    Yes, just gradually increase the lower temperature cells of {A0008} until you get consistent AFR as it warms up. That table should end up as a downward slope as temps increase.

    Default Afr fluctuations with olsd

    Ok so this thing is still doing it. I have been doing some reading on other sites and some guys running way bigger injectors than me are having no issues maintaining idle using hp tuners. They recommend lowering the min transient fuel table but it doesnt look like we have that table and to change the injector timing with the spread sheet. I read the sticky on b3702 table but not sure exactly what to do there. Can one of you guys point me in the right direction?

    Can i attempt to run closed loop off of one o2 sensor? My one manifold has a bung in it still and i can swipe an o2 sensor off of one of my spare engines.

    No, CL requires both front O2 sensors.

    The minimum transient fuel table is B9021. They have it labelled and scaled incorrectly.
