MOTOROLA MPC5XX SLAVE SW PACKAGE FOR FLEX The FLS0.3S software package allows the SLAVE user to work on BDM protocols. This programming mode is used for communication with ECUs that mount the Motorola MPC5xx family of microprocessors. This type of microprocessor can generally be found on older generation vehicles fitted with EDC16 or MED9 ECUs. MAGICMOTORSPORT recommends that this SW package be used with FLEX and the complete FLEXible Bench kit (or FLEXible Bench upgrade kit for MAGK00030.V2) to obtain more efficient results and safer working conditions with no connection errors.
