I have looked through the hac/code and searched the forum but can't find the tables for the warm-up enrichment (choke) amount and decay rate in the $8d code. The problem I'm having is I'm not getting enough fuel during the first 30 seconds of a cold (80degree F) start when first fired in the morning. It runs at 15 to 15.5 afr during that time then settles off around 14.6 before going into closed loop at 130 degree F.

 

Dis kinda stuff?.
