
My bike runs fine, no pinging, good performance, not overly hot and fuel mileage is comparable to what others get with a trike. It's as close as anyone else could get it without a dyno (been there, done that with other bikes).
Sometimes I feel that this is a complicated subject and with my very limited understanding, I don't explain things quite right. Sure wish the brain trust would offer their insights.

Delta....ok i was backwards. Got it. Trust me i wont worry about it at all. i have also taken my bike up and down the east coast. Not had a problem yet. i was just curious.

Auto Tune
I'm a novice rider, using a Flash Tuner for the first time, just want to know if this is the right way to tune using PV.
BIKE SPEC: 2013 FXDB Street Bob, 106" S&S Big Bore, S&S 585 Cams, Ported Heads, Screamin Eagle Heavy breather, D&D FatCat 2-into-1.
Got a map from Dynojet, bike was still misfiring, DTC throwing up 'Engine Rich' codes. I setup auto-tune and followed this:
1. Let the bike idle for 5 mins, some 40 Hits
2. Exported the Learned Auto-Tune values into a slot and applied it, again enable Auto-Tune
3. Took the bike for a spin with a pillion rider for 10 mins, 80 hits, exported, applied
4. Repeated step no. 3, 3 times recursively
I cannot see any change in the AFR's or the Timing of all the Auto-Tune iterations so a bit puzzled, what really changed with Auto-Tune? Have no access to a dyno or professional tuner although Bike seems to run a lot better now.
Further, I want to improve the throttle response and low end torque. What do i tamper with ? Should i continue auto-tuning ? Am i following the right process ? Will deeply appreciate any input. Thanks.
Note: Every time i applied a Auto-Tune map i reset the learned AFR when asked

There's a bunch of folks here that are more than willing to help. But, we can't keep rewriting the basics over and over every time a newbie comes on board.

This is half the problem
It doesn't sound like you've done any reading on your own. Sit down and read the last 100 pages. Every step and what to look for has been gone over a bunch of times. Being as new as you are it's important to understand as much as you can BEFORE you start running AT. Read read and read it again. Open up a word document on your desktop and copy and paste all the important threads and responses.

How about a page #.
Everyone states the same as you. Yes, it would be easy to read if this thread was 10 pages, but no, its going on 500. Time would be better spent reading about fundamentals of tuning rather than reading all 490+ pages here.
The new guys here are askign for direction in the basics!

I'm a rookie so I'm a bit closer to your level. Read post 4883. Auto tune lays down the groundwork. That is what you are doing. This has to be done so manual future changes to the afr will work. you need to set up winpv in pro mode to acces the info you need. Change the viewing of the ve's delta, (difference) to observe your progress in %. Get the log tuning software from dynojet and get excel to view logs. This is when it all starts to make sense. It's important to me to eliminate knock events so me and log tuner will retard timing on those cells. I will worry about fuel later. Almost everything you read will start to make sense once you are over the hump.

after a few more runs youll see your VE's aren't changing more than a few %. then you can move on to timing and AFR. Definatly read the last 100-150 posts. lots of good info and tips on hitting as many cells as possible.
I'm still learning and not the best at explaining things.But don't worry the process works. we were all where your at once.

Gents, i've been reading threw this and in the beginning I read a lot about WinPV and PV log tuner. Now i dont see much about pv log tuner.
Is PV log tuner still needed? am I just using win pv?

you'll want to compare your latest AT.pvt file with your previous AT.pvt file.

Then with accurate VE's based off my bikes set up I can tweak?
