o2 mV = rich/lean
Ok quick question. I know this is a very crude way of doing it but in absence of a dyno or wideband will this work? When I had my z28 we logged with autotap the o2 mV.
770-810 = LEAN
810-860=14.7-1
870-910= RICH
I did some logging and at 5650 rpm Im running 900-910mV.
Can this example be used with the 350z?

Red, as you mentioned, this is a very inaccurate way to tune. All the narrowband O2 is telling you is if you are rich, lean, or stoich. It's useless for tuning. The "Rich" range is probably around 13.5:1 which is still exceedingly too lean for F/I.
There really us no substitute for wideband O2.
