Well I got my new SERGU on Monday, on tuesday with 180 miles on the bike I added the Fullsac DX head pipe, 2.25 core and screens.

After I was done loading the map 3 very strange things happened.  This is also the 5th bikes I have used TTS and Fullsac on.

1.  Trip A went from 79 miles to 41.9
2.  Trip B went from 180 miles to 41.9
3.  The odometer went from 180 miles to 222 miles.

Has any one else every seen anything like this with the TTS tuner?  I sure have not.

What you have seen, happens on 2014 and 2015 Touring bikes with no reason. I personally reported the issue to HD and it can happen anytime the bike is programmed. Problem is we saw the same thing with a dealer program from DT as well! So it's not only a Mastertune issue but a DigtalTech does the same thing! You can program a bike 20 times and it will never happen then program it once more and it does. We are a little at a loss on it but know it can happen. It is something with the new ECM and Odometer combination they started using in 2014 touring bikes only. It always appears to happen and the trip meter goes down the same number the odometer goes up. In your case the trip meter went to 41.9 and the odometer went up 41.9. I have seen them move by 1 or as much as 45 so far. Since it was all new then I had hopes they would solve it by now, but nothing so far.

Well that is interesting Steve.   The last bike I did was a 13.   So I could happen again when Doc tunes my bike during Biketoberfest?

[Steve Cole]

I am not sure as I have programed my personal 2014 about 1000 times and it has only done it twice. The 2015 I just finished testing 20 + camshafts and 100+ tunes never did it! Did another 2015 yesterday and it did it first time out. Another odd thing is I have never seen or heard of one adding more than 45 while others as low as 0. So at this point in time I cannot tell you if or when yours may ever do it again. I know that doesn't help much but just wanted to let you know as much as we do about it.

[FLSTFI Dave]

Thank you for all the information Steve!

is it possible the miles came from the original bikes dyno time (miles) spent developing the tune that was uploaded into your bike  maybe remove the tune and see what happens ?

[Steve Cole]

No, it's an error in the way they handle updating the Odometer and ECM that started with the new ECM for ETC bikes.

It also happens with the power vision.
I loaded a new tune on my 14 one day and went for a ride as i watched the trip  odometer a it was going up 1 mile for every 10th. Right now I am on a trip and every 100 miles there is a 15 to 20 mile difference between trip a and trip b But I guess they all do that!!!!!!!!!!!!!!!!!!!!!!!

Well Like my first post it was 41.9 miles it added to my FLTRUSE.

Just did the fullsac DX head pipe and CVO mufflers with 2.25 Fullsac power cores on  my wives 15 FLTRXS using the TTS again.

It only added 20.9 miles to the odometer and set both trip odometers to 20.9

Next time we load a map we are going to set both trip meters to 0 first.
