I've got a 2nd gen 2017 CX5 running an R7 on 135 with occasional rear antenna falsing at 24.123-24.124. Need to check my settings too confirm K% and rear balance, but I'm running MRCD on as recommended. It's mostly quiet. Going to check DC's other thread to see if there's anything I can do to make it better.

Thank you for the find @DC Fluid !

@Vortex if you need a CX5 to test against, I suspect I'm within 20 minutes of you.
Ah cool. Does MRCD on do the trick for you with the R7 inside the CX-5?

This'd make for a pretty quick and easy test to confirm for people. Shoot me a message and we can set something up. :)

I have had one instance of deliberately trying to provoke an alert to a CX-5, that point blank, less than a car length, the BSM broke through the MRCD trick.
Filtering resumed when backing off a few more feet.
I think CX-5 owners will have to play with different combinations to get a balance.

I'm running the settings you list as your preferred ones which include MRCD on, it's nice at quiet with the exception of occasional K false to the rear antenna to the CX5 itself.

So if you try some of the suggestions in the other CX-5 thread, do you get the occasional one eliminated?
E.g. rear horn reduce by 10%
K Band Advanced reduced by 10%

It would be interesting to see final happy settings for many CX-5 owners posted up for quick setup out of the box.

So many are afraid of getting a detector and find it unusable in a CX-5, and the R7 is one of the only ones to have all the tools available stand alone to work around the issue.

Please try out stuff and report back, this thread would love to see a working setup.

I'll be playing around with those two settings to see if there's something which completely eliminates it. Will update in the other thread as I get around to tinkering. Once I find something which seems to work I'll report back here.

Thank you @Vortex for providing a solid starting point.

Alrighty so I just had a chance to meet up with @YelloEye and we spent about an hour playing with different detectors and settings. I'm gonna review all the video footage to go over the results and then do a summary video, but a few quick thoughts.

BSM testing is weird. Falsing was kind of intermittent. I could sit right behind the CX-5 and the signal would come and go, depending on the detector and settings. We tested with the R7 in his car and with all the settings cranked up, the detector would false constantly so the CX-5 is emitting constantly. It's just the detectors alerting intermittently.

For the R7 (1.35), both MRCD and TSF helped with CX-5 falsing.

The R3 (1.54) didn't do as well, even with MRCD and TSF on.

The V1 Gen2 (4.1023) would false in both l and L mode, though L mode did help reduce the falsing somewhat.

Surprisingly the RL360c (1.7) wouldn't false no matter what I did. At first I thought it was just the Escort thing not alerting to any signals at startup so I tried starting the detector and blocking the horns for a while. We tried starting the detector with the CX-5 off and then only starting when the RL had been running for a while. Detectors generally did better with driveby testing than when sitting behind the car, but the RL didn't false at any point. (This is with the RL in Highway mode, K SW off, K segs 1-3 on, TSF off, MRCD on, and MRCT off. I didn't try changing any of those settings.)

I also saw additional weird stuff like the R3 falsing as I was driving and pulled up to park behind the CX-5. I could drive backwards away from the CX-5 and it would keep falsing. Eventually the R3 would stop falsing and then I could pull right back up to the CX-5 and the R3 was silent.

I was hoping to see something like "Run this detector with these settings and boom, the falsing is reliably fixed," but results were much more variable and inconsistent so I'm left more confused than I expected.

I guess certain settings can help to reduce the falses, but that doesn't mean that they will fully eliminate them, depending on certain conditions.

BSM filtering testing is weird...

Any way to confirm the CX-5 is constantly emitting a steady signal?
I've seen many BSMs with on/off behavior.
Of note, was a Pacifica that emitted a 24.160 & 24.168 signal from the rear, one when directly behind, the other when at the back 1/4 panel area. Different sensors (I think 4 at the rear?) with different frequencies, and they ALL stopped, when the vehicle came to a stop at a red light, and immediately turned back on as soon as movement started again.
So how these BSM systems work may be more complicated than C/O radar.
And we thought speed signs were unreliable. LOL.

Yeah we tested that. With his R7, if he cranked down some of the K sensitivity and rear bal, it would reduce the false alerts in his own vehicle. Once he cranked everything back up to 100% though, constant alerts the whole time. So the signal is transmitting continuously. Left us scratching our heads even more, haha

I might have to try my tuned Bushnell 24.124 at distance against my RL360c if it ever shows up.
Maybe a hidden K Notch? Or secret BSM sauce?
Now I just got ta know!

This is in line with what I see in everyday driving. My R7 seems to handle CX-5s considerably better than my V1G2. My R3 barely falses to them, but I have 1.50 on it and I noticed CX-5 falses go up considerably on 1.54.

Interesting to hear your results with the R360c. Escort figured something out with their filtering.

Can't wait to see the video!

If anybody has an SDR capable of 24Ghz we could try to analyze the difference between BSM and a radar gun asking with finding out how often the BSM heads are transmitting. I think that's part of what Theia is working on accomplishing. On the CX5 so far as I can tell it's constantly transmitting, parked on the side of the road with @Vortex behind me I was catching 1-4 signals on ~24.124 running max sensitivity no filters on the R7 in the cab.

You are reading my mind. I will be rolling my R1 back to 1.50!

Okay video is now live going over the testing earlier this week with @YelloEye's CX-5.

It's the same stuff I mentioned earlier, just now presented in video form so you can see now too. :)

Wonderful video, thanks to you both!

I got my Redline 360 yesterday and will observe the CX-5 interactions.

Of note, regarding RL360 filtering, I don't know what is going on but I have and old speed sign in town, hooked into city power grid 24/7.
Yesterday first pass ever the RL360 refused to alert to the strong 24.050 ish signal until I was right beside the sign, when I received ghosting 24.080
Every other detector I've had sees this sign and alerts at 1/2 mile out, where it comes on after rounding a curve.
I've noticed several door openers that alert all other Escorts I get no alert driving by.
This is all good if the Redline continues to alert to real police radar guns reliably.
So far range is besting my best R7.
Both are actually rather excellent on BSM and falses on the latest firmware.
More than 1 day required with the RL360 though, and Max 360c delivery expected today to complicate things. LOL.

Yeah it's seeming like the filtering we're seeing added is doing some weird things.

I wish it was as black and white as saying "This detector with these settings fully eliminates falses from CX-5's or speed signs or whatever" but it's like we're sort of in an intermediate area where it's trying to do some more filtering, but it's only somewhat successful.

As long as it works fine against police radar like you said, then I hope we continue to see further development and refinement here.

Good info summary. Man that was a fantastically warm and sunny day. Can we get that back? Thanks for the testing!

lol no kidding! It's supposed to be rainy again this weekend. So nice to take advantage of a sunny day and do some testing! Thanks for your help in making this happen! :)

Happy to help and of course available for future software update testing. I was really hoping for a top down weekend in the Miata, doesn't seem to be in the cards for this one.

Thanks to both of you for this testing! Interesting results. Doing BSM filtering testing under controlled conditions is tough. This is definitely a step in the right direction.

Yeah, it makes me wanna brainstorm other techniques and best practices for situations like this when we can get a BSM transmitting car on hand to test with.

I'm pretty relieved to find that the signal keeps transmitting continuously and when parked, at least in this case. It'd be harder and more time consuming to test if it only worked when the vehicle was moving, for example.
