I have a LC-1 Wideband O2 sensor installed which is feeding a dash gauge and MS2.
There is a discrepancy between the dash gauge and the gauge in TS.
For example, when the dash gauge is reading 14.7, the TS gauge says I m above 19…
I am inclined to trust what the dash gauge says but I would like them to match…
Thanks

Which setting for the EGO O2 sensor is selected in Configuration Settings?

It is set to single wide band and authority is set to 0%.
In the Calibrate AFR Table it is set to Innovative LC1 Default.

Re: O2 sensor reading in TS does not match dash gauge
Check the voltage you're getting from the LC-1; how much voltage are you getting when the MS is saying 19:1?
Are you using analog output 1 (yellow) or 2 (brown)?

Re: O2 sensor reading in TS does not match dash gauge
Your dash gauge is probably reading correctly. Your engine would have a hard time idling at 19:1 AFR.
As Matt suggested, check the wiring and voltage at the MS connector.
Measure on the CPU pin if you can.
I have the LC-1 with DB gauge. It works quite well when wired properly.
