I was reading this thread on a nissan truck forum:
I ordered the bluetooth OBD2 device. I will have to see if it works on the focus, it would be nice to have real data to see Air / Fuel Ratios, intake temperatures etc. Maybe I will pop the snorkle back on and run some testing too. This will take a while to gather any real data though.
You will only get useable AF ratio information if this car has a wideband O2 sensor.... which would be nice.
