I have heard a lot of discussion on O2's and the equivilent AFR. I bought a wideband and It reads 11.70's under WOT. The O2's are 890 to 910 at these same ranges. I just want to see if this sounds right. I just dont want to pin all my tuning on a wideband that is giving me less than acurate readings. How would I know if they are off??

 

Almost any brand of wideband will give you more accurate data than you can get from trying to read millivolts of of a narrowband o2 sensor. If you want the most accurate data, get a wideband that can re-calibrate itself in free air.
