I do not have any startup sections under airflow for my ECM unfortunately. Right now when I start the engine under ~160*F it flares to over 2,000rpm, which is stupid loud with straight pipes. Can you help me get it down to 1500 rpm? I have played with startup airflow in park as well as dashpot decay with no impressive results.

Your idle airflow multiplier tables axis's are run time and ECT temp.
At 160*, it would be targeting 800RPM with the start up ECT adder, while airflow tables are asking for about 30% more airflow for 20 or so seconds. Probably could find a big improvement with just copying what is in the drive multiplier to the neutral multiplier table in the higher coolant temp columns.
