Default Better hot start? Startup friction airflow correction

I read that changing this table really helps the hot start problem with cammed cars. My question is how do I know what to change and how much? I would assume I would need to add air but by how much? It's table B4343 with EFI Live

I use that table as well as the other startup correction tables. The key is to add air, decrease the decay amount, and increase the delay amount until you find what the car likes to start up well and settle in to a smooth idle... A good start is to add a couple gms/cyl airflow, cut the decay in half, and add 20 to the delay... then keep working it till you find where it is happy... You may also need to cut down the afterstart enrichment too...

Assuming air / fuel has been dialed in using AutoVE and spark is reasonable, in the scantool under MAPs load the preconfigured RAFIG and log.
