97' LS1 Unknown source of EGR advance - at least for me
Hi everyone, I am struggling to find where the heck this EGR advance is coming from.
You can see the video here.
I checked the EGR advance table and it is obviously zeroed by default.
There is no wide band o2 attached physically to the corresponding PCM pin.
How I can find which table is triggering this advance?
Btw, I forgot to tell you that I forced CL, and I am trying to understand why the trims are maxed out during the learning.
Anyway, even without the forced CL, this advance is presented.
