Catalytic converters

In CO they test on a Dyno and run the vehicle on a program. The tester has to keep the vehicle speed on a line that moves up and down. I assume it is simulating the real world. The first time the tester did it he kept hitting the brake to maintain the speed. I imagine an untalented tester could make the test fail just by how he keeps the speed on the line.

It is getting pathetic.

Colorado the new California
Same **** here, the tester put my Mazda in first gear and then accelerated to 15 MPH watching the line (must keep it between the lines here) . The machine recorded a certain RPM and a big red flag went up. The tester stopped the test and told me he had to abort the test and he could not continue on this car because the RPM's exceeded the test protocol at 15 mph. I told him shift the F'n thing into 2nd! (I think I used those exact words) He told me the test must be carried out in L or first gear. I told him the friggin rear end dictates the speed at a certain RPM in 1 gear and there is no way to FIX that. He told me he could not continue and don't bring it back. SOo...Smog referee wrote me a note telling the next joker than you CAN test in 2nd gear IF the gearing prevents X RPM's to roll at Y MPH. What a F'n waste of time. I told this story to another guy 'in the know' and he said the station was probably on probation and they were walking on thin ice already. Then it failed (in 2nd) because the fuel pump was bad and it leaned out holding 25MPH under the roller load. That truck was cursed back then!

CA cats: They are the SAME cats but if they carry the CARB stamp or suffix, they have to be warranted for 100,000 miles, not 30K like the old "49 state" value. So its just the warranty you are buying for 3X the price with the CARB stamp on them.
