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.

After 1-19-11 odometer 182,619

15mph 12.9 2.7 17 .09 396
25mph 12.7 3.1 7 .01 146


Basically, shows across the board improvement only NO at 25 mph a little increase.


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.
