failed emissions test.... grrr

[dyenerd]

ok, since the 680s went in, i knew my car was running somewhat rich. i got the car tuned so i could just drive it normally and wasnt worried since i was planning on not driving it until dyno/front mount/tuning....however my parents have been whining about the 2 months expired temp tag. so i decided to give it a whirl(on their dollar haha). i went w/ my bov vented(LONG aggrivating story, will be fixed tomorrow, DONT ask) and the crappy "tune" and well.... duh i failed.
my hc and co were very high, 9.something(llimt 2.5) and 32.something(limit 20). i attributed some of the failure to the vented bov, and knowing i was running rich. i have my afc settings all in the negative teens and its still running apparently way rich. does that seem right(frank jr 19c, stock maf, 680s)??????

also, the evaporative system failed.... wtf@ taht?! what all would i need to look at to fix that? charcoal can???

1) Running your BOV vented is almost guarenteed failed. + It's dumb and provdies no extra power.
2) Dont just turn your safc down for the heck of it. Use your logger to tune it and see why you are running rich, and where.
3) What FPR are you using on the 680's?
4) What pump?
5) Why are you still using a 1g maft on a 19c turbo?
6) Is your charcoal can still hooked up. I doubt this would have made you fail emissions, but who knows.
7) please tell me you have a logger.... Learn to tune the car, it's amazing how much power you can pick up if you know how to tune. I went from a 14.6 to a 13.5 on the 14b with just tuning and some race gas....

The vented bov is a HUGE contributer there. After that, set your afc for a global -33% or so should put you near stock flow again, and make SURE your turbo is set as low as it will go. If it can go to 9psi on the wastegate set it there, and get some 85octane gas in there... that will help you pass. And yes it's perfectly fine on 85 octane with 9psi.

1) the bov was vented cause at the time i did not have a return that was long enough. i asked to borrow/buy one and the only response i got from that was "he'll race you for it". thats just gay. thats all im going to say.

2) the car was tuned very well w/ stock injectors, and decently w/ the 680s(afpr solved my problems). i didnt turn the afc down for the heck of it. like i said i wasnt planning on getting it tested til prolly june'ish, but my parents basically made me regaurdless of how many times i said "its gonna fail miserably"

3) At the time, stock, now buschur

4)walbro 255

5)Because im broke. Im buyin a 2g maf from marcus for now

6)yes, charcoal is/was. pcb was/isnt at the moment.

7)My palm got stollen a while before this all, i just got a new one. now have a new logger.



Jake--Thanks, thats pretty much what its at now. i should have no problems now that i have a new return and the afpr solved LOADS of problems. ask steve how ungodly rich it was. we shall find out thursday when i go back.

680's and negative teens, yep set to fail and be slow. Like already mentioned, you want it set way leaner.

The turbo really has nothing to do with your trims and passing emissions.

As for the evap, it depends on how they tested it. Could be just the cap. On 1g's it's all basically inaccessible.

The good news is I just passed with 720's, cams and a Magnus intake, hehe. :p

For #1 go find a radiator hose that'll work. End of story, make it happen.

Better make sure your trims are right with that new logger, before you head back.

Yep, like Vern said and I stated earlier you should be at about -33% in your un-boosted areas and scale down for boost levels after that, not teens.

Wait why would you want to run on lower octance gas, I though that you should runner higher pump octance.

Less of a chance of the sniffer picking up unburnt fuel. Speaking of emissions mine is due this month UGH.

How to pass:

1) New plugs (BPR6ES), properly gapped
2) Make sure your fuel trims are within reason
3) Install your cat-con
4) Drain the high ocatne out and put in the lowest octane you can find. It's more volitile, so it burns more completly
5) Make sure your o2 sensor is good
6) Toss in a bottle of that guaranteed to pass stuff
7) If you have your timing increased, zero it out
8) Make sure your idle is set properly

My heavily modifed GSX passed the tighter IM240 test for 98 and newer model year cars by a wide margin, even with Crower 414 cams.

like i said, i knew i was gonna fail. it was at like -19 on the afc. still not low enuff. the bov is not vented any longer, cat is on(was on before the last test). going to make sure the fuel trims are set properly before i go back as soon as i have a day off, gonna change the oil RIGHT before i go. where can i get a bottle of that garunteed to pass stuff?

Remember to heat up the cat as much as you can right before you test it; catalytic converters need heat to make the reaction happen.
