Emission testing question

[retirednak]

Fellas,

I'm thinking of moving to the Green Valley AZ area,does anyone know if I will have to worry bout emission testing on my truck? My truck never came with a cat on it and shorty after buying it I added the 5"turbo back exhaust. Before I make the long drive,I may install new injectors with the 50-60 hp tips. Will I have any issues? I will for sure back my Smarty settings to 1 or go with the stock tune. If they do test in that area,what kind of testing is done?

Thank you!

Put your Smarty at the stock HP level for sure. I'm not sure about the tips but our trucks pass so easily that I doubt it would be a problem.

You should be fine, but SW1 TM1 TQ1 RP1 and PoD 50 should ensure you puff no smoke. Just make sure you can get to 2500 rpms in N before you take it in.

Your best bet is call the DMV and ask what their emissions rules are. That way you have the the info directly from the source.





A lot of places don't test diesels over 9k GVW. Not sure if your truck falls in that category but the DMV would know.



They would also know what test they actually do so you can tell if it will pass. Turn it down with the Smarty and you should be good.

I don't think Arizona test outside the metro areas???

Thanks fellas,its going to be hard dealing with the emissions folks since I haven't had to deal with emissions testing even in my gas powered vehicles in over 33 yrs here in Alaska. I checked out the ADEQ website and found this in... ... ..... Diesel emissions testing in Pima County and for light-duty (8,500 lbs GVW and less) vehicles in Maricopa County consists of loading the vehicle on a dynamometer and measuring the opacity of the exhaust plume. The measured opacity must not exceed the established maximum. In Pima County the maximum allowable is 30 percent opacity. In Maricopa County the maximum allowable is 20 percent opacity. (The maximum allowable is determined by the average elevation of the registration area). Heavy-duty (8,501 lbs and greater) diesel vehicles in Maricopa County are tested using the Society of Automotive Engineers J1667 test protocol, commonly referred to as the "snap-acceleration test. "

You'll be okay. There is no emission testing in Arizona for an 03.

When I use to work for Caterpillar, you had to go through Green Valley, AZ to get to the testing grounds for Caterpillar equipment. This was off Duvall Mine road. The only thing you need to worry about is the golf carts and restaurants closing at 5:00 PM in the evening.

I have attached the SEMA web sit for emission testing by states. Gas vehicles are listed first than diesel vehicles, for your use.

I just tested my 2500 in Phoenix, Maricopa count. Limit on opacity was 40, mine tested a 10. No issues other than, having to rev it up. 4 times on snap test. 3575 rpm's is hard on my heart.

They made you rev it to 3575? I would tell them to kiss my #@$%!... There is no way they can require you to rev beyond redline!

 

[K3RACE]

You have to put it to the floor for a second or two then let it snap back. You have to do it three time following a prompt on the screen. Yes I was shocked when it went to 3600, but the process was in play so I finished the game. I think with the commonrail flooring it in park there is no way the system can shut down before redline so it keeps going. Next year I will experiment with something under pedal and see if I can keep it closer to 3200. We are a long ways from a governor and mechanical pump.

 

[AH64ID]

I guess I would get into a large heated argument then. . no way I am putting the pedal to the floor in N or P (if I had P). The ECM will allow 3500 in N, but I don't like to run them that hard!



EDIT: So I know I had read about maximum overspeed limits and went back and found them. Cummins rates the valve-train for 4200 for 15 seconds... Still not sure that emissions can require me to go past the redline thou.

I totally agree with what you are saying but I was not prepared for it reving that high. The problem is you either do it or you don't pass. I am not sure you can do this and hold it at 3200, idle back, 3 times as prompted. I am sure everyone in Phoenix woth a commonrail would like to avoid this. Just asking for a problem.

 

[Prairie Dog]

I just rev mine up to 2500~2700 or so and that generates enough heat to allow the system to measure emissions. Surprisingly or trucks will rev way higher than 3200 if you plant your foot in it.

 

[steved]

It might show it on the tach, but is it actually spinning that fast?

 

[AH64ID]

I would say yes, why would the tach read higher?

 

[steved]

The rest of the gauges are fake... ... ... ... .

:-laf so you think the tac is only accurate below redline?

I totally agree with you. I won't rev my engine that high. I'd just up and leave. Screw um!

No, I doubt its accuracy period...
