That's a good point, I wonder if there is some standard for that. He might just have a dumb tech.

Same guy every time?

Two different places. The second and third time were the same person. He used second gear for the 15mph test and third gear for the 25 mph test. He was shifting at the right time.

Hmmm, I dont know the gearing on those Jeeps but that sounds like it should be 15 in 1st and 25 in 2nd. Just because its in a higher rpm doesnt mean he has to shift. 3-3500rpm will be a lot lower NOx still than 1500rpm at that speed. You know what the rpms are when he does the test?

When the dyno starts a vehicle with a man trans, the computer prompts the tech to do the test in second gear. The machine has speed and RPM limits during the test.

1752 rpm @ 15mph
2764 rpm @ 25mph
Even on his 25mph test @ 2700rpm the nox was on the high side. 600 parts per million, passing spec is 780 .

Why not take it to "another" smog shop?

Shady guys won't do it if you've already failed a time or two. They don't want it to be suspicious.

I passed! The combination of 27" tires and wrapping the Cat in tin foil to get it really hot did the trick. Thanks for all the help.

Your mom's hot.

I remember we were staying over at your house late one night when we were like 16, and your mom came out to give us a ride somewhere, and she was just out of bed with her hair messed up in a night gown... and you said "Nice hair mom" She said "Thank you Steven" sarcastically, "Nice dress mom" ..."Thank you Steven" ..."Nice butt" ..."Steven!"
