Wideband says I'm lean at steady state cruise. The gauge is reading 15:1 AFR or higher and I'm seeing the same with the analog input hooked up to the MVPI.
However, the STFT numbers are showing that the ECM is subtracting 15-20% fuel at the same steady state.
I replaced the wide band sensor since the original one is 6 or 7 years old now but nothing changed.
what am I missing?
