I know O2's aren't the best way to monitor A/F ratio, but does anyone know O2s voltages for APPROXIMATELY 14.7 cruising? I don't have a wideband and will not buy one so I was always wondering how good my highway tuning was.

Under most normal circumstances, fuel trims will be locked in PE mode and will not effect fuel management.
