Need to check with the manager of the place. Down in tucson its just push it and let go no need to hold so a quick throttle blip is basically it.
All they are looking for is SMOKE and nothing else. They get all the readings they need off the computer and from the tail pipe probe. Mine has 11% or less on the test but it does not get run a lot either so I have to take it out on a run 1st. R floor it and then let it off. Ask to see the procedure they are to follow, but since you ar eup in east LA there is no telling what is going on.
Actually they are looking for heat as well. If you don't push it hard enough to make enough heat it wont even go on to check the opacity. After a certain number of failed attempts, it fails the test.
I will estimate that they probably only had me hold hard throttle no more than a second or second and a half each of the three times in succession. I only did 3/4 throttle, not 100% as they asked, but that was quite enough for the governor to kick in.
Per my emissions result read-out, my Cummins tested with 8% opacity.
