I think you need the Can bus cable for the M620 on the Z1. They sell them on aliexpess in China, but I wouldn't know which specific one to buy,
has anyone tried to use this cable to program their CAN Bus M620 ? any tips would be helpful (if it works) Thanks https://www.amazon.com/dp/B0B2MVPYX1/?coliid=I2OG68DFL463P3&colid=2V7VDVL9TKBKK&psc=1&ref_=lv_ov_lig_dp_it
