1990 Acura Integra • 4 cylinder FWD Automatic • 182,000 miles

Here are the before after results: Both passed, the after with much better results.

Before 8-23-10 odometer 179,375 miles

CO2 O2 HC CO NO

15 mph 14 0.1 85 .37 739
25 mph 14.9 0.0 31 .11 126


X device installed at about 182,200 miles, drove only 400 miles.

How significant is this? I think it merits more research. It could be the magic bullet.

Interesting how the Co2 numbers came down and the O2 went up.

After calculating Lambda, the before numbers showed a Lambda of.9917 which is within the fuel control range of the O2 sensor and and air/fuel ratio of 14.58
After shows a Lambda of 1.137 and and air/fuel ratio of 16.71 which is a lean mixture. The STFT and LTFT numbers might be worth looking at before you try to load that magic bullet in your gun.
