Though the standard for 17 year old cars isn't very high, my car passed with a HUGE margin. Goes to show that regardless of how a car is modified for performance, if it meets the emissions standard set for the same car unmodified, it should be legal. This was all Link auto tuning - first coarse, then some fine.

 

Until you put cams in... lol

 

it already has cams... won't run without them

 

Bahhh

Till you put high lift lopey idle cams that come on at 120000000 rpms!

 

So when do you want to help me learn the PLink so I can pass too?
(Haven't really had the chance to dive into it since I got it installed)

 

I'm assuming you actually do have a cat in place?

I have to get through emissions before the end of the month. Considering putting the CatCo cat back on vs trying to get through it with the test pipe.

What pisses me off is that no one 1/8 a mile from me in a 270deg arc has emissions. I am *just* in the county line, which appears to be amazingly jerrymandered.

 

Might as well get ready to have a car that will pass no matter what though. A salesman here also co-owns an emissions shop and says that the requirements are about to be statewide anyway.

 

You would have failed in California, IIRC.

 

I car that passes emissions is well tuned car IMO. For our sake, what we really care about is making power in boost and that's not tested. You could in fact run leaner out of boost and get better mpg - and you might fail. The real issue for power is the cat. It's not an issue for me (I'm eco-centric ) but there are high flow cats out there - cha-ching. I'm running a 3" universal from ebay that was under $40 delivered.

Ben I have an old cat shell that you could split and tack on both sides of your exhaust pipe to sandwhich the shell around it. :gay:

RotorNut - I think I could school you pLink in about an hour. I'm around all weekend if you're up for the road trip- or traveling thru. For tuning boost you will need something to viewe datalogs- DLL has a 30 day trial. - rob

 

Where exactly are you related to Atlanta? Driving doesn't bother me.
Won't be this weekend though, my b-day is Sunday.

 

My b-day is tomorrow.
I'm in Decatur - 5 miles east of downtown ATL. Shoot me a pm/email and we'll sort something out. Once you're "learned" you have to post up a tutorial for all the pLink converts.

But Sav- I would have passed in India.
I was rich, no doubt pulling 3 pts of master fuel would make me CA legal on the snif... of course everything else is a no-go.

 

Happy Bday in advance M2cupcar

 

Well Happy Birthday to you too!
Oh, you aren't far away then. Closer than other people I've gone to meet up with! But yeah, we can work something out, that is, if I'm still alive. I decided that this year was a good time to jump out of a perfectly good airplane from 3 miles up. lol

 

Happy birthday Rob. Kind of skin of your teeth with the emissions there buddy.
I'm not worried about the visual check. It's don't ask/don't tell. But I have to get through the sniff test.

Eric, I think you'll be closer to 2 miles up than 3.

 

Nope. 15,850 feet over Thomaston/Upson County. Nails 3 miles perfectly.

Now the weather just has to hold out like they say it's going to.

 

cool, highest I went was 12,000, and it cost a little extra. standard was 10,000.

 

Thanks guys.
Weather should at least be cooler "up there".

I didn't think it was that close of a pass- I just looked at a sheet from 02 for a 95 626 v6 and I would have passed that with a big margin too. That's five years ago on a car that was five years newer.

Here's some history (25/25) of my 90 for comparison-

2002, supercharged 1.6 with AFPR running pig rich


2003, Link ECU leaned out (better tune) from 2002

 

That's odd...

So the car running rich had signs of high NOx, indicative of hot combustion (running lean)? And the car running lean showed a higher HC count, indicating a richer mixture...hmmm

Not sure what happened between those years.

 

Would "hot combustion" and high egt produce similar results?

If so- then rich (excessive fuel) can lead to unburnt fuel escaping the cylinder post power stroke and completing burn in the head post valve and exhaust manifold. That would definitely raise EGTs.

 

Maybe, but I'd think in that scenario there would be higher HC count
