Q: can somebody help me with my question… when built in a second hand ecu… from another came, same HW and SW… example edc16 or ME9.7…. can i adapt it through obd..?
A: Mate this tool is not made for this job. It is a good tool ( i think, i dont have it ) but for MB key making-repairing, read-write eis-ezs and jobs like this. I dont think it is good tool for reading-replacing ecus even if it has this function in SW.
