Even right after i write it, it is not saving it. It was working normally a couple nights ago so i can't imagine it being a wiring problem. Guessing i should have went lc-1...

no the AEM works fine, I run one.

Make sure when you burn the table the car isn't running, just with the key at on position. Turn off the key off, and back to on and check that the wideband output lines up with TS or close to it 14.8 wideband mirros TS 14.8 or close to the number.
If it doesn't let me know what the wideband says when you turn the car on. It maybe in the wrong mode.
Also does the AEM say P0?

Burned the table while at the on position. Wideband powers up correctly, 111,222, etc. then P00 and then 14.8 and after that it goes blank with three red lines ---. Right when i start it up it seems like it wants to work right and gives me a couple numbers before it shoots up and goes blank again.

did you buy this AEM new or used?
you can test to see if the sensor is bad.

do you have a datalog on startup from tunerstudio?
Also updated video

A datalog can help tell if the motor is running lean enough in that area to cause it to be over 18 afr, which is possible and I've seen it happen. Its Also possible that its so rich that it can read it and shows up as Lean which I've seen as well. Knowing where your PW is at idle can be a tell tale of whats going on.

do you have a log of it running for a while longer, when the engine warms up? so all the corrections come off and don't alter fueling.

yeah PW is high, to much fuel, in your idle area take out fuel.
Your wideband is working, your way rich.
25 to 35 KPA 900 to 1101 rpm put it around 35 and see what happens

Sometimes when its overly rich that wideband will read lean just air. One way to tell is look at PW, another way is check for a bunch of black soot\smoke out the tail or smell of gas.

Throw those numbers in red in low rpm\low kpa the ve table and datalog, report back, just want to know if AFR changes while idling to being less rich.

still too much fuel at it, put 30 where 35 is and lower the surrounding ones by 3.

Notice you aren't even out of warmup enrichement yet, so extra fuel is being thrown in as well from that.

Just to let you know you alter the VE table while the engine is on and watch live real time changes happen.
I would select the 4 the dot is idling in and use up and down arrows to change fuel ammount and watch PW and AFR

Did you make sure spark timing is correct?
Also what size fuel injectors?
under startup and idle there is warmup enrichments at the bottom, you can see there the graph and how much it adds

I did not check the spark table. Stock injectors. And i see about the warmup. It stops at 180 and then i logged.
