emissions and reducing HCO

Re: emissions and reducing HCO

hmm, why would the spark be weak at idle, but be perfect at cruise?

Same with the Cat? the car is stupidly clean at cruise...

Big cams don't like to idle. The hotter spark helps clean it up.

Not possible considering the ICM and PCM are controlling only three coils. You need to find a way to control 6, and you're going to need more than just an MSD DIS-4. Wouldn't see the point unless you're building something insane....

Exactly what i was gonna say.

hotter being lower spark timing then? or more spark timing?

hotter spark being more spark energy, hence the MSD ignition.

Re: emissions and reducing HCO

Im going to bump this thread. What do you guys know about acetone and denatured alchol?

They just recently changed our emissions for 2013 and all 98+ vehicles get the OBD2 test, while I get shafted and have to do a 2 speed idle test.

Last time I could do a "deal", now they have changed the setup so that they are filming/taking pictures of the whole process...Not sure if I can get this thing on the road unless I figure out a way to clean up the idle some.

The test now only checks HC and CO, not NOX anymore, which is good I guess. Looks like from my post 2 years ago on here that I was high in HC, don't know where my CO sat at.

Whose an expert at passing these things? I am going to bump my spark way up as suggested much earlier (didnt do that last time)

But I want to hear more about denatured alchol/methyl hydrate

Re: emissions and reducing HCO

I would bump your idle up to 1000 rpms and see how it does.

Re: emissions and reducing HCO

I had bumped up to 1200 for the test, I regularly sit at about 1000, anything less and the car isn't very happy

When did they change this?? Taking pictures of the process? Either where I take it fudges the whole thing or I didn't hear about drastic changes...

January 2013 new emissions tests/standards have been implemented. You could get away with fudging prior to.

They don't tell you that they film it on their website, but I have been talking to my sources and there is a discussion in the canadian section on ls1tech regarding it. It is going to be extremely tough to fudge the test.

The test doesn't need to be "filmed" I don't believe, it's actually a series of pictures (clarifying what I said earlier) but they have to be of the front/back/side/dashboard of the vehicle.

Thank God I still plate my vehicles in Indiana.
