leans out after hot for awhile
#7
the o2 is right after the header and it shows an afr of 16 at the beginning. sometimes if you dont wait awhile before starting the car the o2 wont change much at first. Its not the beginning of the datalog that matters so much, the car runs fine for the first 3/4 of the datalog its the last 1/4 or so that the problems creep in and makes my idle lean first then my accel enrichments appear to stop kicking in under acceleration

One thing I do notice is you're using a TON of Air temp based enrichments. The whole map has tons of extra fuel being added based on your AIT temps. I'd try making your clt-based air density table all 100% first. However, even though you are adding 41% extra fuel in a lot of spots, yours still pegging lean.
Just looking at your fuel map the values look CRAZY high. I cant understand how you're making over 5mpg.
What happened at 68929 sec? did you stall out? looks like it injected a **** ton of fuel and backfired and kill the motor.

the AIT stuff was just added recently, its not part of the tune regularly, it has been doing this for a long time now but wasnt noticeable until i started getting the car closer to drivable. i changed them back and tried putting it on coolant corrected and my idle got a bit better but it will still do it. my ve values have been based off the ve analyzer . my car has been built to flow a lot more air than stock port/polish, 1mm over intake, glass beaded intake mani., full exhaust. i do believe it stalled out around 68929 sec, the idle was yoyoing a bit when i just stopped in front of my driveway then when i started to drive up the driveway it stalled.

Well, here's the thing... on that log EGO is only correcting at most +/-5%. So changing that will do nothing. Your AIT corrections however have it adding over 40% more fuel throughout most of the map. I have a feeling the o2 is bad so VE live is adding fuel based off the readings, then to top it off your insane AIT corrections table is dumping in even more fuel, look after 68670sec when the temps hit 90°F, making the thing drive like *** from being too rich.
Disabling o2 will do nothing if the current fuel table has been altered based on false o2 readings.

i have changed the AIT corrections back to the base map settings and it still goes lean doing the same thing. the table works fine for the first 20 min. of driving then it slowly gets lean on idle first then the accel enrich doesnt work so when i accel it leans. it did all of this before i ever touched the AIT corrections

it's always going to show lean IF you have a sensor that shows lean for no good reason.
Then it's going to run like *** if you tune off a bad o2 sensor that likes to go lean (VE Live will richen the fuel map [and yes your map is bad, it's disproportionally rich as **** in areas it shouldn't be], and then add in a **** ton of extra corrections....uber rich. like bill gates rich. like obama money rich.
or you have a plugged fuel filter or something.
