Ok, here is a good file. I got the thing to stop stalling (this was only in the driveway though, no real world stuff) when I jack the wheel, but I think you can see this is unacceptable. It is a very small log, just two blips of the throttle... The first one has the wheel jacked to the stop to put some load on the engine idle, this is common in parking lots, which is when it likes to stall and make me look like an asshole.
Thanks for the help!

If you look at the log when this occur you see that you reach a very low rpm before the engine recover. Low enough to go from running mode to starting mode. If you correct your startup settings you will at least not have stalls because of this.
I recommend:
Set max crank rpm to 299rpm, set crank advance to 10-15deg. I have found that most engines like this.
This will not solve the problem but it can save you a few stalls.
I also found that your overrun fuelcut rpm and overrun fuelresume rpm are too close. Try to keep these at least 400 rpm apart. For example 1400 and 1800 rpm. This is found in the Base setup - Rev limit/overrun/safety dialog.
A more important factor is the ignition advance you run at low rpm, increase the whole 500 column to 15-20 deg, all the way to 100kPa. Now the advance is taken out as the rpm drops as you will have less vacuum with lower rpm.
You can also decrease the ignition advance at 1000rpm at the load sites used for normal idle, 0-5deg works fine and will usually decrease the emissions. This will allow you to use more idle air and is more important and effective on cars not running an IAC.
It's also very important to set the idle hardware correctly, your car seems to idle at around 33% IAC opening. Set 32% min duty in the IAC hardware dialog.
I think that these suggestions will sort most of your issues.
