I recently bought an '05 Softail Springer FXSTSi. The bike came with Screaming Eagle air cleaner and Screaming Eagle II slip on mufflers. It also included a SERT which I presume has been programed for the bike.

Now the puzzle. Included in the box with the SERT was a small electronic device I haven't the foggiest idea what it is. Its a small chrome box about the size of a zippo lighter. On one side is a bliack label with Screaming Eagle written on it. There is an approximate 18" harness coming out of it with 4 plugs on it, 2 males and 2 females, and a ground wire.

Does anyone know what this is and where I can find any literature for it? My guess is it is a lesser quality ecm fuel module to which the SERT was purchased to replace.

Do you have a picture or a part number of this device?

 

It might be a Screaming Eagle Race Tuner.
I may be upgradable to TTS Mastertune that can Do much more than the Harley SERT
TTS was the provider to Harley for the SERT But they went to a different provider when they changed tuners. It should have came with a CD also.

But based on the description I could be a EFI RACE FUELER
