Help a noob (fuel programmer)

Couple of questions:

How do I know if there is a fuel controller on my bike? Where do I look for it/what would it look like?

I'm presuming that by disconnecting the battery I am going to lose whatever tune/program is on the bike. Is there something I can do first to save myself from needing a dyno tune?

Sorry for the noob questions. I was a carb guy before getting a 2010 'Glide. I bought it used, might need a new battery and am new to Harleys so could use some help.

There are a couple of different programmers that would be on your bike.

1) Add on
2) ECM Reprogrammer

Neither should lose a tune if you disconnect the battery

If you have the add-on, it should be plugged into the 'ECM' which is attached above the battery. These add hardware onto your bike.

If you have the ECM reprogrammer, it would have come with the bike. They are 'married' to the ECM, and can't be re-used. These just re-program the factory ECM, the nice thing is that you don't need to have additional hardware on your bike, that can stop working, and then your bike would then die, or go back to stock tune, which could be really bad IF you have a cam in the bike.

Most bikes out there would most likely have a 'HD' tune, or a tune that is downloaded from the dealership. These are usually very LEAN and run hot.

Anyway, hope this helps!

Like Gus said, you will not lose a tune by disconnecting the battery with any tuner. You can check the bike's serial number at your Harley dealer, if any dealer changed the ECM calibrations it will be noted.
