Hello I?m looking for the start up airflow table for the 99 software having a cold start problem now that it?s like 30 degrees In the morning if anyone can point me in the right direction, I?m at work at the moment so I cannot post up a tune

Without file hard to say… could be fuel related and just not enough air.. I assume this isn’t a stock car anymore

Try starting here if your wanting to adjust the starup airflow.
Press CTRL+N to open navigator, Type in 12146 and it goes to this table.

problem is only when its cold i tuned the start up air flow but made little difference, car stays lean until up to operating temp

The IAC counts are maxed out in your log. The IAC cannot give the engine enough air.
Here is a link we send to our customers on how to adjust cable throttle bodies.
