I could be completely wrong, but I don't think anything OTA would effect the tune. More than likely OTA updates are simply an update to the infotainment and other possible software updates. Things like the ECU tune that controls AFR and timing are firmware, which requires you to be plugged into the OBDII to make the changes.
That being said, I'm sure you'd notice the power drop off if the tune did get wiped from an OTA update.

Looks like the latest version of the Ktuner SW is 1.0.9.2. Here is the version history but it doesn't say the RDX is in it from what I can tell u
Version History
Version 1.0.8.5 is when RDX support was added.

They update quite a few vehicles, with all sorts of enhancements, which may make into the RDX. hopefully..

I didn't see the tune in the version control list for the 2020 RDX but I don't know the associated ECU numbers and they are different than the 2019's. They were added about a month ago. Likely they might have just ported most of the tune over from the 2019 code.
From the times I drove it, the tune seemed pretty solid. I just wish the very solid midrange pull extended into the top end. It seems stock and tuned this motor is less of a revver than I would expect. Maybe there are some significant breathing limitation for high RPM HP. I've been tracking my car stock and it almost never shifts much beyond 6k at WOT.

I will report on the stage 2 burn soon, including MPG, butt-kick measurement, rpm hanging and general 'normal' driving experience (traffic and otherwise). So far, with only some tooling around and a few WOT's, I find it awesome. Not only the power increase, but the way it handles itself with normal launches from 0, 10, and 30 mph. Very well done so far.
...also, which was mentioned by someone before, the brakes appear to be harder, and the sport steering is a bit tighter. i assume it is because they used the latest factory ECU settings as a base. My original ECU was A88.
... and I used Parallels running Win10 on my Mac laptop to burn the V1.2/ECU.

The mpg of stage 2 tune did not change from factory tune. If you don't keep mashing that pedal, the tune keeps the car in as high a gear as possible and feels conservative, but it reacts faster from a mash. And when you mash, and you are moving, the turbo feels already spun up, or spins up faster/earlier, along with the 60 more lbs of torque.
I did not do any 0-60 times at this time. The published hp and torque curves should explain alot.

FYI, I found my old OBDII scanner can read calibration identification. To my surprise, the ID is 5YF-A860. Not sure what's going on as my ECU part number is A87...

Everything can be removed after you load the tune. The Ktuner does have data logging capability though that can help you see what is actually going on such as knock counter to see if you have any issues with your fuel quality. For the v1_2 you'll need a laptop to collect and view this data.

Found this post from Derek@IMW comparing the two tuning options:

Seeing this list before in a post from Derek is what steered me to Ktuner for mine. Used Hondata on all of my previous vehicles, but for the new DI turbo cars Ktuner looks to be the best path forward.
