Self-tuning an SAFCII

Just to be clear:

I think what "Muzzy" is saying is that you can't read/monitor the A/F with an S-AFC and use it to tune with...

...and S-AFC is "Super Air Flow Converter". (EDIT: Not controller, sorry)

But...

You don't tune by duty cycle or changing ANYTHING directly related to the injectors...an AFC modifies the MAF output voltage that the ECU sees.

All it does is trick the ECU into thinking there is less or more airflow than there actually is...so the ECU injects less or more fuel.
