O2 sensor question
On obd-II cars there are two o2 sensors. I know that since they are not wide-band, they are not that accurate in the first place. However, what I wanted to know is which one is more accurate than the other, or do they have the same readings.
My plan right now is to go with the smc until Jan then switch to Hondata and I just want to have rough idea to what is going on with motor until then. I won't be going over 5.5 psi anyways so I think i will be safe until I get the Hondata and turn up the boost.

Re: O2 sensor question (willyboyD16)
The front one is used to control the air/fuel mixture. The rear one is just used to determine the effectiveness of the cat. I would use the readings from the front one.
