5.3 Poor Cold Start

[Hondaeater]

The issue is it's got to be less than 40 g/s. Anything 40 and greater will absolutely not work. To this table right the fueling and timing need to be tuned first. Then watch LTIT and STIT for how much correction its adding. This is simplified just to give you an idea and words to be able to search.

That is good information to know and thank you for sharing that.
This is a DBC throttle body looking at system tab, 92mm from his original post and should not be anywhere near that high of BRA.

Can someone look over this tune file and tell me why the Cracker air is not present. It appears randomly ? Clutch in would do that but it should be showing up while under acceleration.
I am at a loss. If you view this log about 3min 3sec, right at the 12mph it triggers Cracker but then starts to decay just as fast while accelerating?
What am I missing here? The Follower airflow is present so the TPS is registering? And that is what has me so confused. The Follower air is there and yet the Cracker air starts to diminish all while Accelerating and above the 12mph qualifier?
Thanks for the look.
