Passed Smog, how do I interpret these results?
Just curious, how do I interpret these results? I passed smog, but is my car running to lean?
I have a Steve W. chip and no mufflers on the car.
15 mph
NO = 0
CO = .01
HC = 21
O2% = 0
CO2% = 14.7
25 mph
NO = 0
CO = .04
HC = 31
O2% = 0
CO2% = 14.7

Those are decent post-cat values.
The only way you'd know if it was truly lean would be to run the car on a dyno and sample the pre-cat exhaust stream with a wide-band sensor.
