This may have been covered in another post, but I would like to know the answer to this question.

So if I hookup Tunecu to my Rocket and read the current map and save it to my laptop. If I then go back and change the speedometer correction to let's say... -5.1 and then upload/download the new change to the ECU. Do I need to still need to do the "reset adaptation" and the 12 minute tune since I haven't really made any other changes to the bikes mapping? My thought is...No...since nothing in the actual mapping is changed.

Also, I pulled the speedometer correction setting from another tune I was looking at and it appears that correction number reflects a "percentage" of the speedometer error. Is that the case? It would appear from my own calculations that it represents a "percentage" as that would be what it takes to fix my speedometer error base on the speed error I have been able to determine using my GPS as the gold standard.

Basically, I am sick of my speedometer being 3 to 4 mph off at speed with both with my old tire and my new tire. It just annoys me for some reason and I want it fixed!
 
Motorways in the UK are a 70mph speed limit which was set in 1965...although most drive at 80mph plus.

So you got the speedlimit, but you can register a supercharger. We got the Autobahn, but emission laws prevent superchargers ... :mad: :banghead:
 
From my basic understanding is, yes, you should do a reset adaption whenever you load a tune, period. Even one that doesn't have any significant changes.

I did the same thing recently and do not do the reset. Bike didn't run well. Did the reset and everything went back to normal.

Note: When you slow down the speedo you also slow down the odo.

Well, problem solved. As you may or may not noticed from my other post, I decided to go all out. I uploaded Wayne's remap on the ECU which had the speedometer correction In it as well. The speedometer is now correct and the bike runs better as well. I believe you are correct on the reset. My upload/download and reset went just as expected without a hitch. As for the Odometer, I've yet to get a ticket based on my odometer. :p If I ever sell the bike it will show less mileage. :rolleyes:Thanks.
 
The odo reading is important to me as I do certified Iron Butt rides often and the odo has to be accurate. Otherwise, I would do the same.

Glad to hear that you got it sorted.
 
Interesting , after map loads and reset adaption ive never done a 12 minute tune, think i'll give it a go next time.
