Emissions help
I am running evolve software, euro headers, and euro s-pipe with all o2's and egt hooked up in the proper locations.
After I got my first tune from Sal uploaded I was getting an SES light so he turned down the o2's and I did not get a light. However, my readiness monitors would not reset, even with a drive cycle. There were four codes: 2C93, 29F4, 2E7C, 0000. My mechanic said to try and put as many miles on the car as possible to get the readiness monitors to reset. Unfortunately that has not worked. Sal then adjusted the tune and I do not have an SES light after 600 miles or so. But I still have two codes for secondary air and cat readiness. Could o2 spacers potentially help the issue or are there any other options besides going back to stock header setup? |

Well I have read about numerous people who have not had any issues passing emissions testing with euro header evolve tune combo. I am sure with the proper setup it is possible.
I am wondering if my sensor could be faulty or if there was an error in installation. Also Salman has been very helpful and responsive with my questions and in making changes with my tune. |

That's true. Evolve posted in another thread that they usually find this type of issue points to damaged/faulty sensors or an installation issue. Good luck! Hopefully your problem is resolved before I install my headers/cats, but if not I will share my findings.

I had no issues with Euro headers/cats + evolve. Posted about it here. I don't have the O2s turned down or anything special in my tune, with your O2s relocated you shouldn't need to.
If you are still having codes, I'd suspect the installation. How did you route the O2s to the cats, did you cut through the heat shield? cut and extend the wires? unfold? etc.

Are they routed correctly around the heat shield? Because unfolding by itself doesn't give you enough length, you need to cut into the conduit somewhat. If they did, maybe they nicked the wiring.
