cold start a/f ratio

Anyone with a wideband tell me what a/f ratio readings you see on cold start up until it warms up fully.
thanks

on idle i get about 13s ish. always seems a bit random, but somewhere round that. i only use the car in the summer though so it warms up pretty quick

I can lean it out some more then ,mine starts around 11 when cold but once warmed it stays around 14.

im on a power fc though so guess it depends how its setup. havnt fiddled for a while so cant honestly remember off the top of my head

mine always started out around the 12's but once warmed up around the 14's

it depends on the temperature of the engine at the time it started up. Ive seen from 11.5 at winter to 12's at summer

Correct me if I'm wrong but I think by cold start he means the engine being started from cold.

Mine is usually between somewhere in the 12s to 13s, thats with fpr@3bar

starts low with 11s/12s then it heats up to normal temperature then around 14.8/15.1 idling
