Hey y'all. Finally got my afr table and VE table somewhat dialed in, at least good enough to start tuning closed loop idle from what I understand. But before I do that I need to fix my startup problem.
As of right now when I go to start the car, cold or hot, it'll crank and catch and act like it wants to keep idling but then slowly die. If I give it just a little gas on after it catches to hold it at like 12-1500 rpm for 10 seconds or so I can let off the throttle and it idles fine. I've included two log files, one showing an attempted start with no throttle and one showing me giving it a little gas to get it started and idling. I'm guessing it has something to do with the way my ASE / ASE Taper / WUE are set but I admit I've been getting a little lost trying to set those correctly, especially with the erratic weather we've had here lately. If anyone could point me in the right direction or do a sanity check on my tune that would be awesome.
On a possibly related note, I think I'm having an issue with my IACV. I know the first step in closed loop tuning is to do the idle valve test to find your closed/open % values but everywhere I read says to start the test at zero and then slowly increase it until RPM starts increasing to obtain your closed value. With the car idling fine, when I start the test and begin to increase from 0%, around 12-13% the RPM starts dropping not going up, and at around 17-18% it dies. Any ideas?

hm, wasn't sure if that was fixed or not yet.
here's a google drive link: https://drive.google.com/file/d/1_7Q...jSYDQzS4t/view
It will tell you there's a problem with preview since google doesn't know what TunerStudio files are but the download should work.
