Warm start issues resolved FINALLY!!!!
A little background:
Last summer I installed an FP Red & FIC 1050's.
After running great for 2 months the car started becoming harder and harder to warm start after sitting for 15 or more minutes.
I replaced and checked MANY different things including:
IAC, vacuum lines, & gaskets. Switched to a DW300 fuel pump too. Fuel pressure regulator and solenoid.
I eliminated many things too thing that they caused the issue including:
EGR, Evap, and other emissions related components.
The whole time I assumed that the tune was perfect because it ran perfect for months before the problem occurred, and tunes don't change on their own.
Well I tried something today and I think I fixed it FINALLY!!!!!!
I zeroed out the last three values in the "Cranking Enrichment Adder (MAIN)" table
and now my issue no longer exists.
I really hope this helps someone,
thanks,
Rob J

THE PROBLEM CAME BACK THE NEXT DAY IT DIDN'T WORK.

That's not what I was talking about. The reason we need to open the throttle is because there is too much fuel, right? The injectors leak fuel after being shut off that's why it won't start... I'm asking if we are flooding the engine with fuel when trying to start it, because there is already so much fuel.
