Was City Mode this impotent under the previous firmware? Yikes. City Mode? How bout Sitting Duck Mode. I had a 1-2 sec warning on a legit K with escort in Auto mode. That's too close. I am guessing Escort's Auto Mode is way watered down too.

I have a question, why is it in testing it seems k band gets the most attention but on the highway Ka band is more predominant?
I think it is due to all the K band junk out there BSM's CVS,Wallgreens etc vs KA has nearly zero falses. Users want to filter as much of the k falses as possible but still have enough of alert distance to avoid being in the capture zone when the RD alerts. I for one want to find the sweet spot, the settings that give me the least amount of k band falses but still provide 3-5 seconds of time for me to scrub some speed before being owned.

Look at my test and read my conclusion. I'm not going to argue with someone until they see what I'm talking about.

I plan on just reacting differently when running reduced % advanced mode. I am going to treat all k alerts as real when running in wide open areas...there just isn't enough time to brain filter (is that a bsm, or real?). I am going to try reacting like it is a ka alert and just get on the brakes as soon as it alerts and see how well that works.

Just make sure you don't have a late model Acura in front of you before you slam on the brakes :) I was behind a ILX (I think) yesterday and it was nonestop triggering on Highway and Advanced set to 50% KA. On city it was quiet. This is with K filtering enabled.

Did you try it down at 30% by chance?

You probably don't want to reduce Ka to 50%, did you mean K band?

Acuras are a pain regardless :/

For those with the R3/1 and access to a radar gun... If time allows, could you do some actual advance mode testing to see if the sensitivity numbers actually correlate to real world testing?

I'd love to see how much range one actually loses based on the different percentages.

Thanks!

I've seen that in the past but it doesn't address my question..

For example... made up numbers...

Say @ 100% it picks up at 1000 ft. Does that mean 60% = 600 ft, 40% = 400 ft? I'd love to see how much distance is actually lost from 100% based on the sensitivity percentage.
Yes, all other factors being equal, that's what appears to be happening.

In post #1, I ran the calculations showing that the reduced sensitivities would give you an expected drop in detection range corresponding to the sensitivity percentage (eg 60% sensitivity would result in a detection distance of 60% that of highway, like in your example). In post #3, I noticed that the TXCTG K band tests actually show this effect in real world testing, that is the detection ranges decrease by the amount expected based on the calculations for 30% and City.

Note that the calculated difference in detection distance is based on the assumption that all other factors are the same. The terrain and conditions can and do have a significant impact on detection distances.

I'm sure it would be possible to test on a course where varying sensitivities give detection distances that match the numbers in your example exactly, or you could test on a different course where 100% and 30% give you nearly the same detection range (eg a severely terrain limited course).

Nice write up and testing! By looking at the charts, I do not think I would want to run City mode hardly at all lol--thats a huge decrease--Just something that each individual needs to play with the % numbers to find that sweet spot in your neck of the woods :)

It works out to 17.78%. The table in the OP got messed up with the switch to the new forum.

City mode is great for those that don't see legit K band threats, but like leaving it on just in case a legit threat should pop up in their area. The alternative would be turning K band off, but having to remember to turn it back on from time to time to re-evaluate your environment. I run city mode myself, and it's nice and quiet, and I'll still know if I run into a legit K band in my work travels (not likely).

I used to run my R3 in City mode every time the wife was in the car before Advance mode was released. On a trip to Maine this summer I had a CT Trooper come up quickly from behind running C/O K band. And I was able to get enough of an alert to slow down. When using City mode you need to react immediately to K band alert that ramp up. I don't use City mode anymore as K band set to 60% is a great choice for range & good BSM filtering.
