am at stage 3 any thoughts on passing ca smog 2016 f type r no down pipes just upper and lower pulleys and stage 3 tune thanks in advance

 

May or may not pass depending on the station. Use one that has a retest at no additional charge if the vehicle fails.

 

got it thanks

 

Can you elaborate on why it may or may not? Would it be a visual check that fails, such as identification of a non-stock pulley, or something in the OBDC scan? I'd expect the OBDC scan to be consistent across stations and visual inspection more dependent on diligence model-specific knowledge.

The thing I'd be concerned about is the tune being identified as non-stock due to an unknown checksum, but that subject hasn't come up in a while and I never saw anything conclusive.

 

The Technician conducting the smog check/inspection may or may not identify any non CARB certified parts, such as catalytic converters. It also depends on the algorithms built into the test console software to detect a modified PCM such as what a Jaguar main dealer can detect.

If there are no pending or permanent DTCs stored, the vehicle may pass with the modifications the OP mentions. If not, hopefully it can be returned to the factory default parameters for a retest.

 

That's the $64 question. The P0167F code by itself doesn't indicate that the software is modified, just that a non-OEM device was used to make changes at some point. It remains if the original file is restored, so cannot be relied on to determine present state. More sophisticated checking would be necessary and there seems to be a dearth on information on the subject.

 

You should be fine. The tune didn't affect me at all. It's the visual that'll getcha. Pulleys are fine, they likely won't even know the difference. Cats however, can fail you. Especially since they say velocity ap on it🤦🏾‍♂️.

 

Waking up this old thread since cars delivered in 2015 (MY2016) are now due for the first inspection. Anyone have more experiences to report?

 

I just had my wife's Cayenne smogged last week and asked the owner of the smog shop [test only] what his opinion was on my tuned F type. He told me that he has had four or five tuned cars fail since the law went into effect [none were F types]. They all rolled back the tunes and subsequently passed. He also mentioned that he has absolutely no control over the process what-so-ever.

He suggested I do the same [plus drive the car for a hundred miles or so after the de-tuning to reset]. Mine's not due until '26 so I am not sure I'll even have the car by then [although it must be smogged when sold].

 

When the time comes, get it tested, as is, and only roll back the tune if it fails.

 

That's kind of what I am thinking.

 

Why borrow trouble when restoring the stock file is so simple? It takes less time than having to go for a retest, plus avoiding a failure for cause on the record is not desirable.

Restore original file, drive a bit (a few trips, some miles, some start/stop), stay out of the high-throttle/high-rev zone to avoid an overboost CEL, pass the test, and Bob's your uncle. Oh, and check that you don't need to do a battery reset afterwards.
