$0E is heavily documented and has a crap ton of parameters, in fact so many parameters you should be lost about which one to use rather than not being able to find one

there are probably 100 defined tables that control open loop and cold start AFR and its decays

if you don't have such parameters, i have a hunch you're using a crappy XDF. make sure you're using the 'advanced' xdf. see this thread:

and use parameter 'category' view so you can figure out what tables are for what

for starters how bout make the necessary adjustment in 'open loop afr vs temperature vs vacuum' or if it's just for initial start, 'choke afr vs temperature' and 'choke afr decay time vs temperature'
