Stock O2 Sensor
So last night I had my ebay BT OBDII reader hooked up to my android phone using torque and I noticed something. There are two different O2 sensor readings there: One is AFR requested (or something to that effect) and AFR Measured. The measured value behaves just like a wideband sensor. The AFR doesn't oscillate like a narrowband setup either. I saw it go as high as 20:1 and during normal cruising is would stay very close to 14.7 to 14.9 with small variations.
If I am correct, and the car is equipped with a factory wideband that would be fantastic! No need to buy / install external wideband for tuning purposes. Just log the factory sensor!
I'll make a graph later today to show you what I mean if necessary.
