I think the guys at the STAR stations are being very cautious right now. Two places I went yesterday did a lot of looking around under the car. And both guys asked if I had a carb number for the downpipe. Never seen that before.
I would think the regular shops are probably conducting business as usual. Not sure though. Edit: what did you use to check the VIN and such?

VIN doesn't and won't matter, if it is in fact your car that is being tested then it wouldn't matter if you have swapped ecu because the test is being performed appropriately. |

Whew, that's a relief (if VIN/CVN/CID won't matter).
Btw, I used FreeSSM to check VIN. I wasn't sure if a tune could change that or not. Maybe a tune can't, and I was worried for no reason. |

Been gone for a good minute looks like it is time to chime in again:
For now STAR stations means they are smog test only and repair. In other words they combine both stations into one. The downside STAR stations are very very cautious since they avg for the smogs has to be lower in order to keep the STAR standing. This means any and I mean any modification (yes you with CAI) that does not have a carb sticker will fail visual. For now if you have a tune you are safe but implementations are being set forth by the state that maybe next year it will check to see if the ECU has been tampered or modified. So that will mean stock flashes back if you want to pass smog |

What if your car was bought used with a tune (just for the CARB legal CAI)? How would I get back to a 'factory floor' tune? Does the factory tune include some code we are unaware of that identifies itself as being original? |

Not sure how the ECU works but it is possible that it generates a checksum or something based on the tune loaded. I'd call that fairly unlikely but you never know. Now maybe an ECU for a GT-R might do something like that given how hard Nissan tried to lock it down.
Most likely there is some identifier that is programmed into it. Loading a different tune may or may not change that identifier. |

That won't affect it. The only obvious way to fail for that is to have a swapped ecu or a standalone

Note: be sure to drive the car and have it warmed up prior to smog. It gives a better chance of passing. |

if you bought it used then you'd have to contact the dealer to get the original stock tune. Again it is not set in stone but a heads up that it is coming down the pipeline soon |

Of course it all depends on how that checksum is created; whether its just parameters in the tune itself or there could be something else its looking for. The former might be easier to work around; flash a stock tune using an AP and it should be kosher. The latter could be tough...like maybe a flag that's set when you alter the tune with an unapproved device? No idea, just thinking out loud.

btw if you are catless and run the cat delete bypass (so it wont pickup that you dont have a cat and throw the check engine code), it might not pass smog as that monitor will never get set, as of now as long as 1 monitor is incomplete and the rest are good you should pass but next year all car over 2001 HAVE to have all monitors set

When you are talking about the cat delete bypass - do you mean in the UP or DP?
I have an '05 LGT with an STi UP (OEM UP has a cat in it and EGT sensor). Will the resistor mod for the EGT be ok for that? If not, what if I take an OEM pipe and de-cat? The EGT shouldn't be able to tell there's no cat in the UP, should it? I have a gutted (1 cat removed) OEM DP, but I have a fully OEM DP ready to put on for SMOG... Also planning to go back to stock injectors at some point to be able to run a 100% OEM tune for smog. |

I think I've figured this out by reading through this forum, but I figured I'd get some verification. I'm new to CA and last had a smog check in Utah, though I ended up moving before registering the car there.
I'm running a 2006 WRX wagon with a Cobb turboback, stage 2 AP tune. I should be OK if I throw a stock DP on and reset the AP back to stock, right? Also, does CA require you to show a previous registration, or can I just start from scratch here. My VA registration expired a few months back, and I just found work out here, so now I can take care of all of this. Also, I've seen some stuff that makes it look like they just do idle tests, but I've also heard I need to find a shop with an AWD dyno for the test. Which of these is correct? I'm in LA, Silver Lake/Echo Park area. I've had friends in Virginia and Utah who would run the test legitimately but "miss" the top cat on the downpipe during their visuals. I always passed in both those states, even at stage 2, for what it's worth. Thanks for your help. |

FYI I passed the smog check today. Car was running rich, someone told me to add a bottle of fuel additive called HEET. Went to Oreillys bought a bottle on sale for $2.50. Added the bottle drove on the freeway for about 25 minutes to the shop.. They tested it and passed no problem at Stage 2, 3076,750 CC DW's, inverted custom air intake taken off replaced with a legal Cobb air intake with CARB sticker and put stock DP on it. Friend told me HEET makes the car run cleaner and not as rich. It did work and I dont think it would have passed without the HEET...
Anyone else ever try it? |

You should be able to pass with a stock DP. I wouldn't bother with reflashing to stock. You don't need to worry about showing any previous registration to get a smog check that I know of. And finally there is no need for you find a shop with an AWD dyno. Any shop will do a 2-speed idle test and that's perfectly fine. Good luck! |
