As the thread would indicate I have a very rich cold start, in the 10 to 11 afr range. It will slowly lean out as it warms but only to 12.5 -13 range. Will stay rich for a very long time ( 15-20 min maybe more ) unless I shut it off and and restart then it will settle down to 14.5ish. Very noticeable when I force open loop. Noticeable on fuel trims in closed loop.
I have IAT and ECT temp factor tables zeroed and the FA cold table knocked way down. Also baro learn is disabled
Is there anything else that would be adding fuel?
