Rich at idle

[shawnschuldt]

my car loads up on gas at idle and i read somewhere that there is a setting in hp tuners that controls the minimum pulse width, but i cant find it and my injectors wont go below 1.8ms

It's been a while since I've had the non-beta version, but it's under engine/fuel/ flow rate vs. kpa

What are your fuel trims looking like to be "loading up"?

all day yesterday anything below 1875 maf Hz would go straight to -16.4 but the rest of cruise was fine, and for the record i have 65# injectors.

but on the other hand it seems like it has worked what ever was wrong out, because the ltft are now back within normal ranges today

What does your idle on the wideband say though?

[shawnschuldt]

wideband reads normal right around 14.7

i take that back when after start wideband goes down to 10 which i dont thinks it reads below 10 and stays there for a period. Is there a table in ho tuners that adjusts startup fueling?

The car is supposed to run rich immediately after startup. It also has a decay table which brings it closer to stoich after a certain amount of time. I found when I messed with the startup AFR table, I had starting issues, especially when cold.
