Your base running airflow numbers are not realistic. Put stock numbers back in, mulitiply table by 1.25, find and run the Russ K idle airflow config. Your ve table in the idle area looks low, I would revisit your 800/1200 columns also.

well i made changes still same thing.
i did a cold start data log. tps 5% is me holding the gas since it wont stay running on its own.

I'm running lucas 42#
looked into my tune file for kpa 60.64 61.01 61.38 61.76 62.07 62.50 62.87 63.25 63.56 63.93 64.36 64.61 65.04 65.35 65.73 66.04 66.41 does this seem right?

Post the tune you made the log with.

Although it's possible to tune around the wrong ETC scalar, it makes airflow calcs and everything wrong. You might want to put the right scalar in there, starting with something in the neighborhood of .0190.
Your IAC should be logged so you're able to use it for feedback. If it's wide open on startup and you're unable to start it without some throttle, then you might need to open the throttle more and reset the TPS. One final tip: having fueling off can force you to have to try to compensate with airflow. If you're having to open the throttle to get the car to start, if the fuel is the cause, it would mean it's too much prime shot or startup fuel causing it.
