after 25 yrs wife finnally ok'd harley,never give up! ran in and bought 08 ultra before she changed her mood. somewhere before closing i went thru the gauntlet of the dealers sales and service people. I know I heard the service manager say "we set ours at 13.something" but I didnt know what he was talking about. Since hooking up with this site iv learned. Is it possible they map ecm richer than 14.7 on a new 08 due to all the issues? He was discussing AC,slip-ons and warranty issues but his 13.? comment was at the beginning of intro to service dept. I dont have any issues with overheating and the bike runs great but plan on AC,slip-ons and TFI for standard reasons. wouldnt any thing in the 13's be out of range for o2 sensors? this is dealer whose service and parts depts told me not to use synthetic oil in crank so im already concerned who can service my bike.
