AFR Meter and LTFT Log

[aggie88]

I am trying to adjust my tune based on the LTFT logs (2005 Corvete U7191). The LTFT Bank 1 reading is around 3.9% and the LTFT Bank 2 reading is 1.5 %.

I happen to have a narrow band AFR meter tapped into the drivers side O2 sensor. Some say that the resistance of the AFR affects the O2 sensor reading. Does anyone know if this is true?

Yes, this can happen, plus, that narrow band A/F thingy dont work anyhow (well, it should be good at showing you stoich, but not much else), better off disabling it, at least while logging...
