Did you let the autotune adjust while at idle? Recalibrate the WB. It seems like the ecu isn't getting wideband input so ur afr/ve tables must be whacked. I can't open the file u attached. It just shows a bunch of numbers and letters on a white page. Im using a mac.

if your AFR gauge is reading 22, then it's not working correctly. that means no fuel.
REQ_FUEL was a set and forget thing. it's literally a multiplier on the fuel table.
i had you add/subtract it to see if you were too rich/lean for initial startup. You should only have to change the number if you changed injectors, and then it's simply math to figure out what to change it to. You need to go back to the initial number that was loaded in it. a REQ FUEL of 25 means the MS is injecting a crap ton of extra fuel (twice what it was set up for), so your fuel table is going to look really small compared to most others to compensate.

Thank you, this is what I needed to be told. I had switched my battery out during the 2 month sitting period, I probably need to re-calibrate due to that. I'm an idiot lol. I am going to re-calibrate today, and start over. Thank you for telling me this.

So I re-calibrated my sensor. I then got into autotuning and at first my gauge was reading around 12, then slowly as the car warmed up and sat for about 7-10 minutes the AFR gauge started going higher and higher until it reached 22.4, and couldn't start without some throttle.
I went back to the tune I had saved yesterday, and it started up fine, but the gauge is now reading 22.4 and at idle it's running okay, but when I give it a small amount of throttle input the car wants to sputter and then it dies. I can see the autotune changing cells like crazy once again, but my gauge it still at 22.4. I saw the gauge change from 11ish all the way up 20 and it was changing numbers based on the autotune... Should I recalibrate it again?

No I haven't. All I did was go into the VE analyze and click start tune. When it was running pretty well I clicked apply, that made the car sputter and the autotune started adjusting harder. Is there a resource or a step by step on what I should do? I've read things on the forum about turning settings off for idle/warmup, but I have no clue what I am doing lol so I don't want to start messing with things that could mess up the tune, I also don't know what settings I should be looking at to see what I can affect safely.
Checked settings, mine are:
accel-pump AE
EAE
off

Any suggestions on where I could look to fix the configuration?
Also I should have mentioned, since the AFR's were only out of range by 2 points I clicked autotune to see what would happen, under active filters it was yellow and said o2 out of range. I don't know if that piece of information is helpful or not, considering we already know they are out of range.

I followed the instructions I found here :https://www.diyautotune.com/support/...novate-config/
I set it to the lc-1/lc-2 option.
