Set the adjustment so it coincides with the wue ending, 160* is normal as most efi engines run at 200* under running conditions.
Run 5-8% authority settings in advanced mode
P=45
I=20
D=3
Give this a try and see how it does.

Thank you!!!
This maybe a dumb question but what do you mean by "Run 5-8% authority settings in advanced mode"
Thanks again!!

Check out the settings, at the bottom of ego box it shows simple or advanced tuning modes.

Set to PID otherwise as you probably know I can't change other settings.

Idle advance and ego connections are not the same things.
Advanced mode =PID mode

Cold start can be hard to pin down, is it long cranking times or a start and die issue?

I am without a PC right now to look at logs. Bump the cranking pw slightly and see if it helps, if it persists slightly increase the ase% (3-8%) in the temp that the issue is occurring
Rinse repeat until you get the start you want.
