SG can do AFR accurately on unaltered o2s signals.
My Elantra have 2 o2s, and the factory pre cat one is a wide band. Your Yaris being a very recent car, it might have one too.
I get the AFR in an XGauge with the following:
TXD:07E00124
RXF:044145240000
RXD:2810
MTH:05BE80120000
SG can do a lot more than we think.
