ANC & ESE disabled with Carista app and my OBDLink MX+ module.

[RunnerRocks]

Purchased Carista app to use with my OBDLink MX+ module.

Adjusted the following settings:

Lane-change turn signal auto-flasher count = 5
(I change lanes cautiously, 5 flashes if better)

Engine Sound Enhancement (ESE) = OFF
(Finally can hear the natural sounds)

Active Noise Cancellation (ANC) = OFF
(Appears to have eliminated the mystery rumble)

Does the noise in the cabin seem louder now with the ANC off?

I haven't noticed it being any louder.

Sounds different, more natural?, not sure about louder. My AT tires sound more natural without ANC. Need to drive more and have a passenger toggle ANC while maintaining the same speed, if possible.

I have not tried this. Can you have a passenger adjust the setting in real-time while driving to see it immediately? Or do you have to be stopped.

Not sure, that's why I stated, "if possible".

I'll test stopped while in D, then at crawl speed first.

Full reading comprehension is important. I read too fast and got excited when you said have a passenger try and change settings and missed the, "if possible". Let us know when you can. I can also try it in my cul-de-sac at a crawl tonight if not.

Awesome! Thanks for the input and in advance for the test.

Tested toggling ANC on & off today while driving. Carista doesn't care if you're stopped in D or driving down the road. Drove in Normal drive mode several miles at various speeds. A mix of climbs, flats, and downhills. Had my co-pilot toggle ANC on & off during a unchanging segment.

If ANC is working, it must be very subtle. Not knowing how ANC works, it may have a sample time longer then our on/off toggle periods which might null out any possible noise cancellation.

I'll test again tomorrow on a gentle rolling 15-20 mile stretch of 65 mph 4-lane.

Tested toggling ANC on & off while driving again today. This time on a gentle rolling 15-20 mile stretch of 4-lane while varying speeds between 55 and 65.

ANC is noticeably cancelling a subtle low frequency droning sound. The change is noticeable within 1-2 seconds of tapping the Carista SAVE button. Perhaps exhaust noise, just a guess.

That low drone may be what some of us have occasionally heard that resembles rear diff noise. As some suspect, ANC may glitch and pass the noise at times.

For now, I'm leaving ANC off. When we take a long trip, if the drone is annoying, I'll switch it back on.

Interesting theory on ANC being the source of the rear diff noise. Never thought of that being possible cause, but makes sense.
