While the information presented is similar from Convention-to-Convention, he always looks for ways to whet owners’ interest in “coming back for more”. As atprior Conventions, his remarks addressed such questions as Will EFI prevent vapor lock? Will I see an increase in mpg? Should I allow the computer to control spark advance?How hard is EFI to install? During his Elkhart presentation, owners expressed much interest in the vapor lock prevention aspects of electronic fuel injection.Owners also voiced much interest in the FiTech alternative to the Howell/EBL system.
