Although this problem doesn't show it's ugly face as a normal experience it does happen at times. This is not a TTS problem, this also happens with all the flash tuners and even the digital tec. The problem is in the 2014 and up ECM's. The can handler gets a little confused at times in these new ECM's among other deficiency's it has experienced since 2014.
I don't believe anything was corrected to delete this problem in the new ECM's so we have to live with it for now. Again it is not a TTS problem.

You won't have any problems down the road with normal operation of the Bike. However if anything is flashed into the ECM, any programing that is, it can jump the mileage again. I just did a 2016 last week that had 100 miles on it and when I flashed a base map in the ECM the speedo jumped to 145. I programed the ECM about 10 times as I was tuning but the speedo never jumped again.......it's rare but it does happen.

Doc,

Just tuned a 2012 with SESP and I have the newest update cals from them .. Speedo reads fine however in 25 miles approx the mileage went up 280?

I have tuned that bike before without issue. Only thing was new build and the newest update from HD.. Not sure if its related but just thought I would post on what I just saw on a HD tuner.

Milage went up on my 15 when it was tuned. Same with my wife's 15 when it was tuned.
