I’ve passed without any issues here in Northern Virginia with a catted downpipe on all my cars to date. California is obviously a no go on anything emissions related.
I get the same thing but I am able to stream music and get Waze to work just fine over cellular data.
It comes down to the wireless connection to the car itself doesn't offer internet access (which is normal).
If they don't do visual or a sniffer test, then as long as it doesn't throw a CEL, you should be fine. Northern Virginia has emissions based on OBDII. Anything older than 25 years they don't bother.
If you're planning on modding, just buy whichever floats your boat. Otherwise, look for a stock one because they will most likely still be under the factory warranty.
If you are planning on running the flex fuel CANBUS kit from Zeitronix, then any tuner that uses ECUTEK is the way to go ATM. @Twisted Tuning , @Marin@MarinTuned ,@Marshall@ViscontiTuning , @Paynful , or any number of tuners can help you with what you are looking for.
