Emissions failure
Went today to get my yearly inspection. It's been eight months since .I went second stage with Bootmod3 and downpipes. The guy doing my inspection, told me my car wasn't ready yet. He handed me a piece of paper which said Not Ready Rejection. Now there are no engine lights showing on the dash. After you flash your ecu, the last thing Bootmod3 does is clear out any fault codes. So I'm wondering why it showing 02 sensor not being ready, with no engine malfunction lights coming up on my dash. Will use Bootmod3 tomorrow and see if it's showing any codes. Was hoping things would go smoothly. So much for my luck.

Your readiness monitor, however, for the O2 sensor is not showing ready which is the reason for your failure on that monitor. Even if BM3 clears fault codes that doesnt change your readiness for o2 sensor showing not ready |

Anybody else want to chime in on this. So Bootmod will not pass inspection?
I had a E92 with test pipes and a tune. I never had any problem passing an inspection. I hate to think I will have to spend my weekend, putting back on the exhaust so I can get the car inspected. Don't think I want to have to do this every year! |

Not familiar with the tuning issue, but an OBDII scanner is a valuable tool, and relatively inexpensive, to show you what could be the cause, whether emission or readiness state

Make sure you've been through a drive cycle to ready your sensors. I know you said it's been 8 months, but you'd be surprised how long some people go with their sensors not readying.
https://www.instructables.com/How-to...or-Smog-Check/ Also make sure since you're tuned that you did not actually disable your O2 sensor so that it's always in a not ready state. |

If you disable the O2 sensor it will be "not ready" forever. I don't know what the laws are in NC, but here in NY you can have one "not ready" sensor, so that's why people here disable the O2 sensor. If the shop is saying that the O2 sensor must be ready to pass then you have a few options:
- Go back to stock and ready the car each year for inspection. - Get a high flow catted downpipe that won't trigger a CEL (Some high flow DP still cause a CEL, you can also get one with a GESI certified cat like the one AA sells but they are $$ because of the certification) - stay catless and get one of those right angle O2 socket extenders that will hopefully trick the sensor to not trigger a CEL edit to include details from another post: Quote:

Just got a response fro Pro Tuning Freaks. Get this. He said it was simply a matter to flash back to stock, and reinstall the cats. I wonder how many cars this person has been under when he thinks changing cats is simple.

You can try and play with spacers (as suggested above) or mini cats but that always seems to be a massive crap shoot if it works or not Below are the list of Continuous and Non-continuous monitors for Gas cars. In Colorado which follows CARB guidelines you can have one non-continuous monitor not ready and still pass. Continuous monitors are ignored. Not sure if NC ignores Continuous and how many you can have not ready. I suspect if you are catless both the O2 sensor and the Catalyst monitors (at a minimum) are showing not ready hence why you failed. If you can get access to a scan tool to check all your monitors it would give you a better idea. Again, I became more immersed in all of this more than I ever cared to be as Colorado is super strict since they scan for tunes, etc etc just like California. Continuous Monitors Misfire Fuel System Comprehensive Component Non-Continuous Monitors Catalyst (CAT) Heated Catalyst Evaporative (EVAP) System Secondary Air System Oxygen (O2) Sensor Oxygen Sensor Heater EGR (Exhaust Gas Recirculation) and/or VVT System Edit - I found some threads that are more specific to BMW and BM3 but at the end of the day the messaging/guidance is generally the same regardless of platform (i.e. Audi, VW, BMW, etc) to get monitors to ready....Flash to stock and swap back to stock DP or try to play with spacers/mini-cats... https://f87.bimmerpost.com/forums/sh....php?t=1799389 https://f80.bimmerpost.com/forums/sh....php?t=1667211 Last edited by MSH_; 05-26-2023 at 11:42 PM.. |

This is why I opted to NOT fuck with the downpipe on this car. Having gone through this headache as well on my previous BMW, I found that bribing a guy to get me to pass was a simpler solution than a swap every year. All in all, it's not worth fucking with the downpipe.

This is partly why I always opted to wait for a decent sale to pick up the Active catted DPs with their Gesi cats. Originally I couldn’t fathom to understand the 3k price tag but having got mine on a nice discount new, I have no concerns worrying about emissions ready state in NYC. I’ve done my fair share of finding a habibi guy in the city and paying extra to get that sticker. Nice to not have to worry about it as I never stay with the stock DPs for long on my cars once I get them.

Anyway, I'm in the same boat as you waiting for a sale on DPs with GESI cats. The price is expensive because GESI went through the testing to have their cats licensed to be emissions compliant. |

when did you last flash the ecu? you have to drive cycle the car for like 200 miles after resetting ecu before you can get smogged in CA. even if you change something small via bimmercode you have to drive cycle it.
