I know it is a Ford but it is 482 inches with a Comp 292R cam and a FAST system. This combo ran super well on the dyno but we don't have it in the car yet. I think it will run okay in the car but I'm pretty sure it will take some EFI tuning to get there.

I don't have the closed loop and learning at idle turned off, but do have all the air fuel ratio dialed in, along w/ the idle air control. It`s all part of the 2.0 system .
The learn at idle and at low speed light are pretty much constant , as I`ve kept creeping up on the tune. Pretty happy w/ it ,and think I`m close, "but ",was wondering if it will always keep the learning light on.
Thanks, I always appreciate ur input .
