CT emissions Stage 2

MaxM97

Ready to race!
Hey everyone,

Anyone have problems passing CT emissions with downpipe and stage 2 tune? My current tune shuts off the cel for P0420 code however the code will still be on in the background. I do have a vibrant spacer to play around with as well.

Thanks

Not sure about vibrant, but I heard this spacer works with well with the IE pipe.

One or two monitors would not set. Can’t remember which right now. I did put the vibrant spacer on today, we’ll see what happens this week as far as CEL and monitors go.

I think any tune that disables the CEL will keep the cat monitor from being set. You want a tune that doesn't disable the CEL and get the spacer to keep it from popping up.

The P0420 code will still be on, however the light won’t turn on I believe. I’ve got about 100 miles so far with the vibrant spacer and no CEL or codes.

did you ever pass emissions? I am just wondering since I will be soon in the same boat :)


I just swapped back to Stock DP and flashed backer to stock. I got the DP swap down to 1.5~2 hrs so not a big deal for me. However now I’m reading a straight style spacer works best on the IE downpipe, so I may try that again next time emissions comes around.

WTF, so are you saying to failed emission with the spacer?
I have no check engine light or anything but I really don't want to swap DP every couple of years either....

Didn’t fail emissions, just couldn’t get my readiness monitors to set and getting P013E and P2270 with IE downpipe and Vibrant J spacer. Easier to swap stock back in for me rather than experiment with spacers.

What are those two codes? I had a IE pipe installed with a straight Vibrant last weekend. No cell. I've flashed my ECU twice and achieved readiness twice now.

Stuck lean codes, can’t remember off the top of my head the exact wording. I was using the CURVED spacer. I’m running no spacer now with no codes. Will try the straight spacer next time.

Just looked up the codes. Delayed response. The J spacer opening is to the O2 sensor is pointing up? I don't think the J's are great for the stock location CAT pipes. Definitely try a straight spacer. A straight one will pull the sensor out of the flow, but the gases won't get stuck in the spacer. I think the gasses flow through the straights better.

After the DP install, I did notice my cruise AFRs were a little wacky each time I flashed. This is not normal but the car figured out the trims. I guess I'm still within the limits.

hmm, i have apr downpipe with race cat for over two years now with a spacer and no cell.
I am assuming I have achieved reediness by now, but how do I check to make sure?

When I check the codes I do get some type of warning about the cat, like not able to sniff the fumes or something to that regards..., but since I have no check engine light I figure it is fine...
I am still about one year away to emissions... just do not want any surprises.

Thanks

I'm using OBDEleven to check readiness. VCDS will do it also if you want to go that route.

Your APR stage 2 tune probably codes out the CEL like my EQT tune. Doesn’t necessarily mean your readiness is set. I check readiness with my Cobb Accessport

ok so I checked for Readiness, and everything says, "completed successfully", but:

"Number of emission-relevant DTC memory entries" - 0
"Malfunction indicator lamp" - OFF
"Monitoring of catalytic converter at operating temperature" - Not activated

I did this while the car was off, not sure if I should check while it is on.
Based on the above, does it look like I would pass emission?

Thank you

Do you have a tune at all?
