Here in Utah we have diesel emissions (I believe isn't a standard yet nationwide). My question is, if I were to go with injectors and a dp chip would a stock setting be clean enough?

Another thought is that they could make a custom burn just for emissions. Here in UT they plan on getting tougher emissions in the near future according to the tech who did last inspection.

I know the man to talk to would be Jody and I plan on calling just thought I would throw this out.

 

how extreme do you want to go on the injectors? i bet jody could work a specific setting or something that would fire each cylinder every other time once it got above a certain RPM but kept a smooth idle. i think that would be the only way around it, because im sure any aftermarket injector will put you over the limit, im almost certain of that.

 

So just shop for and pick another state to register your vehicles in. There are lots of advantages to picking the correct state. Sales tax, inspections, emmisions, and for me the big one is insurance. I went from a state that I was paying $520.00, now down to $181.00 for the exact same coverage. One way to shut these socialist thinking communities down is just to boycott them.

 

Here in Washington, try that they come after you with big fines. I had a conversation with one of the air quality officials on that subject because I know a few people that register thier vehicles in a non testing county.
They check how you paid for the license tabs, if it's paid for with a check that is registered in a county where they do testing then they assume you are cheating and come after you. You have to be very careful of the paper trail that you leave.

 

i would say anything stage 2's or under and the smoke can be controlled with tuning. Any other large injector especially with large nozzles is gonna be hard to tune the smoke out of.

Oh boy. Y'all have no imagination, tell 'em you live in your motor home, a month here, a month there and so on. You just hide from crummy weather (not foolish taxes) then ya ask 'em ' what's a fella supposed to do? They are Gov. employee's and can't come up with an answer to that one.

 

easy just pull the chip off when you go to get tested. you will be fine. no chip no more fuel than before

 

Not so with bigger injectors, though, which is what the OP is considering.

You'd probably have to detune below stock, depending on the injectors, or they'll still smoke.

 

hhhmmmm i have bigger injectors

pulse width.. i could be wrong though.


with bio and my fuel 7 setting it hardly smokes.

so i would think if you ran no chip and bio for test you would be great.


is the utah test done on rollers or parked?

 

i know w/o a chip my truck smokes like a truck w/ stage 1's and hot chip.... It will not pass emissions that way. detuned below stock would be the only way to get by emissions.

 

if the injectors have stock nozzles on them they wont smoke more than stock.

you have to have the timing and pulse width to get the extra fuel out of the injectors that they are capable of delivering.

the bio d helps with the smoke too, svo smokes less also.

 

The test here in UT is done on rollers. Pretty cool to watch and see the tech's, my truck gets squirely on the rollers(they just chalk front tires and really gave me a scare the first time). Right after my last post here my video card crapped out so I haven't been following up. I will call dp-tuner tomorrow and will post what I find out. It would make my day if they could get a set of stage II's to work with a tune.

 

I'm sure Jody can figure out how to tune your truck for emissions. I have the DP-Tuner running 40, 80, and 120 tunes. I passed emissions here in Colorado on the 40hp setting, and ran better emissions numbers than many of the stock trucks they were testing. Jody is Da Man!

 

Just got off the phone with Jody and he said he has done it atleast twice for OBS trucks. According to him he tunes the chip below stock spec's to compensate for the added fuel. Sounds like there isn't much he can't do.

Now have to add injectors to the list of things to do.
