I'd try taking the Startup Airflow table (Idle Startup Airflow vs. ERT vs. ECT) table, and multiplying it by ~1.76...you might then find the startup flares way too hard/high, but at least you'll see you're on the right track...you'll probably wind up with less than stock times 1.76, but more than stock by a decent amount. I think you're especially going to notice a startup flare because you've got the startup flare control spark table zero'd out. I've found if you've got too much startup airflow and then the spark is too agressive in the flare control table, the car will oscillate RPM and struggle to idle initially...might even stall...so you need to balance the airflow and the spark control.
If it sounds like it's turning over really really easily, you could also try more cranking advance...but you might not need to after the airflow tables.
