I just got the bike back from the dealer from the 1000 mile service. Not that that means anything but I suspect all of that is good to go. After that service is when I installed the pipes, AC and tuner. Only sitting at 1300 miles.

take a look at your AFR table. maybe take a little bit out in the area you're seeing the retard and do another tune run. See if that helps, if not then I would move onto timing, removing only a couple of degrees at a time AND keeping in mind that knock retard is actually happening BEFORE it shows up in the logs so you'll have to go back a few frames to determine exactly where it happened.

UltraNutZ I do appreciate your help and I am actually beginning to understand what is going on. I am not really sure how to proceed and was hoping you or others would weigh in.
I have my ST dialed in, all cells within 5% between runs. I can feel the improvements from when I began with the original tune. After all that, when I do a data run (ST flash disabled) I see a consistent spark retard in the rear cylinder only. It is also in a wide swath. TP 15 to 60, and RPM 2000-4500, during moderate acceleration. This seems like a wide area to adjust the VE table, but then again it would be the same area for the AFR table. The retard peaks at 9.25 degrees while the front cylinder would be at 0 retard.
Being the rear cylinder only, I assume I should stay away from the AFR table and concentrate on VE and timing? Which of these should I start? Does the large area seem normal?
Rear VE table attached with intended area to increase

I am missing something?
are you looking at the histogram for knock retard and front is a flat line, but rear spikes 9.25*?

Blue is throttle, red is MAP

Victorsam,
I received your DTO and #7,8&9 HDX files.
1) the spark advance has not been changed.
2) the VE has changes of up to 20
3) HDX 8 &9 has knock on front (small 0.5) & rear up to 9.75*
4) HDX 7 has knock only on the rear, but wow a lot of knock from 1500 to 5000 rpm
you are using Map 617SEB203 which is correct for SGS 2014.
problem is that you have a continued knock without explanation in the rear. Timing on the base file has not been changed, I would not expect it to be out as far as the knock suggests. VE on new has not changed enough to introduce lean knock. something else is going on here and not with your tuning attempts I suspect.
what octane gas are you using, bad gas maybe?
The rear O2 sensor may be bad
This may well be a warranty issue
