Well all I am seeing is if it throws a code its stored so if no code no storage. Will get into the tool to look for more. Who knows though whats all in there that can be accessed by Yamaha.
Boys that YDS tool is really a heck of a neat thing but crazy all that can be done. Lets put it this way at PDI if connected and it should be to register the Vin. All values of every sensor while running are stored for future reference in the "Cloud" They can also be printed out for the owner showing anything out of spec. Graphed in real time just like any other Data logger. How far back the thing Datalogs the tech did not know and manual did not show. All the stored info is available to any dealer through the tool and YDS. Its a database which should help in diagnosing issues but it also will definitely show a modded sled. Could there be ways around that. Maybe.
Also found this in the 2017 Technical Orientation Manual according to Yamaha the knock sensor is working. Of course subject to change.

Great info steve,can you find a code for boost leak,or any code for boost period,cant find any three diget or 4 diget code like Ben said he has seen 1236 looks like our set of codes don't go that high.
Here is Data logging
Will take a look. 13,14,25,26 are all boost related codes.

Not trying to stray off topic. So this is what I was referring to Steve to see if lag shows itself diagnostically. Probably monitors more than the aftermarket loggers, but I still believe that it should eliminate guesswork and speculation. From Amsnow and Yamaha engineering manager last spring.“The main goal of the 998 Turbo engine was to achieve the ultimate throttle response, or zero turbo lag,” Vizanko explained. “Our whole design and development plan aimed at that as the primary target." "Yamaha’s new engine takes that pressurized air and silently recirculates it into the intake line, keeping that boost pressure on tap and ready for the next time you instantly get back on the gas. This means instant boost, no lag, no funny noises." So according to them, it should not exist.

They were eliminating the corner to corner lag that you would get with a conventional aftermarket turbo kit. Anyone that had an MPI or other kit on a viper knows what I'm talking about. My viper had a huge lag on every corner exit where you could feel the turbo spooling back up. On the sidewinder that is completely gone. Off the line is a whole other issue that can't be completely eliminated in any turbo system. You can make it better by quick spooling it but if the turbo isn't already up to speed from running it hard there will be some spool time to get it going.

I've seen sd_26 many times after a long wot pull! Doesn't affect performance, just shut off/on to reset. Any idea what causes this?

Loose clamps on your Turbo tubes.. ESPECIALLY the one that comes off top of Turbo.. I actually put a wider clamp on.. I had this code a few times and after really tightening down all clamps and changing out one.. Not anymore..

Correct,that is why every drag racer who runs tons of boost,still need the anti lag flash for just off line,the stutter box system,we hear from apro race sled,on line,heck even ben runs one,when he raced the older cat in his 141 mph 1320 vid.

Not sure what these two codes mean,but they (Yamaha) call them upstream pressure sensors (pc) on both 25 and 26 who knows is this some kind of boost code?

Are you running stock tubes? Mine are outfitted with Alpha tubes and CAI kit,and there clamps are realy rugged and you can tighten them with a lot of torque,no codes on mine yet,but we only have 635 miles,until todays end,maybe 750,by days end.
