i calibrated the wideband sensor programmed it using the programmer and on megatune it keeps reading either 10.57 or 19.96 at idle. Im pretty sure somethings not right.

I have the same issue. I have soldered all ground wires and still the same thing. It does start working evry now and then without reason but then goes back to this same state. All grounds are soldered to a 10 ga wire in separate locations. The wire is ran to the block. I recalibrated once and it worked for a while then it went back to doing the same thing. I am running the 12v power source on a toggle switch rather than a switched 12v souce.

same here, sensor recalibration did nothing for me and im running power from the igniton wire, chassis ground. It sucks because i cant drive my car unless i have an accurate afr. No afr= No tuning.

my wideband o2 sensor is about 6-8 inches away from the front o2 sensor. I just tried different ground and still the same thing. It reads a constant 19.97afr no matter if i rev it or let it idle. When i open logworks the gauge display on there says 30.8 and fluctuates between 30-33 afr

i just regrounded it to my MS ground and the afr readings are the same still. How do i fix this (besides using a toggle)? Which setting do you have in your megatune configurator?
