Diesel (state) emissions testing Q's

[JBakerFX4]

Just a shot in the dark here but on a regular gas car they hook it up to a exhaust anylazer in some states to get your decal. Heres the question... Is there even such a device they use to test diesels??? Out of all the states out there... even in Cali, how do they test these trucks? Visual to see you have a cat, or do they actually put you on a dyno with a exhaust sniffer?

cali there is no test for diesels =P

[SuperCrutyPS]

^^^ Yet....but there are rumors that Cali is considering it....It may start with '08s and newer because of the DPF. But ya gotta know, if it starts at all, it will eventually get to all diesel powered vehicles. it will help bring in more $$$$$$$$

[JBakerFX4]

What I'm saying is, for the states that do have emissions testing for diesels, what do they look for?? b/c let's face it, if the EGR system is gone... how are they going to know? Same for the cat. unless they look, or use a sniffer. and the same goes for a SCT. Or do they hook the PCM up to a scanner also?

[dayusex]

I dont know about how they would do it now


As for California, there is no way they can require older vehicles to purchase DPF filters so they pass. What are they going to do, buy us all DPF filters??

In mass i am a vehicle inspector and here diesels with GVW over 10k need to get a snap test is where we put a probe in the exhaust and we rev the engine and then idle rev then idle and it measures the particulate. the standards arent very high. on the light duty diesels personally i dont care if there is a cat or not on it. when i was taking the training the teacher said to use your own judgement where as to fail a ricer with a fartcan exhaust rather than a big v8 that sounds good. i know in Rhode Island nothing over 8600 gvw gets tested

[jblagg]

not in tx either

[JBakerFX4]

so F250's in Cali, Rhode Island and TX don't get tested. NICE. I've just been paranoid if I have to move from FL to say GA, AL, TN, VA or any other state and I have a full EGR delete and no cat my truck won't get a decal. trying not to screw myself. But if what you guys say is true, I'm good to go. So the only thing standing inbetween a SCT, full EGR delete is ARP studs and my 10yr/100k warranty.

They use the obd2 port on gas vehicles here. They don't sniff test them anymore. No test on anything with gvw over #8200. Don't currently test diesels.

you dont need a full EGR delete..your truck is too new..with too much warranty left..

block off the up pipe..get the SCT (custom) and have the EGR valve disabled..and you should be good to go.

A full EGR delete is really for people who are out of warranty..or who are making more then 475 HP at the wheels.
