Default Can a maft adjust one bank at a time?

I was running rich on both banks (.92) after my headers. I was going to get a maft, but I decided to swap back my ported factory maf ends for my Whisper ends. Now, B1S1 is good at .91, but B1S2 is lean at .86-.88. Can I adjust this one bank with a maft? I don't want to mess with B1S1.

50mV is not a big difference, this could be
from mixture or just from electrical
variation between two sensors. Especially
as you get further from 0.5V, the response
tends to "saturate" and you can't say that
0.92V means any particular AFR; only that
0.92 is richer than 0.90 -on the same sensor-.
Might try swapping them side for side and see
if the readings move with the sensor. If not,
then it's mixture most likely. If yes, might
want a fresh pair (new should match better,
especially if from same mfg batch).

Thanks for the answers, but doh, I screwed up. I was monitoring B1S2 instead of B2S1. Just did a shakedown run and both banks are at .90-.91. Looks like the Whisper ends leaned me out just enough. Need no tuning after headers <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
