I FAILED emissions...horribly

[stumiister]

The law in Crapafornia is any diesel older than 1997 does not need emissons testing.But I think there may be a certain weight class for the rule also.
Im glad they dont smoke test the older diesels here in Crapafornia, that was the whole reason I got my IDI, also I have a 5'er to take camping sometimes. But I'm sure it is coming in the future.When doomsday finally does come all these new computer controlled diesels will be dead on the road and our mechanical trucks will be running and burning just about anything.

Best solution is to move out of the SLC/Utah Valley area.

I just received my Smoke Puff Limiter, but I did not recieve instructions in the box. There is only the limiter and a sales receipt. I contacted Hypermax and they said they would try to email me a copy...

Does anyone have a set of instructions to post up or a step by step, how-to?
Thanks!

I'm pretty sure it is swapping one IP cover for the other but I haven't found detailed installs online, any help is much appreciated.

Can't help you on the install but I can't wait to hear back on the results I may need one as well with Cache passing the emissions testing this year

 

[SLC97SR5]

RotBox, you have a few options:
-Turn your fuel waayyy down
-Pull the airfilter
-Run kerosene
-Max out your boost
-Retard the timing to 5ish degrees

I would get a baseline opacity number before dropping any $$ or worrying too much. Don't sweat it, I have been down this road a few times.

I installed the Hypermax SPL today and it appears to work as advertised.

I passed!

Those that do not have emission testing don't know how good they have it.

After some adjusting and modifying, the Ford belted out a 2.2% out of 20%. That is a bit better than the previous 64%.

wow. that is awesome. all you changed was adding the SPL? did you do anything with timing or fuel as well?

 

[SLC97SR5]

No, was hoping the SPL would solve my problem all by itself but it did not.

Back in '92 when the SPL was designed, Hypermax never accounted for a hot IP/Turbo setup. They set the aneroid wafer up with a 5psi full fuel threshold regardless of setting. What does this mean? Well, as soon as 5psi is achieved you have full fuel available. In stock form this would be just fine but with a Moose pump, I'm now trying to burn 90cc+ of fuel with 5psi. Not good.

So I conditioned the signal from the boost reference line on the Turbo to the SPL.

Umm at 5psi even a moose pump wont smoke... something else is going on (and Im at simmilar altitude with simmilar fuel output)

You are saying that at max fuel, pedal to the floor from a standing start that your pump will not smoke @ 5psi?

Wow, even my stock calibration would smoke when lugging it @ 5 pounds.

I am not sold on BB injectors being the best. I'm thinking of having my Turbo G codes re-popped and shimmed.

 

[kc0stp]

From a standing start Ill smoke untill 5-10mph, anything faster and it has to be really lugging to get smoke and the auto will downshift before then rough looks at the boost gauge puts it at 2-3psi when the smoke from a stop ends. In park/neutral I can turn whatevers next to the truck black as night though

So I conditioned the signal from the boost reference line on the Turbo to the SPL.

What exactly did you do? The easy thing would seem to be pull the line off so that you never reach full fuel (its always reading no boost) It would probably run like crap but would certainly cut the fuel down. Curious because I may have to go through this hurdle when I get my truck on the road.

 

[SLC97SR5]

Woohoo! Another sucessful emission test, god bless the Hypermax SPL!

well, that knocks 1 state off of my "to move to" list...
no way am i going to have to deal with stricter testing laws than commiefornia.

It is a county regulation, not state. We have enough California idiots as is.
