You keep asserting that, but it hasn't been substantiated.
Here, since you dropped $20, I'll put the data in a table to make it easier. It would be better with more tests and control tests, but this is it for now.
Code:
Test RPM %CO2 %O2 %HC %CO %NO mph hp torque
1 1735 14.8 0.0 62 0.06 101
1 2800 14.6 0.3 16 0.02 89
2 1698 11.8 4.4 39 0.02 105
2 2752 11.4 4.9 14 0.01 74
3 11.7 4.5 2 0.0 75 6.1 5.3 117.4
3 12.1 3.8 6 0.0 544 7.8 6.7 116
3 12.1 4.2 11 0.1 195 9.8 8.6 117.5
3 12.3 3.4 3 0.0 76 14.6 12.8 117.3
3 12.5 3.1 1 0.0 71 14.9 13.0 117.3
3 12.2 3.3 1 0.0 90 20.6 10.9 70.9
3 12.3 3.5 0 0.0 78 25.0 13.1 70.2
Observations.
1. todays tests don't look like they have enough resolution for %CO
2. I don't know what scaling they use for %HC in test 3 but it varies a lot percentage wise. Is it apples to apples with the previous HC measurements even?!?
3. The readings at 117 ft/lbs are probably 1st gear
4. The readings at 70ish ft/lbs are probably second gear?
5. what happened to NO% at 7.8 mph?!?
6. CO2 has settled on a value between the 1st test and the second?
7. %O2 has also settled on a value between the 1st and second test?
What is the theory on the cat? Gasoline is pretty volatile, I don't know why you think it takes 800 miles to "clean" it, or why C02 is higher than test 2?
