AFR erratic readings
I have a MSII version 3.0 running 2.25 on a Porsche 911 with ITB's. I have a PLX wideband O2 and I am getting two different readings in Megatune. When I first open Megatune and you get the screen with the 8 gauges I'll get a AFR reading on that screen of say 10.5 but when I go to the tuning tables and bring up the AFR table at the bottom of the page is a realtime readout in green that will say 13.9 at the same idle speed and temp what gives? I have calibrated the O2 as a Innovate 0-5 volt sensor many times but no change there is always this difference between the two screens. The car is running pretty good so I am assuming the 13.9 reading is the correct one but I want both of these screens to read the same or at least be close any suggestions?
