CA ECU Smogging
Hi forum,
Now that CA is going to start scanning ECU for tune, what are the tuned guys gonna do? Personally, I am not tuned but I was planning to go FMIC, charge pipe, intakes + tune sometime in 2022, but it I’m not sure if that’s still a good idea. Is there a workaround to the whole ECU scan thing?? Do I settle with the old Dinan or PPK (if you can even still get that)? Let me know your thoughts. |

You can probably get away with a fmic and chargepipe when it comes to the visual. I like to put the stock airbox back on to hide the chargepipe and to eliminate any doubt that the car is modded, even though the bms dci’s are carb approved.
And as for the ecu tune, if you have mhd then it’s a simple flash to stock and you’re done. |

IMO yes, in terms of performance and sound. Only downside is having to remove them for SMOG testing |

I failed smog last year and had to go to the referee…. After 3 tries I finally figured out it was the m3 gauge cluster that was causing it to fail. Giving a incorrect checksum number and instantly failing. Now I’m worried the mmi I added for the CarPlay will might do the same. Anyone else had issues with electronics??

is it a high chance to pass with inlets and outlets or did you just get lucky? i remember when i went to get smogged, the dude spent like 10 minutes with a flashlight to look under my hood and even though im still stock for now, that shit made me anxious as hell

Damn, I just failed for a aluminum charge pipe on my n55. Didn't feel like changing it so I took it to another place to roll the dice and they failed me also for the charge pipe . Guess I'll just put the stock one back on and get a free re-test that the second shop offered me.
