All OBD and Bench protocols for ECUs are rounded up in this module. This module can use FLX2.10 or FLX2.11 cables (general purpose OBD and ENET cable). An increased programming speed compared to X17. Stability of protocol is even higher, which allows for safer writings even in less expensive working environments. In case of Master & Slave ECUs, Flex will automatically recognize the Slave ECU and write the same file loaded to the Master ECU to both – now there will be no reason to worry about remembering to write both ECUs manually!
