Jdmz 12.2 afr is too lean on boost. You can change those afr tables it wont have a negative effect on your basic tune. For example if your tuned at 12.5 afr but want 11 afr just plug in 11. All that will happen is the ecu will make the necessary adjustments to give you more fuel, assuming you have a wideband properly configured ofcourse so the infinity can do that for you

Charper your confusing yourself. Read the manual. There is NO math or calculations to run. VE represents all the math and formulas to arrive at volumetric efficiency number in relation to engine displacement and load. Its dummy proof. As for flex fuel obviously youve never touched the infinity ecu because you would know there are no ve tables for e85! It is automatically converted from the original VE table to the amount of ethanol content in the fuel at the time. You need to get some sleep and take baby steps, no need to be burning up your calculator with aem infinity are you a tuner trying to confuse people into paying you for simple things like setting up a VE table?
Life must be hard.

As i thought charper you dont even know how to open the software and find your way to the ve table. VE is a user input and is the only way to change afr ratios while tuning. newVE is calculated for you once you set up your afr tables. So read a book, dont vomit misinformation, post up a pic of your "VE formula" i need a good laugh troll.

I'm no expert, nor do I pretend to be one. I only comment on what I have personal experience with. For a member who just joined, has a non-running car, and asks every rudimentary question under the sun...you sure do know a lot. I can't argue with pure ignorance.
The expression is ((i0/i1)+i2)*i3 where i0 is lambda1 2 or 3, whatever you have it under, i1 is lamda target, i2 is Inj1lambdaFB and i3 is the VE table 1 or 2. This expression can get more complex than this to account for flex fuel blending, but this is the basic expression for pulling from a single VE table.
Now you can use this information to pretend even harder that you're this expert you strive to be. You're welcome.

Chumper how old are you? Ive had a running greddy kit s2k for years with aem infiity flex fuel ecu, just because im a long time lurker first time poster doesnt mean i was born yesterday. I dont claim to be an expert you just assume that because your an emotional underdeveloped tween. Now quit trolling my posts and grow up.

The biggest hump that was hard for me to understand was that. There is a delay from when vtec hits to where it actually needs the fuel, like 50rpm in my case. So I was tuning for 4600 (vtec engagement) while I needed to tune the spike at 4650.
I got it worked out pretty well now, except the fact that 3rd gear is richer than 4th at engagement.
Do you mind sending me your map? I'm using a second VE table for vtec switchover.
