After weeks of reading, learning and logging I need to understand if my thinking makes sense.
I started by dialing in the maf using the trims and got things in line. I read that doing it with the AFR error on the wideband is better so I redid it that way. When I get the error down to +-2 everywhere, the trims are not in line anymore when I turn them back on.
I'm thinking that if the O2's are looking for 14.7 by default, but my commanded is 14.40, then the trims and afr error can never really line up. By tuning with the wideband afr error (with the trims off) I am basically getting the afr to 14.40 everywhere. If the trims want 14.7 then they cannot match.
If this is correct, what is better, to tune to 14.4 with the afr error, or use the narrowbands to 4000 rpm and the wideband error for higher and PE ??
Thanks for any input as this is driving me crazy.
