Hi,
As MalcolmG said, which package are you referring to? The Feb 2016 onward versions of the GP Packages have Flex Fuel in them already, as well as most of the targeted Packages.
M1 Flex Fuel User GuideCruise control is currently only available in targeted packages for vehicles that have OEM Cruise Control, and that retain the factory fail safes. We are not planning on implementing a generic cruise control system into the GP packages.
