NA6 on DIYPNP, Runs well once started but having startup issues
 

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?

Unfortunately, the attachments aren't downloading properly.

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.

Try flattening out the MAT correction curve above 100 degrees; you may have a bit of a heat soak issue.
