have some o2 raeding questions Whats the differance between o2 millavolts vs. wideband readings? Reason i ask is because i see people using the gauge that tells you the millivolts and retard in one box. Or they use a wideband. Cant you tell your a/f with what millivolts the o2's are showing? Mine are between 940-960 at WOT. Bare with me guys as im just getting into this tuning part of it all.
This is on my '94 lt1 car also. But id assume a o2 is a o2.

the stock narrrowband O2 sensors aren't accurate at the WOT/PE levels, only at stoich 14.7 for normal cruise/driving.
But, if a wideband is not available, you can adjust your WOT/PE fueling to a "safe" range by getting the stock NB O2 sensors to read in the .88xx to .92xx range.
.940 to .960 sounds like you're probably running a little rich(er) than you need to at WOT.
