Bytetronik FA53 "Package B" self-tuning kit with Custom Remote Mapping (CRM) for the MINI Cooper S R53. Includes the FullAccess (FA53) self-tuning hardware/software for one vehicle (lets the owner flash stages and datalog themselves), a set of four Bosch 550cc fuel injectors with pigtails, an OBD-II extension cable for easier datalogging, and a one-time Custom Remote Mapping session where a Bytetronik tuner builds a bespoke map for that specific car. Requires a compatible Innovate wideband AFR kit already installed for the CRM session (sold separately, see the matching Innovate MTX AFR line).

Fitment: MINI Cooper S, R52/R53 chassis, W11 1.6L supercharged engine.
