I have a few questions about the TFI. I have been reading up on this, and trying to figure what to do here. Mine is an '03 Ultra that I picked up used with 34K. It has 40K now. I am relatively new to HD's, and last year I opened up the Cam chest cover after reading horror stories on Cam chain tensioners. I found a gear drive setup on it, but have no idea what cams are in it, as there are No markings on them of any kind that I can find. That said, the bike is an 88 incher, and the first long trip I took on her posted 36MPG, then 40 MPG, and last tank got 44MPG. Speed was all interstate, at 78 MPG, cruise on. The bike is equipped with stock air cleaner and true (fulsac) duals with Carriage works Slips on it. Since I don't know the cams, and Don't know if there has ever been any kind of download, would the TFI still do any good on this bike? And if so, is it reliable, as in When I take a trip from Central Arkansastan to Washington state, will I have to worry it will fry out and leave me in the middle of Nowhereland, WY? Any suggestions?
