I have a 2014 Heritage, prior to taking delivery I purchased and had the dealer install the Speedo/Tach combo with the 600 lights etc.
now, I want to switch back to stock and will sell the other. I did a little looking around, I don't seem to have a cable to transfer the mileage, does anyone know how this would work? I want to have my original speedometer set to the correct mileage of the bike, and I would guess whoever buys my speedo/tach would want that to match theirs as well.

 

If you put more than 31 miles/50km on the speedo/tach combo, it is permanently married to your bike's ECM. It won't work on any other bike. Sorry.

 

Wow, I had no idea, glad I asked the question, I have put on a few more than that!! Thanks

 

No problem. The only reason I know it is because I installed one on Reaper, and it's stated in the instructions.

Sorry to be the bearer of bad news.

Cheers!

 

Correct..

 

Although if it you could change back I believe there is an odometer saved in the PCM somewhere because my tuner will get an error code once in awhile that the two are off and the computer will automatically adjust the Speedo to match. Maybe I am wrong. I am fairly new to the HD computer system.
