Link ecu:narrow band a/f gauge and link wideband a/f #s don't match and missfire?
I have an LC1 plugged into my 1.6L link and a heated 3 wire narrow band(N/B) supplying signal to 20 LED rich/lean gauge
I was told that a # around 76-78 on the link fuel count indicates stoic and last summer this showed true when compared to the N/B gauge.
The problem I have now is that there is no correlation between the 2 gauges at all and have what feels like a lean cruize miss.On cruize I get any where from 69-84 on the link display and usually off the screen lean on the N/B.Under boost the link MAY jump up to 84 and the N/B is wherever it wants to be at the time.No noticable exhaust leaks.No fault code flashes for the LC1
Both O2 sensors were replaced last summer and I recently did a free air calibration on the LC1
Any suggestions where to start?
edit:I did replace my battery a month ago?

Jeez, OP. I'd hook that LC1 to the display and forget the narrow band all together. This only if you are running the Link standalone. Then you'll have something to work with/talk about. Does the Link really not display real AFR in datalogging? Are you running the Link standalone? Are you using bandaids?
