Default Does EMB datalog A/F ratio?
Two questions,
Can the EMB datalog A/F ratio from a wideband?
Is it possible to use olderguy's autotune for EMB with a wideband O2 sensor?

You can use TPS input to datalog WBO2 voltage.
But you need to convert voltage to AFR.

EMBs Autotune Olderguy can answer best.

You can also wire a W/B into the boost port and this way it reads A/F ratio as real numbers.

But means you need to hack a MAP signal into the throttle position wire and use that as your vertical axis
