Low Idle Afr Nytro

Make sure you are using the proper sensor. And make sure it is not a china knock off. I have had issues with knock off ones.
 
I have a 2016 SR VIPER turbo RTX with an AEM AFR gauge and it's reading --- on idle. I lowered my gem controller to #1 on idle from #4 and gauge still reads --- on idle. Anyone have any ideas on why I'm getting this reading?

Did it ever read correctly?
 
It did read numbers on the gauge before. It didn't always read --- on my gauge. It idles fine, I cleaned the end of my sensor in the exhaust but still reading ---

Could be bad connection. Usually when o2 fails it shows full lean or higher numbers. But if you run race gas, it will take out 02 sensors faster.
 
I am going to do a few test runs a see my numbers. It only reads --- on idle. Gives numbers once I give it throttle.

Oh that’s strange. Does it have a range that needs to be set. Sometimes some gauges will only read so fat like 10 before it does that unless you can lower a setting.
 
Ya it's idling fine. My engagement, midrange, and under boost is reading what mpi says it should. Strange that my idle is the only reading that's messed up.
 
I wonder if anything below 11 it shows - - -

You could search that model see what it says in manual.
 
When I turn the key on it shows 14 then drops slowly to around 12 then it goes all the way to 17.9 (which is max on gauge) then ---. And the engine is not running yet. I start the engine and it still reads ---

Try powering it up after the sled is running.
 
If it goes to full max when 02 is usually shot but I have seen them fault out for. Ignition spikes and are fine if you power them after the machine is running.
