96 Cobra, 2.1KB just recently added. Long tubes, EGR deleted. Idle sits with an idle flag of "RPM Lockout" and sits at 1.4 vmaf. Using Quarterhorse + BinaryEditor for flashing. A previous tuner had me flash via TunerPro RT and it had a higher idle set for datalogging purposes (reach stabilized engine temp faster) and it almost seems like it has persisted through tunes.
I have verified I don't have a vacuum leak. I've caused a vacuum leak and idle does not raise, vmaf still sits at 1.4v.
I have replaced my idle air control valve. No changes. Unplugging changes nothing vs plugged up.
I have changed a few idle / dashpot settings in the tune, unless I missed the one that would affect idling down, none of them changed the characteristics any.
I sit in open loop for dialing in fueling but I have forced closed loop just to see: same thing.
It drives me insane because it will go up to 2000 at first (RPM adders I've noticed) then drop down after however many seconds / reaches X temp, but always to 1600.
CDAN4/LLX3
If anyone has any wisdom I'd love to hear it because I'm about to lose my mind. Lol
