OBD2 and A/F

Can you read the A/F ratio via the OBD2 port by for example using the predator data logging feature? or do you need additional sensors?

You needa wide band, controller and some way to read it. Stock 02's aren't accurate enough for proper tuning.

+1 a wideband oxygen sensor and a gauge, box, handheld, or whatever to get a reading.
