In case anyone is interested.....the above mentioned numbers are software downloads provided by Harley Davidson. They pertain to Harley components only i.e. Screamin' Eagle parts and are loaded via the old cartridge method......you cannot read or alter the settings. Tourbox, I purchased a Vance Hines Fuelpak for $150......brand new in the box. Should have it installed and programmed shortly. Thanks again for your input.
