Quote: whats out there besides the factory, and what MP offers?
can any of them actually retain mds? or perhaps link or control the auto?
what about the dual spark plugs, do they fire at the same time? or are they timed different?
FAST provides a complete EFI kit that plugs into your factory sensors. This includes the XFI ECU as well as the XIM module which is required for the ignition. The kit also includes a replacement 90 mm throttle body that is cable driven since "fly by wire" is not supported. MDS is also not supported.
The 5.7 kit controls the coils same as the factory (waste spark for the extra plug). The 6.1 kit removes the 16 plug requirement.
