wide bands????
a side. The wideband O2 will swap into the rear O2 bungs
but its measurement may be corrupted by catalyst heat.
I would (did) just put one in the I-pipe; if the banks are
that different I reckon the narrowband fronts would
indicate that, and I don't plan on tuning the banks to
different values (the main params like MAF, VE, and
injector tables are not bank-distinct anyway; only the
stuff that pertains to the closed loop mixture trim,
seems like.
