Ok I.ve spent an hour examining the differences between the Leadshine Hybrid motors and the jss-motors (Changzhou Jinsanshi Mechatronics) copies... the pinouts for the DB9 are quite different... this is not a good sign for me using the Leadshine motor tuning software... There is an outside chance that the eeproms of both are the same and I can use the software to Rx and Tx if I just get the pin connections right, but it's unlikely. I will see what jss-motors recommend for tuning... I think JMC offer a hand held tuning device for their hybrid motors, maybe jss-motors do the same...
