MTX-L connected to TinyIOX gives wrong reading
 

I've connected my MTX-L through the TinyIOX and although all seems to be set OK, I'm getting wrong values for my AFR.
When I'm connecting the MTX-L to the analog O2 port as usual, the values are correct.
Is this a setting that I have wrong somewhere? My TinyIOX reported AFR is 14.3 (green on the laptop) while the gauge is showing the real AFR of 16.4
The gauge does correspond to the laptop, ie it goes up and down together with the reading on the laptop.

Are your afr data settings correct? See this big post I made on setting up the tiny.

Turns out for some reason I had stoichiometric AFR under General Settings set to 12.7. Putting it back to 14.7 solved the problem.
