The War On Imports...collateral Damage

[fletch63]

Hi all,

Just wondering if anyone can help me with advice

Got yellowed

Middle of the night on the FWY (doing 95kmh) for tint too dark (WTF!!)

Now after 3 pit inspections and thousands of dollars later I have been asked for an emissions test which I did today

My car has stock turbo and ECU and engine is stock. New exhaust from Kermit (pits didn't like my old one)

The guy at the place I got emission test didn't know if it would pass or not but said it was too rich so possibly not.

So, my question is...does anyone know how to help lean my 33 GTST out other than ECU replacement/upgrade and tune.

As they didn't lift my bonnet I was thinking remove the pod filter. Would that help??

Also any fuel additive anyone could suggest.

I am almost at the point of giving up and parting it out.

No-one would believe my story so far with dealing with the pits. I can't believe it ...am totally over it

Maybe time to surrender in this "war on imports" and go and buy a hyundai excel

Any help would be greatly appreciated as I would probably neck myself after driving an Excel for a month.

Would think a decent cat and exhaust should cut out most of the emissions problems. Might be an excuse to get a new ECU and tune it anyway if it's running too rich. Removing the pod filter and putting on the original air box? AFAIK removing all filters is bad (for obvious reasons) and most are barely restrictive anyway so fiddling with it is unlikely to benefit.

however.........restricting air flow might cause the ECU to complain and retard ignition although that might just reduce power output rather than run it leaner???

I would only take the filter off for the test and then refit just after driving out

Just thought it would lean out the AFR but not sure

Maybe turn the CAS back to retard timing just for the test

Does anybody know for sure???

What about fuel additives also???

Is it running stock boost? With just an intake and catback.. you should be able to pass an emissions test. Just make sure you have a decent cat.

And instead of bringing it to the actual pits, lots of people bring them to certified workshops. A mate of mine brought his car he bought from over east to one in Myaree and they even offered to raise his car up for him so he'd pass!

Mate, may I ask which pits you have been dealing with? I just got a yellow for dark tint and would like to avoid the scumbags who have been giving you grief.

for stealth i would be getting a NISTUNE on the std ecu (you may be able to lean off the mixture slightly) as they MAY check to see if the factory ecu is there or not, using a registered workshop is a very good idea as the guys there would have a more positive attitude towards the car ie they want to help you

Leaning it out doesn't help. Needs to burn a bit rich to remove all the bad gasses. Getting a quality Euro spec cat would be your best bet.

This is half the reason I sold my gtr. I'm sitting in a bf typhoon now. Over 300 hp at the wheels and stock as a rock.

yes stock boost

probably too late to take it to a cert w'shop because they are on my case/arse now

will try a new cat if it fails

welshpool

dont go there

trust me

[fletch63]

Thanks guys for all your inputs

I will try a new cat if it fails

trouble is I have to wait 2-3 weeks to find out as they have put me to the bottom of the queue again

Any more ideas would be welcome

Does anyone think resetting ECU or removing pod filter (ie having no filter on just for the test) would help?

[Everlong-S13]

Damn I was about to go to Welshpool! Thanks!

Welshpool was fine for me on more than one occasion. Just depends if the inspector got lucky the night before.

[Everlong-S13]

Hmm well it is closest so I might have to risk it. Will go early in the morning first thing as they don't take bookings?

Running rich or lean wont reduce any of the nox in your exhaust (the biggest thing they chase on an emmisions test)

Only thing I know of, that will help, is to get the cat as hot as possible, as quickly as possible. Best way to do this, is to get the cat fitted as close to the turbo as physically possible.

Pretty sure leaning it right out will actually increase some of your emmisions, so be careful with that.

And there is no way any reputable place would do an emissions test wit no air filter. Have you thought about putting the airbox back on, and slipping a K+N panel filetr in there? The arent the best filters on the market, but they def flow a buttload more volume than the std paper ones.

[fletch63]

Passed the emission test

Got the yellow off!!!!

I was worried for nothing about the emissions

Did take 4 pit inspections and 2 engineers reports tho, so I was pretty negative

Thanks guys for all your inputs
