Just got my car smogged. I tweaked it a bit to ensure that I would pass. Pretty good for a guy still learning drivability. Thoughts? Check out the readings.

15mph:
CO2: 15.5%
O2: 0.2%
HC: 51ppm
CO: 0.06%
NOx: 782ppm <--cold cat! :hammer:

25mph:
CO2: 15.5%
O2: 0.0%
HC: 17ppm
CO: 0.02%
NOx: 73ppm <--told you guys it was a cold cat.

Honestly, this is unusual. I've never seen CO2 above 14.8% How the heck did I get 15.5%? What's up Ritz? You smog cars every day, what do you think? Westborough?

My mechanic friends are all
